Tru-maxx 69957323728 Quick-change Disc 3 in 50 Grit

Product Description

The TRU-MAXX 69957323728 is a Type R quick-change abrasive disc designed for surface preparation, blending, and material removal in metalworking and fabrication applications. The disc measures 3 inches in diameter and features a 50-grit aluminum oxide abrasive bonded to a cloth backing with an X-weight designation, providing durability under aggressive grinding conditions. A black Type R center button allows for rapid disc changes on compatible quick-change holders without tools. The coated brown disc construction is suited for use on ferrous and non-ferrous metals. This product is sold individually and is intended for use by machinists, fabricators, and maintenance technicians working with angle grinders or die grinders fitted with a Type R mandrel.

This disc is appropriate for coarse stock removal, weld blending, deburring, and surface conditioning on flat and contoured metal workpieces. The 50-grit coarse grade makes it well suited for initial material removal passes rather than fine finishing work. It is commonly used in job shops, maintenance and repair operations, and light manufacturing environments. The cloth backing and aluminum oxide abrasive combination handles moderate to high pressure applications without premature breakdown. Sold as a single disc with a minimum order quantity of 50 units.
