An angle grinder is a hand-held power tool which can be used for a variety of different works including cutting, grinding, cleaning and polishing surfaces. This variety of works make it an essential tool that you must have in your arsenal. Although all the manufacturers make almost same angle grinders according to their main features, they have some differences in their motor and build quality.

You can get one at a very low price. But as you know the saying “You get what you paid for”, you have to increase your budget if you want to own a quality product. If you buy one with the lowest price, the quality and the motor would not be able to make you satisfied. The blade wouldn’t also be sharp enough. Overall it will be annoying. So, I recommend buying one with a little bit high price.

Different Types of Angle Grinder

There are different types of angle grinders available in the market. Different types of grinders are used for different types of works.


It is the most common model. They run through electricity. They need to be powered with 230 volts for general and domestic use or with 110 volts via a step-down transformer for professional and building site use. They can range from 500 – 2,000+ watts in power with the lower wattage items being at, the cheaper end of the scale.

They are also available in the wireless model which can be operated with a rechargeable battery. The most common battery used for a grinder is an 18 volts lithium ion battery. They are instrumental as you can take them wherever you want without thinking about the availability of the electricity. Just be sure that the battery is fully charged. And if you can take an extra battery with you then you can remain totally worry-free.


Another outstanding model is petrol angle grinder. They have a small petrol engine that contains petrol and powers the device. They are somehow very large scale angle grinder in size. They can be mostly used for cutting. You can cut steel, break or block, paving slabs etc easily with the petrol angle grinder.

One thing you have to take you into account that these type of angle grinders are not suitable for grinding at all. If you need an angle grinder for grinding then this model is not for you. If you just want to use it for cutting different materials, then you are welcome. It cuts really good.

Pneumatic or Compressed Air

These angle grinders are mostly found in a professional situation like a garage or workshop. The air to drive the tool is produced by a compressor and then channeled via pipes to the tool itself. Then the air drives the grinding or cutting disc. These tools often operate at slower speeds than the electric models.

These discs are tripped with a diamond at their edges so that they can easily cut off those hard materials mentioned above. Diamond cutting discs are of two types: wet and dry. Wet discs need to be wet while cutting but the dry disc doesn’t need any water.
