Merit Abrasives 69957399686 Quick-change Disc 80 Grit 1 in

Product Description

The MERIT ABRASIVES 69957399686 is a 1-inch aluminum oxide quick-change disc designed for use with TR (Type III) and Type R attaching systems on handheld disc sanders. Running at a maximum of 40,000 RPM, this coated abrasive features an 80-grit medium-grade cut on a rigid, X-weight 2-ply cloth and polyester backing. The brown disc is built for deburring, cleaning, and detailing work on stainless steel, aluminum, brass, bronze, titanium, and both soft and hard carbon steels. Licensed tradespeople and metalworking professionals rely on this disc for consistent material removal in tight or contoured areas where larger abrasives cannot reach.

This disc is intended for use on handheld disc sanders in both shop and field environments. Its 1-inch diameter makes it well suited for detailed deburring and surface preparation on 300 and 400 series stainless steel, aluminum, brass, bronze, titanium, and soft and hard carbon steels. The quick-change Power-Lock Type 3 interface allows fast disc swaps without additional tooling, reducing downtime during multi-step finishing operations. It fits into maintenance, fabrication, and surface preparation workflows across HVAC, plumbing, and general metalworking trades.
