Arc Abrasives 71-31465 Quick Lok Disc Type S 3in Grit 60

Product Description

The ARC ABRASIVES 71-31465 is a 3-inch Quick Lok abrasive disc designed for fast material removal on mild steel and similar metals. Sold in boxes of 50, this Type S disc uses a mechanical locking button center that seats and locks onto compatible quick-change tools with a simple twist. The 60-grit ceramic-blend grain is self-sharpening, meaning fresh cutting edges are continuously exposed as the disc wears. This design delivers consistent cut rates through the life of the disc without the full cost of 100-percent ceramic abrasive products. Fabricators, welders, and metal finishing technicians are the primary users.

This disc is suited for grinding and blending operations on mild steel in both shop and field environments. The 3-inch diameter fits standard quick-change disc holders that accept Type S locking attachments, making it a practical choice for angle grinders and die grinders used in light fabrication, weld prep, and surface conditioning work. The 60-grit designation positions it for aggressive stock removal rather than fine finishing. Box quantity of 50 units supports production workflows where disc turnover is high.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or with the battery removed. Align the disc center button with the tool holder, press in, and twist to lock before verifying the disc is fully seated. Inspect the disc for damage before each use and do not exceed the maximum RPM rating of the tool or the disc. Eye protection and appropriate PPE are required when operating abrasive grinding equipment.
