Merit Abrasives 69957399715 Quick-change Disc 240 Grit

Product Description

The MERIT ABRASIVES 69957399715 is a 2-inch coated quick-change disc designed for use with Power-Lock Type R attaching systems on handheld disc sanders. The abrasive material is aluminum oxide at 240 grit, rated Very Fine grade, making it suitable for precision finishing work including deburring, cleaning, and detailing. The disc uses a Y-weight 2-ply polyester backing, classified as X-weight and rigid, which supports faster cut rates and extended service life compared to lighter backing materials. Maximum operating speed is 30,000 RPM. This disc is sold individually with a minimum order quantity of 100 units, making it a standard consumable for trade and shop environments.

This disc is suited for finishing operations on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The aluminum oxide abrasive and rigid polyester backing handle both ferrous and non-ferrous metals effectively. Typical applications include weld cleanup, surface prep, light deburring, and part detailing in fabrication shops, maintenance facilities, and field service environments. Handheld disc sanders with a Type R quick-change arbor are the intended machine platform.
