Angle Grinder

Overview

An angle grinder spins an abrasive disc at high speed, and which disc is fitted determines the job: a cutting disc parts material, a grinding disc removes weld reinforcement or scale, and a flap or wire disc prepares a surface before coating. It is the single most-used hand tool in fabrication and repair work precisely because of that versatility, weld preparation, deburring a cut edge, and blending a repair into surrounding plate are three different jobs done with the same tool and a disc change between them. A guard fitted over the exposed portion of the disc is standard rather than optional equipment, since a disc running at full speed that shatters or binds is one of the more common causes of serious injury in fabrication work.
