Best hole saw kit of 2018
The “Total” indicates the overall value of the product. I’ve based my selection methodology on customer feedback, the size, functionality, and budget to meet various demands. You can make a choice based on the my list as you shop. Not all hole saw kit are created equal though.
Test Results and Ratings
№1 – Meccion Hole Saw Drill Bit Kit Wood Sheet Metal Cutter Mandrels Saws 3/4 inch – 5 inch 16pcs Full Set
Why did this hole saw kit win the first place?
I am very happy with the purchase. It is definitely worth its money. The product is top-notch! I don’t know anything about other models from this brand, but I am fully satisfied with this product. The product is very strong. Its material is stable and doesn’t crack. The rear part fits perfectly! It is mounted really tight and reliable.
Why did this hole saw kit come in second place?
I recommend you to consider buying this model, it definitely worth its money. This is a pretty decent product that perfectly fitted the interior of our office. Seems that the material is good. It has a very beautiful color but I don’t really like the texture. I really liked it. It is amazing in every aspect. It did even exceed my expectations for a bit, considering the affordable price.
Why did this hole saw kit take third place?
The material is incredibly nice to the touch. It has a great color, which will suit any wallpapers. I liked the design. We’ve been using it for 2 months and it still looks like brand new. It is inconvenient to use due to the size. I am going to get something different next time. This price is appropriate since the product is very well built.
hole saw kit Buyer’s Guide
The body of a hole saw is a wide diameter metal cylinder. Regardless of your cutting edge, steel is standard across the lion’s share of industries. The cylinder is mounted on an arbour, and you’ll notice slots cut into its walls to facilitate the ejection of chips and dust for smooth performance and to prevent stuck blades. Slot number varies between makes and models – is generally the upper limit since more would compromise the hole saw’s strength, and we wouldn’t want that.
Here’s where things get interesting. The metal cylinder of each hole saw culminates with an edge that uses either serrated saw teeth, gulleted/square teeth, or ultra-hard embedded materials to cut through your workpiece.
Serrated Saw Teeth: Typically set at a 60° angle to allow a penetrating bite into the material being cut, saw teeth are far and away the most common cutting edge. Use saw tooth hole saws for wood, plaster, softer metals, and plastic.
Gulleted/Square Teeth: Teeth are wider set since raw power is preferred over fine cuts. You’ll use gulleted or square tooth hole saws with more abrasive surfaces, including concrete, brickwork, ceramic tiles, glass, and stone.
Coated: No teeth are used at all. Instead an ultra-hard material, usually tungsten carbide or diamond, coats the cutting edge. More of a niche tool, you’ll use coated hole saws to cut through heavy-duty metals, ceramics, and concrete. Unless you’re a professional, you’re unlikely to encounter the need.
You’ll also want to pay attention to the pitch of teeth and their TPI (Teeth Per Inch) rating, so let’s break down the impact of each factor.
Pitch refers to the distance between the point of two teeth (serrated) or the middle of two teeth’s gullets (gulleted/square). A variable pitch hole saw varies that distance, while a constant pitch hole saw maintains the same distance.
Understand TPI as a measure of tooth frequency along the blade. For example, 1TPI means 1teeth per inch, so that tooth frequency is higher than that of a 1TPI hole saw. TPI numbers vary, but they stay within the general ballpark of 20 to 2.
The arbor isn’t specific to the hole saw, but it’s a vital part nonetheless. It’s the type of tool bit used to grip other moving tool components, essentially the connecting part between your hole saw and your power drill. Most, but not all, hole saws are supplied with an arbor – you’ll occasionally need to purchase your own, so pay attention when you buy.
As you’re browsing, you might consider seeking an arbor with a spring placed over the drill bit. These are known as ejector springs – they contract as you drill and then eject the slug (the cut segment) after the hole has been made.
Arbors can be broken down into fixed or detachable and small or large.
Fixed Arbors: Said to have an ‘integral shank’, fixed arbors come attached to the hole saw blade. Using one means skipping any dismantling when you need to change saw size.
Detachable Arbors: Unfixed to the hole saw, detachable arbors can be used with a variety of blades. Using one means skipping the need to purchase again for every hole.
Size comes down to the diameter across the flats of an arbor’s hexagonal shank – so, the distance between one flat face to the opposite flat face.
How to Use a Hole Saw Perfectly
Hole saws seem misleadingly easy to use. It’s no mere matter of choosing a spot before pressing down with your drill, and practice must make perfect until you’re confident. During your first few attempts, try using a practice workpiece.
If your hole saw should become dulled, the relatively low cost of replacing the blade should be enough to dissuade you from sharpening. If you’re set on sharpening, you can use a hand file on each individual tooth, though a hand-held electric grinder will slightly cut down on elbow grease. A bench grinder also does the job, but extensive time and concentration is required – honestly, it’s largely advantageous to replace instead of re-sharpen.
Outfit yourself with
Eye Protection and Mouth Guard: To prevent dust or splinters getting in your eyes or being inhaled.
Safety Gloves: To maintain proper purchase through cutting.
Ear Protection: To safeguard your hearing while drilling for extended periods.
If working with any material save wood or cast iron, cutting oil or lubricant must be used to reduce resistance and extend the saw’s life. When using a more powerful drill to cut through a tougher material, the machine may experience ‘kick back’; under such conditions, you’re well advised to use a drill with a side-handle to afford additional stability and control.
Setting up the Job
Obviously, the material base to be used must be ferrous metal for the electromagnet to work properly. The material type dictates the type and grade of the cutting tool to be used.
The first step is to make sure you have a clean, flat, and smooth work surface that is free of chips. Make sure the bottom of the magnet is also clean. Any foreign matter such as chips under the magnet could rock it and decrease its holding power, resulting in the drill rotating or shutting down because the safety mechanism was activated. If the surface is not perfectly flat, such as an I-beam that has a crown, you need to make sure the magnet is not affected. Placing the magnet to one side and not over the crown will give better results. The use of a swivel-base magnetic drill might help in this situation.
If the surface is heavily rusted or covered with paint, especially epoxy, the magnet may not obtain good holding power. Special care must be taken to ensure proper magnet adhesion. The proper, well-sharpened cutting tool may help in this situation because it may put less stress on the magnet while making the hole. Or this may be a good time to step up to cobalt or carbide cutting tools.
Using a safety chain or strap is critical in the event of a loss of power (see Figure 4) or if the drill safety circuitry shuts itself down because it will ensure the drill does not fall on or injure you.
Coolant Extends Cutter Life
Proper use of coolant is essential to good cutting tool life and drill performance. Many magnetic drills come equipped with gravity-feed coolant systems, while others have arbors with internal coolant reservoirs. Coolant for annular cutters should be high lubricity-low viscosity.
If a drill is not equipped with a through-the-tool coolant system, you should never just squirt coolant on the cutter because it will just spin off during drilling instead of getting to the cutting teeth where it is needed. In this instance, a good stick lube placed on the cutting teeth will do the job. Stick lube is a waxy substance that will adhere to the teeth of the cutting tool and will last for one hole. It should always be used when drilling in the horizontal and overhead positions.
For deep-hole drilling, a pressurized coolant system will perform the best and help to extend tool life. Running cutters dry builds up excessive heat, shortens tool life, and possibly results in an inferior hole.
Once you have selected the right tool for the job, set up properly, and figured out your coolant needs, you are ready to commence hole-making with the magnetic drill. These tips can help you avoid excessive downtime.
Use the right cutter for the application. Annular cutters are material-specific, and using the right cutter will result in optimal tool life. Although many tool manufacturers supply data on what types to use with specific material, consult with the cutting tool manufacturer when in doubt. In some cases, the manufacturer may suggest a custom tool, such as an extended-reach cutter for deep-hole drilling.
A major cause of broken or prematurely dull annular cutters is a slow feed rate. A firm, aggressive, and steady feed pressure throughout the cut, where you can hear the motor work but not overly labored, results in a good hole and long tool life provided coolant and the proper cutter are also employed. A good feed rate also will result in a healthy chip coming up out of the flute, keeping the cutting teeth free to do their job.
When the hole is finished, you should see a good birdnest on the cutter. A slow feed rate results in a thin chip that can start to break up and pack up in the flutes. This either slows down or stops the cutting action and possibly could destroy a cutter.
A dull cutter also has a tendency to lift the magnet, which can lead to a broken cutter. If the cutting action is diminished, sharpen or replace the cutter. Pecking the cutter also breaks up the chips instead of working them up the flutes, causing the same problems.
Figure 4: A safety chain ensures the magnetic drill is not damaged or the operator injured should the electricity cut off. Such precautions can prevent expensive losses. One contractor rehabbing a bridge in New York lost a majority of the 40 drills being used when a power failure occurred and the drills ended up in the East River.
Make sure the slug ejects at the end of the cut. Drills with a positive slug ejection feature accomplish this automatically. Spring ejection systems do work, but are not as reliable. For example, the cutting action generates heat, resulting in a slight expansion of the slug that could cause it to get caught in the tool. Removal of a slug can be time-consuming, and you run the risk of breaking the cutter while trying to remove the slug. Remember, the edge of the slug is very sharp, so handle with care.
After completing a hole, clear away chips and excessive coolant from the work surface, particularly when making additional holes. Also check the coolant level and cutter condition and make sure the slug is ejected.
Good Maintenance Can Extend Drill and Tool Life
When all else fails, read the instructions. They will provide good maintenance procedures for you to follow.
Additionally, some good, commonsense advice should be followed continuously.
Obviously, power cord and electrical switch conditions need to be checked as well.
Hard Woods vs Soft Woods
Typical hard woods include ash, beech, cherry, ebony, maple, mahogany, oak, rosewood, and teak.
Cutting porcelain tiles
Advancements in production techniques have made porcelain tiles more popular than ever. Although ceramic tiles are made from a soft mineral clay substrate topped with a glaze, porcelain tiles are fired at higher temperatures and pressures. This liquefies the mineral into solid glass, so the tile itself is much harder and denser, making it ideal for a wide variety of applications. However, this makes it very difficult to cut using a simple tile cutter, and porcelain tiles are also more prone to chipping during the cutting process.
Consider replacing the pilot drill with a hole enlargement arbor. The arbor can be fitted with a hole saw with the same diameter as the existing hole — this acts as the pilot — as well as a larger diameter hole saw, allowing the larger diameter to be cut in one single motion.
Cutting thick steel
There’s nothing more frustrating than when a tool breaks unexpectedly. Cutting steel is a perfect example of something that can cause this. Although regular hole saws will do the job, cutting thicker steel can cause the tool to become hot, quickly increasing wear on the cutting surface and significantly reducing product life.
When cutting thicker steel, consider using a carbide tipped hole saw designed specifically for deep cutting of steel up to 25mm thick. This operates at a higher speed for a faster cut, preventing the saw from getting hot and wearing down. By taking such precautionscontractors can increase the lifespan of their power tool accessories and deliver a higher return on investment.
Dust and debris
Although maintaining a clean working environment is a habit of all good tradespeople, it is inevitable that most jobs will produce excess dust and debris.
Get the job done
There is no reason for advances in materials to get in the way of tradespeople achieving perfection. With a little ingenuity and the help of a few specialised tools, people of all trades can stay ahead of the curve and get the job done without hassle.
For around-the-house drilling and driving needs, there is no better option to turn to than the Ryobi 90-Piece Drill and Drive Kit. This set replaces our previous pick, the Ryobi 90-Piece Drilling and Driving Accessory Kit, which has been discontinued. The only functional difference is that the general purpose bits in the new kit are coated with black oxide and not titanium like they were in the older kit. After testing, we’re more than satisfied with their durability.
Ryobi has discontinued our previous pick and runner-up and replaced them with nearly identical drill bit sets. After spending three months testing the new versions, we’re satisfied with their performance. Our new pick is the Ryobi 90-Piece Drill and Drive Kit, which offers the widest variety of useful accessories for drilling holes and driving screws. If the Ryobi 90-piece set isn’t available, our new runner-up, the Ryobi 60-Piece Drill and Drive Kit, is also very nice. It has all the same essentials, just in smaller quantities.
The Ryobi kit contains two 1/8-inch and two 1/16-inch black oxide bits. In my experience, these are the most commonly used and most often broken sizes. Having a spare of each is a nice touch.
The main selling point of the Ryobi is that it comes with a full set of 2general-purpose black oxide coated bits and a smaller five-piece set of brad point wood bits. The brad points have a centering tip that makes for high-precision work. Because there are two bit sets, I’ve been using the black oxide ones for the aggressive and dulling work, like drywall anchors and pre-drilling for basement shelving, while saving the brad points for the delicate work, such as furniture repairs and kitchen shelving. It’s also important to note that the Ryobi kit contains two 1/8-inch and two 1/16-inch black oxide bits. In my experience, these are the most commonly used and most often broken sizes. Having a spare of each is a nice touch.
The black oxide bits max out in size at ⅜ inch. For larger holes, the Ryobi has a four-piece paddle bit set that goes up to inch. Beyond that is a four-piece hole saw set that goes up to 2⅛ inches, which is unique to the Ryobi kit. In addition, there is a five-piece masonry bit set.
The Ryobi kit also includes four depth stops, which are collars that can be locked on to a drill bit to set them to a specific drilling depth. When I installed a keyboard tray on the underside of a desk, these prevented me from drilling through the top of the desk. Most carpenters I know will simply wrap a piece of blue tape around the drill bit at the right depth and stop drilling when it makes contact with the wood, but using the depth stops is easier and much more accurate.
The screw on the left was driven into the plywood without any prep. For the middle screw, I used the countersink first. Notice how much cleaner it is. The countersink is one of the high points of the Ryobi kit.
A Ryobi masonry bit still going strong after making 21-inch-deep holes through a cinder block.
And as for durability, I’m more than satisfied with the Ryobi kit. Using the ⅜-inch masonry bit (the largest supplied), I drilled more than two dozen 1-inch-deep holes in a cinder block without the bit really slowing down.
The general purpose bits in the Ryobi are coated with black oxide. While titanium is technically preferable, the reality is that either one will deliver good performance. As mentioned earlier, the tester in the Family Handyman used a black oxide bit to bore 160 holes in a combination of pine, oak, aluminum, fiberboard, and steel. It was only after he drilled another 2holes in steel that the bit started to wear out. To satisfy our own curiosity, we took the largest bit from the black oxide Ryobi kit (⅜-inch) and drilled 100 holes into a two-by-four, 2holes into a 1/16-inch-thick aluminum, then another 50 holes in the two-by-four. After all this, the bit was still drilling with no problems. It should be fine for around the house work.
Flaws but not dealbreakers
Another potential flaw of the Ryobi kit is that the case doesn’t exactly scream durability. The lid is held on with three plastic hinges. The sliding latch is also plastic and sometimes needs to be wiggled to get it lined up properly. Overall, our test unit is still in fine shape, but a serious drop on a concrete floor would do some damage. The flip side of this is that a real construction-ready case would add significant bulk, as well as cost, to the Ryobi kit. As long as you’re careful with it, this case should be fine.
If the Ryobi 90-piece set isn’t available, the 60-piece set is also very nice. It has all the same essentials, but in smaller quantities.
If Ryobi’s 90-piece kit isn’t available, our second choice is Ryobi’s 60-Piece Drill and Drive Kit. Even though it’s smaller than our main pick, it still has far more useful pieces than any other kit out there. The 60-piece kit has the same basic selection of items as the larger kit, but just in smaller amounts. There is only one hole saw size (instead of four) and only one paddle bit (instead of four). It’s missing the depth stops and the selection of 2-inch driver bits, both of which are nice to have, but not essential. Spending a little more for the larger 90-piece kit is definitely worth it, but this one could work just fine instead.
The Basics Of Circular Saws
The cordless design should be your choice if you like portability and versatility when working. Moreover, they are essential if you are working on areas where extension cords or power outlets are not available.
A cordless circular saw is smaller compared to a corded design. Therefore, they are perfect if you have a small or confined workshop.
There are various sizes available for a corded design. However, the most common are the 1/model. If you are required to work on large areas, you may need an extension cord. Typically, the default wire of the corded circular saws is long already. However, having an extension cord will improve your versatility.
If you are usually dealing with heavy duty tasks, you may need a circular saw that has a high motor rating. Specifically, motors that can perform no-load speed of up to 4,000 RPM are more will suit you best.

The hole saw today plays a major role in almost every plumber’s toolkit. In order to bore precise holes for fitting wires and/or pipes, a hole saw is definitely a must-have. The hole saw is a round saw whose purpose is to bore circular holes in workpieces, provided that they are not too thick. In general, the hole saw blade may be attached to a drill in order to do the cutting.
Hole saws generally have a round metal blade made of a reinforced alloy such as steel, and they have saw ‘teeth’ in order to ‘bite’ through the material they intend to bore. These hole saws are commonly referred to as the metal hole saw. A drill bit can go forward in order to bore a hole through the very center of the circle. The teeth of the hole saw can bore holes in many types of materials such as wood, plastic, plaster or even the hardest metals such as cast iron. Hole saws may also be used in cordless drills with sizes ranging from half a centimeter to over twelve centimeters.
Hole saws are available in three levels of magnitude: for the smaller holes, the three-inch blade might suffice, for medium-sized holes, there is a 3.5″ available, and for larger holes, you can get a four-inch sized blade. For anything larger, you might want to consider a specially sized blade of up to six-inches, though this is always an exception. The best hole saw blades are made of a metal alloy such as steel since such metals are reinforced and will last many, many years. However, you can also get a diamond hole saw or a carbide hole saw if extra strength is needed.
The main selling point of a hole saw as opposed to other types of drills is its large width cutting capacity, as well as its efficiency, a very small portion of the area being removed is really being sheared, thus reducing the total power requirement.
A power saw can be a considerable purchase. That’s why the few minutes that you spend on reading power saw reviews is time well spent. Not only can you save money but you can also avoid headaches by purchasing only the right tool for your need. Here, I share my personal experiences and honest reviews about power saws to help you sense what it is like to work before you actually purchase one. My experiences and opinions act as a litmus test for first time users and for those who want to upgrade their power saws. Wish to help you identify the most significant factors that should influence your decision when buying the best power saws.
First off, I thought this was going to be bigger, secondly I thought this was actually going to CUT SOMETHING! Not only did this not stay in place while I was trying to cut a circle, but it also decided to not even cut the freakin bass drum head, much less a piece of paper. I honestly dont know how these other people got it to work but it would not cooperate for me. This is a good tool if you want to cut uneven and jagged edges. Lastly it leaves a cm distance from the edge (for me a Drum O) so as if putting on the rings wasnt hard enough, they had to leave a distance between the edge and the hole so its basically impossible to put on. If anything I would say go to Home Depot and buy a box cutter, because that is exactly what I used to finish the job it hadnt even started.
A hole saw is a type of accessory for drills capable of making very large holes in a variety of materials.
Most hole saws operate via a central pilot drill that bites into the material first. Then, a cylindrical saw blade of a specified diameter follows it and makes a perfect circular hole.
The central hole saw drill bit is part of a detachable accessory known as an arbor. This arbor is simply screwed to the blade before cutting commences. Some larger diameter saw blades feature arbors with two pins that lock into the blade. These pins prevent the arbor locking onto the saw blade if it jams in the work, and allow for tool-free removal. Replacement pilot drills are also available and have a flat section on their shanks for them to be securely fixed in place by a small grub screw.
Before you make any purchase, it’s important to make sure that the hole saw’s length (which varies between manufacturers and types) is ample to go completely penetrate the surface you are drilling.
Each type of hole saw is capable of cutting a select range of materials, some being far more durable and efficient than others.
Bi-Metal Hole Saws
Bi-metal hole saws have high carbon steel bodies and high speed steel teeth, providing both flexibility and durability. This heavy duty shatter proof construction allows them to be used on a very wide variety of materials including steel, cast iron, aluminium, copper, plastics, and wood. They usually have a maximum depth of cut of about 30mm.
For a comprehensive guide to the drilling speeds required for bi-metal hole saws, see ‘Operating Tips’ at the bottom of this page.
Single Tooth Hole Cutters
Though bearing only one tungsten carbide tipped (TCT) tooth, these hole cutters are extremely effective in timber and cement sheeting. They can cut up to five times faster than a carbon steel hole saw through wood, but need to be withdrawn frequently to clear any material from the blade and the work. They usually have a maximum depth of cut of about 50mm.
HSS Hole Saws
High speed steel hole saws leave very clean, round and accurate holes in steel and alloy sheets up to 2mm in thickness (depth of cut does depend on the manufacturer). They are much harder and durable than high carbon steel hole saws, but are’t anywhere near as flexible. They are most commonly used for specialised professional use such as electrical installation work.
TCT Hole Saws
These tungsten carbide tipped hole saw drill bits are designed for specialised cutting in very dense materials. They have the ability to cut up to 2mm thick stainless steel (depth of cut does depend on the manufacturer), and can also perform cuts in steel, fibreglass, glass-reinforced plastics, and other abrasive materials up to 4mm in depth. Again, these hole saws are most suited to professional use.
TCT Hole Cutters
Operating on a similar premise to single tooth hole cutters and TCT hole saws, these hole cutters feature multiple tungsten carbide tipped (TCT) teeth and can be used on a variety of materials, ranging from ceramic tiles to timber and fibreglass. They include both a high speed steel (for wood and fibreglass) and masonry hole saw (for ceramic tiles and cement sheeting) drill bit for use on multiple materials, and can usually cut about about 20mm deep.
Although these hole cutters are provided with a masonry drill bit, they should never be used on a drill’s ‘hammer action’ setting.
Diamond Grit Hole Saws
These hole saw drill bits are tipped with diamond grit and are capable of drilling holes through ceramic tiles, hard plastics, fibro cement, and fibreglass. Very similar to diamond drill bits, they are designed to be dipped in water after every 20 seconds of use. There is usually an optional guide that can supply a steady of stream of water and also centre the bits, as they don’t have a centring drill bit. If this guide isn’t purchased, the hole saw must be started on a 45° degree angle to the surface, and once it bites must be moved to 90°. They usually have a maximum depth of cut of about 30mm. Some will also have an arbor attachment available.
To ensure efficient cutting, it’s advisable after every cut to remove any material that may be still in the drill bit with a thin piece of metal.
Core cutters are tungsten carbide tipped (TCT) hole saws that are used for boring large holes in masonry. They take a masonry hole saw drill bit and the arbor has SDS (either SDS-Plus or SDS-Max) fitment slots, as core cutters can only be used on a rotary hammer drill. This is because they require the brute force of a rotary hammer drill’s pneumatic hammer mechanism to effectively operate and crumble the core. Maximum drilling depths vary greatly across manufacturers but start from about 30mm.
RPM = (320 x Cutting Speed) ÷ Bit Diameter ‘Bit Diameter’ is measured in millimetres (mm) and refers to the size of hole saw you are using. ‘Cutting Speed’ is measured in metres per minute (m/min) and can be sourced from the below table for the specific material you are drilling. Simply input both the correct bit diameter and cutting speed into the formula and calculate the required RPM for your application.
Please note that the calculated speeds should only be used as a guide, and that depending on the various factors at work, including the specific grade of the material and cutting fluid availability, changes may need to be made to the calculated RPM. It is best to start with a slower speed, observe the cutting action, and increase it if needed.
No doubt the most commonly referred variant of drill bit, twist drills are a mainstay in almost any machine shop and also a modder’s toolbox. We need them for drilling new mounting points, removing rivets from cases, making fill ports, etc. So it comes as no surprise that the field has some depth to it. I’m sure anybody who’s set out to purchase a set before has been graced with a frankly overwhelming set of options, with sizes, materials, brands, finishes, and prices all important considerations.
As the name implies, hybrid saws have features of both the cabinet saw and the contractor saw. They generally have the same power motor as contractor saws. They have a partial cabinet with the motor contained, which helps with dust collection and noise dampening. They can be tuned to be very accurate, yet they are lightweight and small enough to be moved around the shop.
Needs vs. wants
The next task is determining what you need to do with the saw. Be honest with yourself about how you plan to use it. Do you need to break down large sheets of plywood to build cabinets? Do you build furniture with relatively thin boards? Think about what you plan to do with the saw 80 percent of the time. If that consists of ripping hardwood less than 1” thick and occasionally cutting joinery, then a 1.7horsepower motor in a contractor or hybrid saw is plenty adequate. However, if you regularly need to rip thick maple, then you need an industrial strength saw of horsepower or more. Don’t make a purchase decision based on exceptions.
A table saw is definitely an investment. Because of the expense involved and the importance to the quality and enjoyment of your woodworking, it is worth your time to shop around. Search for reviews from reliable publications, talk with fellow woodworkers and read discussions on forums.
This innovative circle cutter and straight-edge guide attachment makes it easy to do more with your go-to rotary tool. Not only does it attach easily to the Dremel High-Speed Rotary Tool and cuts perfect circles from ¾-inch to 12-inches in diameter, but its straight-edge guide attachment allows for straighter cuts. Measurement guides in both inches and centimeters.
First of all thanks for reading my article to the end! I hope you find my reviews listed here useful and that it allows you to make a proper comparison of what is best to fit your needs and budget. Don’t be afraid to try more than one product if your first pick doesn’t do the trick.
Most important, have fun and choose your hole saw kit wisely! Good luck!
