Merit Abrasives 69957399738 Quick-change Disc 36 Grit

Product Description

The MERIT ABRASIVES 69957399738 is a quick-change abrasive disc designed for use with Power-Lock Type 1 (Type P) attachment systems. It measures 0.75 inches in diameter and carries a 36-grit aluminum oxide abrasive coating, placing it in the very coarse grade range. The polyester backing is rigid and rated for a maximum of 40,000 RPM, making it suitable for high-speed grinding, weld removal, and surface preparation tasks. The disc is brown in color with a black button and is sold individually with a minimum order quantity of 100 units. Metal fabricators, welders, and general maintenance trades are the primary users.

This disc is suited for aggressive material removal on metal surfaces in both shop and field applications. The small 0.75-inch diameter makes it practical for tight-radius work, contoured surfaces, and confined areas where larger discs cannot reach. The coated aluminum oxide abrasive performs well on ferrous metals, making it a common choice for deburring, blending, and light stock removal. It fits tools equipped with a Power-Lock Type P quick-change mandrel, which allows fast disc swaps without additional hardware.
