Tru-maxx 69957323735 Quick-change Disc 3 in 180 Grit

Product Description

The TRU-MAXX 69957323735 is a quick-change abrasive disc designed for surface preparation, blending, and finishing applications in metalworking and fabrication environments. Built on a cloth backing with an X-weight designation, this disc carries aluminum oxide abrasive at 180 grit, placing it in the very fine grade range. It attaches via a Type R quick-change system for tool-free swaps between grits. Rated to 20,000 RPM, it suits high-speed right-angle die grinders and finishing tools commonly used by machinists, welders, pipefitters, and maintenance technicians working on metal surfaces.

This disc is suited for fine finishing passes on ferrous and non-ferrous metals, deburring edges, and blending weld seams where a finer surface finish is required. The 3-inch diameter fits compact quick-change mandrels used in tight clearance work, including tube interiors, around flanges, and in confined joint areas. The coated brown aluminum oxide abrasive provides consistent cut-rate at lighter pressure, making it appropriate for final-stage work before inspection or coating application.

Key Features

Compatibility

Designed for use with Type R quick-change mandrels on right-angle die grinders and finishing tools accepting 3-inch quick-change discs.

Installation Notes

Installation is performed by pressing the disc onto a compatible Type R mandrel until the locking mechanism seats fully. Always confirm the grinder spindle speed does not exceed the 20,000 RPM disc rating before operation. Inspect the disc for damage or delamination before each use and discard any disc showing cracks, tears, or backing separation. Eye protection and appropriate PPE are required during abrasive disc operation per standard shop safety practice.
