Arc Abrasives 31662 Surface Conditioning Disc 3in 36 Grit

Product Description

The ARC ABRASIVES 31662 is a 3-inch Type R surface conditioning disc engineered for aggressive material removal on metal surfaces. Built with an extremely flexible backing and 100 percent cotton abrasive construction, this disc conforms closely to workpiece contours while maintaining consistent scratch patterns. At 36 grit, it is rated for coarse stock removal and is well suited for edge grinding and surface prep tasks where control and flexibility matter. Licensed trades and fabricators working with ferrous and non-ferrous sheet stock will find this disc a dependable consumable for production and repair work alike.

This disc is designed for edge grinding applications on cold rolled mild steel and stainless steel sheet. The flexible backing allows the disc to follow irregular edges and curved surfaces without gouging or loading, making it appropriate for both flat stock prep and contoured weld seam cleanup. It is sold individually and is intended for use in high-volume fabrication, metal finishing, and maintenance environments where 36-grit cut rates are required.

Installation Notes

Installation of Type R quick-change discs requires a compatible Type R backup pad; confirm pad size matches the 3-inch disc diameter before mounting. Power down and disconnect the grinder from its power source before changing discs. Inspect the disc for tears or delamination prior to use and do not exceed the RPM rating marked on the disc or backup pad. Eye protection and appropriate PPE are required per standard shop safety practices.
