Merit Abrasives 69957399621 Quick-change Disc 150 Grit 1 in

Product Description

The MERIT ABRASIVES 69957399621 is a coated quick-change abrasive disc designed for use with Power-Lock Type 2 (TS Type II) quick-change systems. It measures 1 inch in diameter and uses aluminum oxide abrasive at 150 grit, placing it in the very fine grade range. The polyester cloth backing is rated Y-weight for rigidity, making it well-suited for precision finishing, light deburring, and surface blending on metal. The disc is rated to a maximum of 40,000 RPM. It is installed and used by machinists, fabricators, maintenance technicians, and metalworking tradespeople who require consistent fine-grit performance in tight-access grinding and finishing applications.

This disc fits compact quick-change mandrels used in die grinders and similar rotary tools. At 1 inch in diameter, it is suited for internal diameter work, weld finishing in confined areas, and detailed surface preparation on metal components. The aluminum oxide abrasive construction handles ferrous and non-ferrous metals effectively. The silver button attaches to Type S mandrels, providing a secure, tool-free disc change during continuous production or field service work. This SKU is sold individually with a minimum order quantity of 100 units.
