Product Description

Aluminum oxide bench and pedestal wheels for steel applications. Better performance level. Bushed to 1", 7/8", 3/4". All bench and pedestal wheels must be dressed to prevent loading. Loading can cause excessive heat, damage to the workpiece and wheel breakage. Dressing exposes new cutting edges and provides chip clearance. Do not grind wood, plastic or any other non-metallic material on a bench or pedestal grinder. Unsecured machines can move, causing grinding breakage and injury. Fixed-base bench and pedestal grinders must be secured.
