A spark suppressor and spark- suppressing rotary abrasive tool having at least one non- smooth spark energy dissipating surface or layer disposed adjacent a spark generating region where there is abrasive contact between a workpiece and rotating abrasive implement of the tool. A preferred spark suppressor is a spark suppressing protective guard for the tool having a spark energy dissipating surface or layer within disposed adjacent to and facing toward the spark generating region. A preferred spark-suppressing rotary abrasive tool is equipped with such a spark-suppressing guard. A preferred spark energy dissipating surface is of three-dimensionally contoured construction having at least a plurality of upraised portions against which sparks generated contact dissipating their momentum and velocity until stopped and retained within the spark suppressor. A preferred spark energy dissipating layer is formed of a plurality of wires or pins that can be entangled to form a porous non-woven spark catching layer.
