What Is an Angle Grinder Used For?

An angle grinder is a multi-purpose tool which can be used for much more than grinding. Inexpensive and functional, this tool is a must have for the serious do-it-yourself homeowner.


An angle grinder is a hand held power-tool originally intended to grind metal. The most common use is to grind welds and smooth cut metal surfaces. Fitted with a variety of implements, the angle grinder can be used to cut tile, pavers and can remove paint and rust.


Angle grinders have an electric motor that powers a rotating spindle. A wheel is attached to the spindle and secured in place with a spindle nut.

Wheel Sizes

The most popular wheel sizes are 4 inch as well as 4 1/2 inch. Other wheel (disc) sizes can range up to 12 inches.
