An angle grinder is a powered tool that is used for both cutting and grinding operation basically, it uses a cutting disc or a grinding disc depending on the type of operation to be performed.
The tool rotates on a very high speed some as high as 2500 rpm and others 11000 rpm so that when the disc fails and pulls out or break loose the danger can be very high, although the tool has a metal guard to protect the user should a disc breaks loose
