Tru-maxx 69957323760 Quick-change Disc 3 in 50 Grit

Product Description

The TRU-MAXX 69957323760 is a quick-change abrasive disc designed for high-speed material removal on metal and other hard surfaces. At 3 inches in diameter and 50 grit, it falls in the coarse grade range, making it well suited for weld blending, rust removal, surface prep, and deburring. The disc is constructed with a zirconia alumina abrasive on a cloth backing with a Y-weight backing for added durability under aggressive grinding conditions. Rated to 20,000 RPM, it uses a Type R attaching system for fast tool-free disc changes. The disc is blue in color with a black button.

This disc is used in metal fabrication shops, maintenance and repair operations, and field service work where fast stock removal is needed. Typical applications include weld seam grinding, surface conditioning before coating, and edge preparation on steel and stainless. It mounts to any Type R compatible right-angle grinder or die grinder with a quick-change mandrel. This disc is sold individually but is available in a minimum order quantity of 50 units, making it appropriate for shop stock or job-lot purchasing.

Installation Notes

Installation requires a Type R compatible quick-change mandrel; confirm mandrel condition before mounting. Always verify the tool spindle speed does not exceed the 20,000 RPM disc rating before operation. Wear appropriate PPE including eye protection and gloves when mounting or operating abrasive discs. Inspect the disc for damage or delamination before each use and discard any disc showing signs of wear through to the backing.
