Merit Abrasives 69957399706 Quick-change Disc 36 Grit

Product Description

The MERIT ABRASIVES 69957399706 is a coated abrasive quick-change disc designed for aggressive material removal on metal surfaces. Built on an X-weight, 2-ply cloth and polyester backing, this rigid disc handles the high stress of handheld disc sander applications without delaminating or glazing over. At 36 grit, it falls in the extra coarse range, making it well-suited for deburring, surface cleaning, and stock removal. The Power-Lock Type 3 (TR/Type III) attaching system allows fast one-handed disc changes, reducing downtime during production or service work. Maximum rated speed is 30,000 RPM. Disc diameter is 2 inches.

This disc is intended for use on a broad range of metals encountered in trade and fabrication work. Rated material applications include 300 series stainless, 400 series stainless, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It fits handheld disc sanders equipped with a TR (Type III) or Type R quick-change arbor. Typical use cases include weld prep, deburring machined parts, cleaning heat-affected zones, and detailing stainless steel components in HVAC, plumbing, and light fabrication settings. Sold individually; minimum order quantity is 100 units.
