An abrasive saw, also known as a cut-off saw or chop saw, is a power tool which is typically used to cut hard materials, such as metals, tile, and concrete. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel. Technically speaking this is not a saw, as it does not use regularly shaped edges (teeth) for cutting.

With these saws, lightweight steel fabrication previously performed in workshops using stationary power bandsaws or cold saws can be done on-site. Abrasive saws have replaced more expensive and hazardous acetylene torches in many applications, such as cutting rebar. In addition,
