Arc Abrasives 71-31451 Surface Conditioning Disc 40 Grit 2 in

Product Description

The ARC ABRASIVES 71-31451 is a 2-inch Type S quick-lock surface conditioning disc designed for aggressive material removal and surface prep on metal, composites, and other substrates. Running at 40 grit, this disc is built for coarse conditioning work including weld blending, rust removal, and scale cleanup. The Predator line uses an open-web abrasive construction that resists loading and maintains consistent cut rate through the life of the disc. These discs are sold in a box of 100 and are a standard consumable for angle grinder setups equipped with a quick-lock mandrel.

These discs are used across metal fabrication, maintenance and repair, and light industrial applications where surface prep speed matters. The Type S quick-lock attachment system mounts directly to compatible quick-lock mandrels without tools, making disc changes fast during production or field work. The 40-grit rating makes this disc suited for initial conditioning passes, heavy oxidation removal, and prep before coating or finishing operations. Licensed tradespeople in welding, pipefitting, and general mechanical trades regularly use this disc type as a standard consumable.
