Tru-maxx 69957323742 Quick-change Disc 1 in 80 Grit

Product Description

The TRU-MAXX 69957323742 is a quick-change abrasive disc designed for high-speed material removal and surface preparation on metal, welds, and fabricated components. At 1 inch in diameter with an 80-grit zirconia alumina abrasive, this disc delivers medium-grade cutting action suited to grinding, blending, and deburring tasks. The cloth backing provides flexibility and durability under load, and the zirconia alumina grain self-sharpens during use to maintain a consistent cut rate. Rated to 20,000 RPM, it is built for use with pneumatic and electric quick-change tools common in fabrication and maintenance environments.

This disc is sized for tight-access grinding and blending work where larger discs cannot reach. Typical applications include weld blending, edge deburring, and surface conditioning on steel and other ferrous metals. The Type R attaching system provides fast disc swaps without tools, reducing downtime during production runs or repair work. The blue cloth-backed construction holds up to moderate heat and pressure, making it appropriate for sustained use on a die grinder or similar rotary tool in fabrication shops, maintenance facilities, and industrial service settings.

Compatibility

Designed for use with Type R quick-change mandrels on pneumatic or electric die grinders and rotary tools that accept 1 inch quick-change abrasive discs.

Installation Notes

Installation requires a Type R quick-change mandrel mounted securely in the tool chuck. Verify the tool's rated RPM meets or exceeds the disc's 20,000 RPM maximum before use. Always wear appropriate eye protection and ensure the workpiece is secured before engaging the disc. Do not exceed the maximum RPM rating or use the disc on a tool with a damaged or worn mandrel.
