Angle Grinder

Designed for cutting metal and stone, the blades or "cutting discs" vary according to the material. A thinner disc should be used on marble rather than on a paving slab. Angle grinders can be used for cutting and also for grinding (such as smoothing rough edges on a heavyweight surfaces like masonry). Protective clothing is necessary when working with an angle grinder. Remove all combustible materials from the area before cutting metal, because showers of sparks will be produced.
