Tru-maxx 69957323820 Quick-change Disc 3in 50 Grit

Product Description

The TRU-MAXX 69957323820 is a 3-inch quick-change abrasive disc designed for aggressive material removal in grinding and blending applications. It uses aluminum oxide abrasive at a coarse 50 grit rating, making it well suited for weld grinding, surface prep, and stock removal on ferrous and non-ferrous metals. The disc features a Type S quick-change attaching system for fast, tool-free mounting. A heavy X-weight cloth backing provides durability under high-load conditions. Rated to 20,000 RPM, it handles sustained use on die grinders and right-angle grinders without delamination or glazing. Fabricators, welders, and maintenance technicians are the primary users of this disc.

This disc is intended for metal fabrication shops, maintenance and repair operations, and general industrial use. The coarse 50 grit cut makes it most effective on initial weld dressing, scale removal, and surface conditioning where a finer finish is not required. The Type S attachment makes it compatible with standard quick-change mandrels commonly found in production grinding setups. Sold individually, with a minimum order quantity of 50 units per order.
