Merit Abrasives 69957399744 Quick-change Disc 120 Grit

Product Description

The MERIT ABRASIVES 69957399744 is a quick-change coated abrasive disc designed for use with Power-Lock Type 1 attachment systems. At 3/4 inch in diameter, this disc is built for precision grinding, deburring, and surface blending in tight or confined areas. It features an aluminum oxide abrasive grain at 120 grit, placing it in the fine grade category for controlled material removal and surface finishing. The polyester backing provides a rigid platform that maintains disc geometry under load. Rated to 40,000 RPM, it is suited for high-speed die grinders and rotary tools used in metal fabrication, maintenance, and repair work.

This disc fits applications where a small-diameter, quick-change abrasive is needed for spot finishing, weld blending, or edge work on metal surfaces. The Type P attaching system allows rapid disc changes without additional tools, reducing downtime during production or repair operations. Typical users include metalworkers, welders, maintenance technicians, and fabrication shop personnel who require consistent, repeatable results on ferrous and non-ferrous materials. Sold individually with a minimum order quantity of 100 units.
