Arc Abrasives 71-31662 Surface Conditioning Disc 3in 36G

Product Description

The ARC ABRASIVES 71-31662 is a 3-inch surface conditioning disc engineered for edge grinding on metal sheet stock. It features an extremely flexible backing paired with 100 percent cotton abrasive construction, giving it the conformability needed to follow contours and edges without loading or gouging the base material. At 36 grit, this disc removes material aggressively while leaving a consistent scratch pattern suitable for follow-on finishing steps. Fabricators and metalworkers install this disc on right-angle grinders and die grinders for fast, controlled stock removal along sheared or cut edges.

This disc is designed for edge grinding applications on cold rolled mild steel and stainless steel sheet. The flexible cotton backing allows the disc to wrap edges cleanly, making it well suited for deburring, blending weld seams, and prepping cut edges before finishing or coating. The 36-grit rating handles heavier material removal tasks where coarser conditioning is required prior to progressing through finer abrasive stages. Typical applications include light fabrication shops, maintenance and repair operations, and sheet metal work in industrial and commercial settings.

Installation Notes

Installation should be performed by a qualified fabricator or grinding equipment operator following the tool manufacturer's mounting instructions. Always power down and disconnect the grinder before mounting or changing discs. Confirm the disc speed rating meets or exceeds the tool's no-load RPM before operation. Wear appropriate PPE including face shield, gloves, and hearing protection during use.
