Tru-maxx 69957323748 Quick-change Disc 1-1/2 in 50 Grit

Product Description

The TRU-MAXX 69957323748 is a quick-change abrasive disc designed for aggressive material removal on metal, weld seams, and surface prep applications. At 1-1/2 inches in diameter, it mounts to Type R and TR (Type III) quick-change tools without the need for separate hardware. The disc uses zirconia alumina abrasive at 50 grit, a coarse grade well suited for fast stock removal. A cloth backing with Y-weight construction gives it the rigidity to hold up under pressure. Maximum rated speed is 20,000 RPM. This disc is sold individually but requires a minimum order quantity of 100 units.

This disc fits grinding, blending, and weld dressing tasks in fabrication shops, maintenance environments, and field metalwork. The 1-1/2-inch format is commonly used in tight spaces and on contoured surfaces where larger discs cannot reach. The zirconia alumina grain self-sharpens during use, which extends disc life compared to aluminum oxide alternatives. The blue cloth backing and black button are standard visual identifiers for this disc type. Licensed tradespeople in welding, pipefitting, and general metalwork are the primary users of this product.

Installation Notes

Installation is performed by trade professionals in fabrication, pipefitting, or maintenance roles. Before mounting, confirm the tool spindle speed rating meets or exceeds 20,000 RPM and accepts Type R or TR (Type III) discs. Secure the disc fully onto the mandrel button before powering the tool. Always wear appropriate eye protection and follow ANSI B11 and OSHA 29 CFR 1910.215 abrasive wheel safety guidelines during use.
