Merit Abrasives 69957399654 Quick-change Disc 80 Grit

Product Description

The MERIT ABRASIVES 69957399654 is a coated quick-change abrasive disc designed for use with Power-Lock Type 2 (TS/Type II) handheld disc sanders. The disc measures 3 inches in diameter and uses aluminum oxide abrasive at 80 grit, placing it in the medium-to-coarse cutting range for aggressive stock removal and surface preparation. It features a rigid, X-weight 2-ply cloth and polyester backing rated for up to 20,000 RPM, making it well-suited for deburring, cleaning, and detailing operations on metal surfaces. HVAC sheet metal fabricators, pipefitters, and general maintenance trades install this disc as part of routine surface prep and weld cleanup work.

This disc is appropriate for use on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. It mounts via a Type S attaching system compatible with standard TS quick-change disc holders on handheld disc sanders. Typical applications include deburring cut edges, cleaning weld beads, and light surface conditioning on fabricated metal components in both shop and field environments.
