What is a Grinder?

A grinder is a tool or machine used to grind or polish a variety of materials, including metal, wood, and stone. It typically consists of a motor that rotates a grinding wheel or disc, which can be used to remove material or shape the surface of the material being worked on.

Grinders can come in different forms, such as hand-held angle grinders, bench grinders, or larger industrial grinders used for heavy-duty work. They may also have different types of grinding discs or wheels, such as abrasive cutting discs, sanding discs, or polishing discs.

In addition to metalworking, woodworking, and stoneworking, grinders are also used in other applications such as sharpening tools, cutting tiles, or removing rust or paint from surfaces. They are commonly used in construction, manufacturing, and automotive industries, as well as in home workshops and DIY projects.
