Arc Abrasives 71-31663 Surface Conditioning Disc 3 in 40 Grit

Product Description

The ARC ABRASIVES 71-31663 is a 3-inch surface conditioning disc designed for edge grinding on metal surfaces. It features an extremely flexible backing paired with 100 percent cotton abrasive construction, making it well suited to contour work and tight edge profiles. At 40 grit, it delivers aggressive material removal while the flexible backing conforms to irregular surfaces without gouging. This disc is sold individually and is a standard consumable used by fabricators, welders, and metal finishing technicians working with cold rolled mild steel and stainless steel sheet.

This disc is intended for edge grinding applications on cold rolled mild steel and stainless steel sheet stock. The flexible construction allows it to follow curved and beveled edges without the stiffness associated with fiber or rigid resin-bonded discs. It is a practical choice for light deburring, blending, and surface prep work in fabrication shops, maintenance facilities, and field metalworking environments. The 3-inch diameter is compatible with small angle grinders and die grinders commonly used for detail work.
