 · Evan Doran. Associate Editor. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

For example, when grinding stainless steel, it's important to find an abrasive designed for heat-sensitive metals. Select a disc with a grinding aid for cooler running temperatures, like the 3M™ Cubitron™ II Fibre Disc …
