Arc Abrasives 71-31664 Surface Conditioning Disc 3 in 50 Grit

Product Description

The ARC ABRASIVES 71-31664 is a 3-inch surface conditioning disc designed for edge grinding on metal surfaces. It combines an extremely flexible backing with a 100 percent cotton abrasive construction to conform to workpiece edges during material removal. At 50 grit, this disc is suited for moderate stock removal and surface blending on cold rolled mild steel and stainless steel sheet. It is sold individually and is a standard choice for metal fabrication technicians, welders, and finishing tradespeople working with sheet metal components.

This disc is intended for edge grinding applications on cold rolled mild steel and stainless steel sheet stock. The flexible cotton-backed construction allows the disc to follow contours and edges more closely than rigid abrasive formats, making it practical for deburring, blending weld seams, and preparing edges before finishing operations. It fits standard angle grinder and disc tool setups common in sheet metal fabrication and light industrial environments.
