Tru-maxx 69957323739 Quick-change Disc 1 Inch 40 Grit

Product Description

The TRU-MAXX 69957323739 is a 1-inch quick-change abrasive disc designed for use with Type R and TR attaching systems. It features a zirconia alumina abrasive material bonded to a cloth backing, making it well suited for aggressive material removal on metal surfaces. The coarse 40-grit rating enables fast stock removal on welds, burrs, and surface scale. Rated to a maximum of 20,000 RPM, this disc is built for use with high-speed rotary tools common in fabrication, maintenance, and metalworking applications. The blue disc face and black button are standard identifiers for this product line.

This disc is intended for use in metal fabrication shops, manufacturing facilities, and maintenance environments where rapid surface conditioning or weld blending is required. The Type R quick-change interface allows fast disc swaps without tools, reducing downtime during extended grinding or finishing operations. It is appropriate for use on ferrous and non-ferrous metals in both bench and portable tool setups. Trades that commonly use this disc include sheet metal workers, pipefitters, welders, and maintenance mechanics.
