Arc Abrasives 71-31666 Surface Conditioning Disc 3 in 80 Grit

Product Description

The ARC ABRASIVES 71-31666 is a 3-inch surface conditioning disc designed for edge grinding on cold rolled mild steel and stainless steel sheet. Built with an extremely flexible backing and a 100 percent cotton abrasive construction, it conforms to contours and irregular edges without gouging or loading the work surface. At 80 grit, it delivers an aggressive cut that removes burrs, scale, and surface irregularities efficiently. Fabricators, metalworkers, and maintenance technicians working with sheet metal stock will find this disc suited to deburring, blending, and light surface prep tasks where disc flexibility is critical to consistent contact.

This disc is intended for edge grinding applications on cold rolled mild steel and stainless steel sheet in fabrication shops, light manufacturing environments, and field maintenance settings. The flexible cotton-backed construction makes it particularly effective where a rigid disc would chatter or skip on formed edges and thin sheet profiles. It is sold individually and intended for use with a compatible 3-inch disc grinder or right-angle grinder fitted with an appropriate backing pad.
