Merit Abrasives 69957399701 Quick-change Disc 150 Grit 1.5 in

Product Description

The MERIT ABRASIVES 69957399701 is a coated quick-change abrasive disc designed for use with Power-Lock Type R attachment systems. Built on a rigid polyester backing with a Y-weight designation, this disc carries aluminum oxide abrasive grain at 150 grit, placing it in the very fine grade category. It measures 1.5 inches in diameter and is rated for a maximum of 30,000 RPM, making it suitable for high-speed rotary tools and die grinders. The brown coated surface and black button are consistent with the Merit R766 series. This disc is sold individually with a minimum order quantity of 100 units.

This disc is suited for light material removal, blending, and surface finishing in tight or confined areas where a small-diameter abrasive is required. The 1.5-inch diameter makes it practical for detail work on metal surfaces in fabrication, maintenance, and repair applications. It is commonly installed by machinists, maintenance technicians, metalworkers, and industrial trade professionals who rely on quick-change tooling for efficient abrasive swaps during production or service work.
