Tru-maxx 69957323831 Quick-change Disc 1 in 50 Grit

Product Description

The TRU-MAXX 69957323831 is a 1-inch coated quick-change abrasive disc designed for rapid material removal on metal, weld seams, and surface prep applications. Built with a zirconia alumina abrasive grain and a cloth backing rated Y-weight, this disc delivers the durability and cut rate that coarse-grit work demands. It runs at a maximum of 20,000 RPM and attaches via a Type S (TS Type II) quick-change system, making tool-free disc swaps fast in production environments. The blue disc color provides easy visual identification on the shop floor. Sold individually, with a minimum order quantity of 100 units.

This disc is suited for metalworking, fabrication, and maintenance applications where a small-diameter coated disc is required on a right-angle or die grinder fitted with a Type S quick-change mandrel. Common tasks include weld blending, deburring, edge chamfering, and light stock removal on ferrous and non-ferrous metals. The coarse 50-grit cut makes it most appropriate for aggressive surface conditioning rather than finishing passes. It is typically used by machinists, fabricators, maintenance mechanics, and industrial tool-and-die professionals in shop or field settings.

Installation Notes

Installation requires a Type S quick-change mandrel rated for the disc diameter and RPM. Verify that the grinder spindle speed does not exceed the 20,000 RPM disc rating before mounting. Always power down and disconnect the tool from its power source before mounting or removing discs. Wear appropriate PPE including eye protection and gloves when operating coated abrasives.
