Merit Abrasives 69957399642 Quick-change Disc 80 Grit

Product Description

The MERIT ABRASIVES 69957399642 is a 2-inch aluminum oxide quick-change disc designed for use with Power-Lock Type 2 (TS Type II) and Type S attaching systems. Built on an X-weight, 2-ply cloth and polyester backing, this rigid disc delivers consistent cut rate and durability under demanding deburring, cleaning, and detailing applications. The 80-grit medium-grade abrasive surface is rated to 30,000 RPM, making it suitable for handheld disc sander use across a wide range of metals. The coated aluminum oxide construction resists loading and maintains cutting action on both ferrous and non-ferrous workpieces.

This disc is engineered for use on 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It fits into the MERIT R766 series and is well suited for light material removal, surface preparation, and weld cleanup tasks where a controlled, consistent finish is required. Typical users include fabricators, maintenance technicians, and metalworkers operating handheld disc sanders in shop or field environments.
