Arc Abrasives 59361 Surface Conditioning Disc 3in Coarse Type R

Product Description

The ARC ABRASIVES 59361 is a 3-inch surface conditioning disc designed for edge grinding on cold rolled mild steel and stainless steel sheet. The disc features an extremely flexible backing paired with 100 percent cotton abrasive construction, giving it the conformability needed to follow contours and edge profiles without gouging or chatter. Rated coarse and built for Type R quick-change mounting, this disc is a practical choice for metal fabricators and welding shops that need consistent surface prep on sheet stock. Sold individually, with a minimum order quantity of 25 units.

This disc is intended for use on cold rolled mild steel and stainless steel sheet metal in edge grinding applications. The flexible backing makes it well suited for situations where a rigid disc would lose contact with the workpiece, such as deburring sheared edges, blending weld toes, or cleaning up cut profiles. It fits Type R quick-change disc holders, which are common on right-angle grinders used in light fabrication and sheet metal shops. Both professional fabricators and experienced tradespeople working with sheet goods will find this disc fits standard workflows without special adapters.
