How to Choose the Best Angle Grinder

Choosing a grinder tool isn’t easy. The plethora of the options available makes it difficult to decide. As you list down some of the top picks, below are the most important considerations.


The type of the angle grinder largely impacts its functionality. Here is a quick rundown of some of the most common types that you will find in the market:

  • Corded Angle Grinder: You need a socket where you can plug this angle grinder for it to work. It is often the most powerful, but some people do not like its mobility limitation. The length of the wire can be restrictive, and you cannot use it anywhere.
  • Cordless Angle Grinder: If you are looking for a more portable angle grinder, go for a cordless model. It comes with a rechargeable battery, which means that you can use it even in places with no electricity as long as it is charged.
  • Pneumatic Angle Grinder: Working with metal is easier when you have this angle grinder. It connects to an air compressor unit. It uses pressure to function. This is also one of the cheapest options you will find in the market.


An angle grinder has different components, but one of the most important is the disc size. If you have a powerful motor that is designed for heavy-duty tasks, then you will need a bigger disc, which makes it more capable. The most common sizes are 115mm and 230mm. Take note of the work that you intend to accomplish, so you can choose the size of the disc that works best for your needs.


It is crucial to consider power as it is indicative of the overall performance. If you will use the angle grinder for light tasks and if you are a newbie, then go for one with lower power. The more powerful it is, the more expensive the unit can be. More so, as you evaluate power, the most important technical spec to look at is the wattage. A higher wattage is more suitable for difficult tasks.


To determine the speed of the best angle grinder, you should look at the rotations per minute or RPM. Some will have a single speed. Nonetheless, if you want the tool to be versatile, you should choose one with a variable speed. This way, its speed is customizable depending on what is more suitable for the job. Most will have a speed range of 6,000 to 8,000 RPM.


Consider the features that will be highly influential of your comfort. For instance, it must come with a lightweight body, which makes it easy to hold. This will minimize the strain on your wrist, especially for working at an extended time. It is also vital to have an ergonomic handle, so holding the unit will not be a burden


One of the most common safety features is slow start, which prevents the twisting of the motor by starting slowly instead of quickly going into a full blast. Anti-kickback is also a great feature, which automatically sops the wheel upon binding. Some will also have a paddle switch, which promotes safe operations by starting the motor only when the unit is held by two hands.
