Weight & Dimensions
Angle grinders come in different shapes and sizes. Some are huge and bulky which are suitable for large industrial applications while some are small and portable and suited for compact workspaces. A large number of options are available in the market in both categories which makes it easier for the consumer to choose according to his workspace size and need.
There are various uses of a grinder. As the name suggests, the most common use is, of course, grinding or sanding away bulging, uninvited stone, metal or mortar. Construction workers use an angle grinder to make notches or cuts when working with metal or tiles. Bars, rods, and bolts can be cut easily using an angle grinder.
An angular grinder can be used for metal cleaning. If you have a more than years old car, which passes season after season of snow, rain, and heat, then nothing can you do about the car unless you have an angular grinder at hand. A wide range of corroded metal can be stripped, cleaned, deburred using angle grinders.
Why bother to buy a new tool when you can make your used ones running like they were bought yesterday? Tools those need a sharp cutting edge to perform their task well requires frequent sharpening. An angular grinder can restore cutting edges of tools like shovels, hoes, ice scrapers, lawn mower blades, hatchets.
An angular grinder can be used for removing paints from the wall or any metal. Unlike hammer and chisel, an angular grind will not break the brick. The task is dusty so don’t forget to wear a mask and protective clothes.
The size of your disk depends on what type of work you’re going to do. Large disks make it easy to do large and heavy jobs. On the other hand, a small disk is suitable for precise and detailed work. Small disks allow you to explore tiny corners without damaging the machine. Small grinders are available in 4.inches and inches size, usually enough for home projects. Professionals and construction workers may need a bigger size of inches or more.
Each angle grinder comes in different wattage, voltage and amp ratings. Grinders with a stronger motor are capable of working with harder materials. While grinders with weaker and smaller motors are built for working with softer materials. Angle grinders come in different watt ratings, ranging from 500-2500 watts. The Voltage ratings are generally between 110-230 volts.
The rotating speed is measured by RPM, which means revolution per minute. Best angular grinders provide speed ranging from 5000 RPM to 10000 RPM. Obviously, the more speed a grinder provides, the quicker your job gets done. But keep in mind that quicker grinder is harder to control that the slower ones. And faster ones tend to heat quickly.
Your grinder should have an ergonomic design that provides you with comfort. The comfort generally depends upon two things, the size, and the weight. If you intend to use the grinder for a long time simultaneously, you might want a smaller unit. Also, the grip should be comfortable enough to hold it for a long time. The grip should be anti- vibrant so that the vibration doesn’t travel back to your hand.
More powerful motor means more weight. Although power is needed, a hefty weight will make it tough for the worker to hold it continuously. Make sure you make a balance between these two.
Some grinders come with side handles. Although that’s not a must have feature, side handle is really helpful for better control and precision. Some grinders have detachable side handles that can be attached to the right or left, depending upon whether it’s used by a right-handed or a left-handed person.
Safety is important while using tools like an angle grinder. An angular grinder requires a great speed to perform its job well and without safety precautions, that might be dangerous.
Some people like to use angle grinders without the adjustable guard, thinking this will help to work freely. Honestly, I prefer otherwise. The guard is there for a reason and that is to protect you from speedy byproducts. Also, the guard is called adjustable because it can be adjusted to facilitate you to work at different angles.
Make sure your grinder has a “dead man switch’, which prevents the grinder from starting by accidentally pressing the start switch. It will be needed to turn the dead man switch off before working again after an interval, which is a nice mechanism to ensure your safety.
Also, your grinder should contain an electric brake system. The mechanism will shut off the grinder automatically in seconds or less if the machine gets overheated.
Dust ejection, paddle switches, spindle locks are some of the other features that not only keep you safe but also your machine by making it last longer and operate smoothly.
Just like you wouldn’t need a sports car if you live in an area where traffic congestion are rampant, you do not need high power motor for every job. If you need an angular grinder for house use or light jobs, purchasing a grinder that has the highest power won’t make sense, because you’ll never use full power. If you are just looking for replacing your conventional sand paper to remove paint, go for a lower power grinder if you’re looking for some high-end grinding and cutting task, go for a higher motor.
Corded Angle Grinder
By far the most popular, and certainly the most used type is the corded version. That is where the grinder is plugged directly into a main’s electrical socket, or an extension lead.
With that type the distinct advantage is that you will always have a constant power source to drive the motor. The disadvantage is that you will always need an electricity supply, and you will always have a trailing lead.
Motor Sizes and RPM
In this section we will look at the sizes of the motors, and also why the RPM is an important consideration. The general rule of thumb, when it comes to motors is that the bigger the motor, the more powerful the tool.
The same applies to the motors found on angle grinders. These range from as low as 500 watt motors and go all the way up to just over 2,000 watts. Now for the smaller 4-5″ grinders anything between 500-1,000 watts is plenty of power to drive that.
When you move to the larger 9″ models, you are going to need around 2,000 watts to drive the wheel, without stressing the motor.
Angle Grinder Accessories
In this section, we will look at what accessories are available that you can attach to your angle grinder, to make it a highly versatile tool.
These include, Grinding Wheels, Cut-Off Wheels, Wire Cup Brushes, Sanding Discs and Polishing Discs. You can also buy guards that have a dust extraction built into them.
One of the most popular accessories is the mortar rake. A popular choice for that is the Silverline 8mm Tungsten Carbide mortar rake.
One very useful accessory to consider is a stand for your grinder.
These hold your portable angle grinder in place, and allow you to use it in a similar way to a chop saw. They are a bit fiddly to set up, but they do work well when you get that initial set up completed.
I enjoy writing about tools and gadgets of all kinds. As an electrician and with many years working in the building industry, I have used my fair share of all the leading tool brands. On this website I share my experiences of these along with my colleague Geoff.
If you are eager to do some heavy works with an angle grinder regularly, DeWALT DWE40is the best angle grinder for you. It is designed for them who want to perform some heavy work as well as not eager to cost much. This tool has 1AMP AC/DC motor which let the wheel spin at 11,000 RPM speed. As a result, you will get the best performance at this weight/size ratio. You can cut bricks with this tool.
Unlike the previous models, this model contains an oversized brush to ensure the brush life twice. To prevent tool damage, auto off brushes shut this tool down whenever the brushes need to be replaced. The hand grip is also designed for the comfort of the user so that the user doesn’t feel any problem working with the tool for a long time.
If you do versatile works randomly, you may find it to be disturbing replacing the wheel. But this tool has a quick change wheel release which will let you change the wheel quickly. The amazing dust ejaculation system pulls away the dust produced and you will feel comfortable to work with it.
Comes with a year limited warranty and a 90 days money back guarantee.The guard has a quick release lever that makes it much convenient to move around. Also the side handle can be adjusted to different positions which allows a user to adjust the tool as per the task & at the same time maintain control & precision.
I personally like the fact that the guard can be adjusted without using any additional tools. With the slide switch, you can easily switch between the wheels. This ensures that you save a lot of time between different guard change. Sometimes the switch may get jammed if you are doing woodwork as there is no proper insulation which protects the switch from dust & wood shavings.
Areas of Improvement
A small complaint noted by certain users was the lack of case or bag to house the grinder & its accessories. Now if you are carrying this grinder to a remote job then yes this could be an issue as a bag could come in handy for keeping all the different wheels, different guards, wrench & grinder together.
So better option, If you are looking for a grinder with cutting wheels then probably you can check out which also comes with cutoff guard and grinding guard along with multiple grinding and cutting wheels.
The paddle switch is one step ahead of the cheap ones available in the market. It has a locking/non-locking paddle switch with an ease of usage. The switch runs through the entire length of the grinder and there is no limitation as to how can you hold it but the moment you leave it or let it go, the tool will stop.
There is a small latch positioned in the middle that needs to be flipped before the paddle switch can start working. No many other grinders provide Thumb Switches which forces you to hold the tool in a particular fashion so that you can reach the switch when you want to turn the grinder off. But this may not always be ideal scenario as you want the switch to be available whichever way you hold the tool.
This grinder comes with a nice case, various grinding wheels and a diamond cutter.
In all, the Grinder’s extra-large paddle switch makes it pretty comfortable to work with and it cuts through U-bolt and iron plate readily enough.
If you want to use this machine it is advisable to use it with Safety Glasses. If you are ordering this machine or any other grinder please do as well.
I also purchased a so that I could use it to remove rust from furniture kept outside, lawn equipments etc.

In an effort to ensure it serves you in the long-term, the package comes complete with stainless steel grinding discs.
This is your ideal angle grinder if you are working on less demanding projects. It is strong and durable. It allows for versatility thanks to the extra included blades.
As another hobby car restorer, I agree with DAF 45, but would like to add on the safety front- in addition to decent goggles and gloves and ear protection, also wear a dust mask, steel toe boots and a decent fire retardent overall (such as Dickes etc). Oh, and some head covering too (could be cotton baseball cap).
While there are several sizes that angle grinders are made in, they basically fall into two categories, small and large. The small ones range from 4” to 5” and the large from 7” to 9”. Smaller grinding disks can always be attached to a grinder, but larger ones can’t. It’s also important to take into consideration the maximum speed of any particular attachment.
Grinders rotate at high speed and the attachment must be able to withstand the rotational force without coming apart. These attachments typically have the max RPM stated on them to provide the user the ability to properly selecting their attachments.
This increase in cutting size means that you should pick the largest grinder that you can reasonably fit within your tool budget. That will ultimately save you time and have the tool pay for itself.
What to Look For in an Angle Grinder
When selecting a grinder, power and size are the two major considerations. The higher power allows you to put more pressure on the grinder, making a bolder cut. While speed and wheel size are important factors in grinding capability, the amount of pressure placed on the point of contact with the workpiece is important as well.
When buying inexpensive angle grinders, one of the best things you can do is to open up the gearhead and fill it with grease. The gears themselves will probably be greased, but by adding more grease you will help to cool the gears and allow them to last longer.
Of all power tools, angle grinders go through motor brushes faster than any other. This probably has to do with the fact that when these tools are used, they’re typically on for extended periods of time. Ease of brush replacement and availability of replacement brushes are both important factors for cases where the grinder will be used a lot.
Besides the two different size ranges of angle grinders that are available on the market, there are also cordless grinders. These are only available in the smaller size range, as the larger grinding wheel requires more power to operate.
Cordless grinders are great if you are working on a remote site, but can be a bit of a hassle in a workshop. Generally speaking, when angle grinders are in use, they are on for an extended period of time. Even though cordless angle grinders use Lithium-Ion batteries, the batteries can only power the grinder for a certain amount of time. If you’re using the grinder continually, you will probably need a total of three batteries and two chargers to keep the unit operating constantly.
Disc Dimensions and Specs
To evaluate designs against each other, you should know their specifications. What do they carry to the table? Makita 9564CV has the most effective motor at 12-amps, followed by the 10-amp the best angle grinder, then the 7.5-amp Makita 9557PB, last but not least the 6-amp Hitachi G12SRHowever, that does not mean the Makita 9564CV is the best, and the Hitachi G12SRis the most severe angle-grinding machine. You are only looking at one specification and one part distributed by all four designs.
You need to look further, like the proven reality that the Makita promotions are all of the 4.5-inch wide range regarding disk dimension, and the rest are the more “traditional” grinder. Bigger disks might mean quicker RPM and greater amplifiers for motors might mean more rapid burnout from certain tools. The less rough the disk, the better it is for improving. The rougher it is, the better it is for cutting and grinding the roughest of components. Your option should become a case-by-case foundation, eventually.
Quick to Use
This detail is quite simple to use. It is light, and the wheel switching features like a gyroscope, steadying it. It cuts, grinds, beaches and anything else you could consider without bogging down. It was also very low-cost. It is significant high quality and hopefully it to past an extended time.
A die grinder is a must-have tool when you are working with older steel or iron machinery. Since rust forms when iron is exposed to moisture and oxygen, whenever your iron or steel tools are exposed, they may rust over time. a die grinder can effectively remove rust using an array of accessories.
When you’re repairing your vehicle for collision repairs, you probably have to strip off the pain to work on the bare metal. Die grinders can come in handy especially when you want to get rid of paint in the smaller areas that may be hard to reach using a sander. Alternatively, to remover the metal sheet that needs replacing, you can install a cutting wheel onto the grinder.
Die grinder vs. Cutoff tool
Many die grinders are usually sold as cutoff tools that come with extras such as the installation of a guard, and a fibrous cutoff wheel. The cutoff wheel enables the grinder to cut metal bars and tubing. This means that if you buy a die grinder instead of a cutoff tool, you can convert it for cutting metal, and tubing, with a shield that protects you from metal sparks. The only difference between a cutoff tool and a die grinder is the shield.
Right vs. Straight Angle
Conventional grinders are straight, where the tool rotates perpendicular to the length of the tool. In recent models, manufacturers introduced the right angle die grinders, with some coming built at 30 degrees. In some types of operations, the angled head is much easier to hold, but all angles to have their place. A right-angle grinder is best suited for grinding wheels that mount on to a shaft, and still has a variety of types of tips that can be mounted on it.
Cordless vs. Pneumatic Just like with other power tools, cordless die grinders are now entering the market, offering users great portability and ease of use. Although cordless die grinders are usually longer than the pneumatic ones, not having to drag the power cord or air hose around allows them to reach into more areas, some of which pneumatic die grinders simply can’t. Cordless grinders are often used on remote jobsites by contractors than by people working in a shop. Of course, the benefit of working off a battery isn’t apparent when working in a shop with power available throughout. Moreover, cordless die grinders require stopping to change the battery periodically.
DEWALT DW840K 7-Inch Angle Grinder
You will get a carrying bag contained with 2-Position Side Handle, Adjustable Guard, Grinding Wheels, Wrench, and Backing Flange along with DEWALT DW840K.
Besides packing a lot of power, the tool-less disc change and tool-less guard adjustments are really a nice addition to this grinder.

To cut through tough rebar in concrete, attach a metal cutoff wheel, and make sure your tool is secured tightly. Drop the cutoff wheel right through the metal allowing the weight of the tool to control the drop. Using angle grinders rather than hacksaws are much quicker and easier, making this versatile tool hard to beat. You can also use high quality Metal Cut Saw for cutting so, read our review and find out more.
For sharpening your other tools, an angle grinder can’t be beat for its ease of use and power. Secure the blade in a vise or with hand clamps, then position the tool and adjust the blade guard to avert the sparks from your face and body. Then, align the grinding wheel with the angle on the blade, start the grinder and move the wheel across the blade while applying light pressure.
When buying an angle grinder, it is crucial to choose one with a handle that is versatile and adjustable, which allows you to position yourself different while using it. A good angle grinder should have features that consider right-handed and left-handed persons. You should consider buying an angle grinder whose side handles do not cause you strain due to its length or positioning. Moreover, an angle grinder with anti-vibration handle will allow you to use for a longer period, as it is more comfortable than one without.
