Bench and Pedestal Grinding Wheels with Nylon Mesh for Deburring Metals

The abrasive-embedded mesh construction provides a cushioned grind. Also known as convolute wheels.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Medium—Medium-hardness wheels conform to surfaces better than hard-density wheels. Use for blending tool marks, light deburring, and creating a bright surface finish.

Hard and Extra Hard—Hard and extra-hard wheels are more durable for aggressive material removal and heavy deburring.
