Merit Abrasives 69957399629 Quick-change Disc 60 Grit

Product Description

The MERIT ABRASIVES 69957399629 is a 1.5-inch quick-change coated abrasive disc designed for use with Power-Lock Type S attachment systems on handheld disc sanders. Built on a rigid, X-weight, 2-ply cloth and polyester backing, this 60-grit aluminum oxide disc delivers consistent material removal for deburring, cleaning, and detailing operations. The medium-grit aluminum oxide abrasive cuts efficiently across a broad range of metals, and the coated construction resists loading during extended use. Maximum rated speed is 30,000 RPM. Sold individually with a minimum order quantity of 100 units, making it suited for shop supply and maintenance program stocking.

This disc is intended for metalworking applications in light fabrication, maintenance, and finishing environments. It is rated for use on 300 series stainless steel, 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The Type S Power-Lock attachment provides a secure, tool-free disc change on compatible handheld disc sanders, reducing downtime during high-volume finishing work. Typical users include welders, pipefitters, fabricators, and maintenance mechanics who require a reliable small-diameter disc for tight-clearance deburring and surface prep.

Installation Notes

Installation is performed by pressing the disc onto a compatible Type S Power-Lock mandrel until the locking mechanism engages — no tools required. Before mounting or removing the disc, ensure the tool is powered off and unplugged or the air supply is disconnected. Verify that the tool's rated no-load RPM does not exceed the 30,000 RPM maximum disc rating before operation. Inspect the disc for damage before each use and discard any disc showing tears, cracks, or delamination.
