Arc Abrasives 71-31466 Quick Lok Disc Type S 3in Grit 80 50pk

Product Description

The ARC ABRASIVES 71-31466 is a 3-inch Quick Lok abrasive disc in Type S configuration, sold in boxes of 50. It uses a mechanical locking button center that mounts and locks the disc onto a compatible random orbital or die grinder tool with a simple twist. The disc runs a Grit 80 abrasive blend described as self-sharpening, making it a cost-effective alternative to full ceramic abrasive discs. It is engineered for stock removal and surface conditioning on mild steel and is a practical volume-purchase option for shops and field techs who run high disc turnover.

This disc is suited for metal fabrication, light grinding, weld blending, and surface prep work on mild steel in both shop and jobsite environments. The 3-inch diameter fits compact die grinders and right-angle tools equipped with a Type S Quick Lok backer pad. The Grit 80 cut makes it appropriate for aggressive material removal where a finer finish pass will follow. It is commonly used by ironworkers, fabricators, maintenance mechanics, and industrial tradespeople.
