Arc Abrasives 31661 Surface Conditioning Disc 3in 24 Grit

Product Description

The ARC ABRASIVES 31661 is a 3-inch aluminum oxide resin fiber surface conditioning disc designed for aggressive material removal and surface prep work. Running at 24 grit, this coarse disc cuts fast and is built for quick change mounting systems, making tool changes efficient during production grinding and blending operations. It is suited for metalworking trades including fabricators, welders, and maintenance technicians who need consistent stock removal on steel, stainless, and other hard metals. The aluminum oxide abrasive delivers reliable cut rate and edge durability across high-contact applications.

This disc is intended for use in surface preparation, weld blending, rust and scale removal, and light deburring on metal workpieces. The quick change design is compatible with QLOK-R style mandrels, allowing tool-free disc swaps on angle grinders and die grinders. It fits well into shop floor workflows where downtime between disc changes needs to stay low. The 24 grit coarseness makes it most appropriate for initial surface conditioning passes rather than finish work.

Installation Notes

Installation is performed by metalworking and maintenance trades using standard angle grinders or die grinders equipped with a compatible QLOK-R mandrel. Always power down and disconnect the tool from its power source before mounting or removing the disc. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM rating of the tool or disc.
