Merit Abrasives 69957399643 Quick-change Disc 100 Grit 2 in

Product Description

The MERIT ABRASIVES 69957399643 is a 2-inch aluminum oxide quick-change abrasive disc designed for use with Power-Lock TS (Type II) Type S attachment systems on handheld disc sanders. Rated at 100 grit fine grade, this coated disc features a Y-weight 2-ply cloth and polyester backing that delivers a rigid, durable cutting surface. The aluminum oxide abrasive provides a faster cut rate and extended service life compared to standard single-ply backings. It is part of the R766 Series and is intended for deburring, cleaning, and surface detailing work on metal. The disc spins safely up to 30,000 RPM and weighs 0.001 pounds.

This disc is suited for metalworking applications in both shop and field environments. It is compatible with 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. Typical use cases include weld cleanup, edge deburring, and surface prep on fabricated metal components. It attaches via a Type S quick-change system, making tool-free disc swaps fast during production work. This disc is sold individually but carries a minimum order quantity of 100 units.
