Merit Abrasives 69957399608 Quick-change Disc 120 Grit

Product Description

The MERIT ABRASIVES 69957399608 is a coated quick-change abrasive disc designed for use with Power-Lock Type 2 (TS / Type II) attaching systems. Measuring 0.75 inches in diameter, this disc features 120-grit aluminum oxide on a rigid polyester backing, placing it in the fine-grade range. It is rated for a maximum of 40,000 RPM, making it suitable for high-speed rotary tools used in metal finishing, surface prep, and deburring applications. Licensed tradespeople and skilled technicians in metalworking, fabrication, and maintenance trades rely on this format for precision material removal in tight or confined areas.

This disc is suited for light material removal, blending, and finishing passes on metal surfaces. The small 0.75-inch diameter is especially useful in restricted-access areas where larger discs cannot reach. The rigid polyester backing provides consistent contact and controlled cut rate. It is sold individually but requires a minimum order quantity of 100 units, making it appropriate for shop stocking or fleet-level maintenance programs.

Installation Notes

Installation is performed by metalworking fabricators, maintenance technicians, and tool-and-die professionals. Before mounting, confirm the tool mandrel matches the TS (Type II) quick-change interface and verify the tool's no-load RPM does not exceed 40,000 RPM. Inspect the disc for damage before each use and discard any disc showing cuts, tears, or delamination. Follow applicable ANSI B7 safety standards and always use appropriate eye and face protection when operating abrasive tools.
