Merit Abrasives 69957399754 Quick-change Disc 80 Grit 1 in

Product Description

The MERIT ABRASIVES 69957399754 is a Type 1 Power-Lock quick-change disc designed for aggressive stock removal and weld blending on metal surfaces. At 1 inch in diameter, it mounts to handheld disc sanders using a Type P attaching system for fast, tool-free changes. The abrasive is 80-grit aluminum oxide on a rigid Y-weight 2-ply polyester backing, rated to 40,000 RPM. The special grain coating extends disc life and maintains a fast cut rate on moderately demanding grinding and finishing tasks. Licensed contractors and metal fabricators working on tight-access areas will find this disc sized for precision work.

This disc is suited for use on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. The coarse 80-grit grade makes it practical for initial stock removal, weld blending, and surface conditioning where speed of cut matters more than final finish. It is intended for use with handheld disc sanders in production, fabrication, and maintenance environments.
