Merit Abrasives 69957399653 Quick-change Disc 3 in 60 Grit

Product Description

The MERIT ABRASIVES 69957399653 is a coated abrasive quick-change disc designed for use with Power-Lock Type 2 (TS Type II) handheld disc sanders. The disc measures 3 inches in diameter and cuts at 60 grit, placing it in the medium-to-coarse range for aggressive material removal and surface conditioning. Its aluminum oxide abrasive grain is bonded to a rigid, Y-weight, 2-ply cloth and polyester backing that holds up under sustained grinding pressure. Rated to 20,000 RPM, this disc suits demanding deburring, cleaning, and detailing work on stainless steel, carbon steel, aluminum, brass, bronze, titanium, and similar metals. It is installed and used by metalworkers, fabricators, and maintenance technicians.

This disc is part of the Merit R766 series and is intended for handheld disc sander applications where a Type S or TS quick-change attaching system is used. It is well suited for deburring, surface cleaning, and detailing on 300 and 400 series stainless steel, soft and hard carbon steels, aluminum, brass, bronze, and titanium. The rigid backing and medium grit combination make it a practical starting specification for light weld cleanup and surface prep on soft metals in fabrication and maintenance settings. Each package contains 1 disc, sold with a minimum order quantity of 50 units.
