What is an Angle Grinder

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 varity 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.
