Buying Guide & Points to Ponder

The angle grinders are an essential part of a fabricator’s shop. They are mainly used to clean the metal surface before welding or cut it after welding. Like if you are working with rusted or painted metals then they should be cleaned before welding.

Any good angle grinder can make the surface of any rusted metal shining in seconds. The second user can be to clear the slag after welding the metal or remove impurities from the weld to achieve stronger welds. The last use of an Angle grinder is to use it for cutting metals.

A plasma cutter is best for cutting metals, but angle grinders can also achieve this task for appropriate metals.

To accomplish all these tasks, the selection of an angle grinder is crucial. The choice of a kind machine can be based on several factors. I will try to cover all the elements that emphasize the purchase of an angle grinder.

Cordless or Corded

Cordless machines are handy to use and offer convenient operations. But they have a significant drawback of not giving high power outputs. The batteries die faster, but if you are working in a workshop or have an extra set of batteries, these machines can be magnificent.

You can take them anywhere with you without the trouble of finding a power source for the Machine. In this list, I have mentioned very efficient Cordless Angle Grinders like DeWalt DCG413B and Milwaukee 2780-20 M18 Fuel Angle Grinder.

On the other hand, Corded Angle ground can offer more power output and higher torques. These machines are relatively heavier than cordless machines, and you can’t use them outside your workshop. But these machines offer excellent features that are unavailable in cordless angle grinders. We have listed many right corded angle grinders like Makita 9557PBX1 Angle Grinder and PORTER-CABLE Angle Grinder.

RPM Ratings

RPM stands for rotation per minute. This feature tells us the number of times a disc will rotate in one minute. A machine with a higher RPM rating can deliver higher torque and is best for big jobs. Whereas, a device with a low RPM rating is suitable for garage jobs or amateur fabricators.

We have mentioned angle grinders for tough jobs and having high RPM ratings in our list like Makita 9557PBX1 Angle Grinder and PORTER-CABLE Angle Grinder.

For lighter jobs, we have mentioned some machines with low RPM ratings like DeWalt DCG413B. This Machine is excellent for lighter tasks and does not require any special skills to operate.

Power and Ampere Ratings

Angle Grinders with high Amperage ratings can do tough jobs and have higher RPM ratings. They are best for professionals or industrial uses. Beginners or amateur can rely on an output rating of 5-8 amps for delivering all kinds of jobs to them. These machines are cheaper and usually lighter in weight. We have SKIL 9295-01 6.0 Amp 4-1/2-Inch Angle in our list which is the first low-power device.

The machines with higher Amperage ratings are for professional works and require skills to operate on. In our list, Bosch GWS13-50VSP High-Performance Angle Grinder is one of those machines.

Disc Type & Disc Size

Angle grinders use different types of discs during their operation. There are usually four main types of drives that are used with an angle grinder.

Cutting Discs: Cutting discs are the thinnest discs and are used to cut metals. They have sharp edges and are available in different sizes. Most of the machines come with one or more cutting discs.

Grinding Discs: These discs are used for smoothening the metal surface or tasks like clearing slag. They are usually 5mm thick. An excellent grinding disc can clean the edge or the whole metal for further use.

Flap Discs: Flap discs are covered with sandpaper and are particularly good for giving finish to the workpiece. These discs have a grit number on them. The larger the grit number, the finer the grit is, and the shinier the finish.

Wire Brush Discs: These discs are like grinding or flap discs and are mainly used to clear the rusty surface of the metal.

The size of the disc is also an important factor in grinding jobs. The most popular size of the disc is 4-1/2″. These discs are versatile in operation and efficient in tasks. Apart from these other disc sizes are also available.

Angle grinders usually work with one disc size, but some individual machines can operate with more than one disc size. Milwaukee 2780-20 M18 Fuel Angle Grinder is one Machine with variable disc size options.

Changing the disc should be more comfortable and convenient for users. Different devices offer different techniques for improving the disc. The disc changing operation can be tool-less or with the help of a small tool like a wrench. The tool-less procedure of changing the disc is convenient and easier for users to do so.


An angle grinder is a handy device and is used frequently for different types of jobs. If your Machine is not durable, then you cannot use it for longer durations. Some machines have additional safety procedures like a metallic body or cooling mechanism for the motor.

Brushless motors also ensure longevity. In this list, we have Milwaukee 2780-20 M18 Fuel Angle Grinder that offers excellent safety features against mishaps.


As a large variety of machines are available, there is a wide range of prices. Most of the angle grinders are cheaper. But if you want a quality machine then you have to pay more price. In either way, you have to make sure that your hard-earned cash makes you happy as Larry.
