Merit Abrasives 69957399648 Quick-change Disc 320 Grit 2in

Product Description

The MERIT ABRASIVES 69957399648 is a 2-inch coated quick-change abrasive disc designed for use with Power-Lock Type 2 (TS/Type II) handheld disc sanders. Built on a Y-weight 2-ply polyester backing, the disc delivers rigid support and a faster cut rate compared to lighter backing materials. The aluminum oxide abrasive grain is rated at 320 grit, placing it in the extra fine grade category, making it well suited for finish deburring, light cleaning, and detailed surface work. Maximum operating speed is 30,000 RPM. Each unit is sold individually, with a minimum order quantity of 100 pieces.

This disc is intended for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is a good fit for fabrication shops, maintenance technicians, and metalworkers who require consistent finish quality on difficult-to-machine alloys. The handheld disc sander application makes it practical for in-place deburring and detailing on fabricated assemblies or welded joints where bench grinding is not practical.
