Merit Abrasives 69957399712 Quick-change Disc 120 Grit 2in

Product Description

The MERIT ABRASIVES 69957399712 is a 2-inch coated quick-change disc designed for use with Power-Lock Type R and TR (Type III) attachment systems. Built on a Y-weight 2-ply polyester and cloth backing rated X-weight, it delivers a rigid, durable platform for aggressive stock removal at up to 30,000 RPM. The aluminum oxide abrasive is bonded in a coated configuration that extends disc life and maintains a faster cut rate compared to lighter-backed alternatives. At 120 grit, this disc sits in the fine range and is suited for deburring, surface cleaning, and detail finishing work on metal substrates. Installation and use require a compatible handheld disc sander or quick-change tool with a Type R or TR arbor.

This disc is engineered for metalworking applications across a range of ferrous and non-ferrous materials including 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is well suited for maintenance, fabrication, and finishing tasks where controlled material removal and surface quality matter. The rigid backing keeps the abrasive flat against the workpiece, making it effective for deburring weld seams, cleaning oxide scale, and refining contours on fabricated parts. Minimum order quantity is 100 units; each package contains 1 disc.
