Tru-maxx 69957323761 Quick-change Disc 3 in 60 Grit

Product Description

The TRU-MAXX 69957323761 is a quick-change abrasive disc designed for fast material removal and surface preparation in metalworking and fabrication applications. The disc measures 3 inches in diameter and cuts with 60-grit zirconia alumina abrasive, placing it in the medium grade range. Zirconia alumina is a self-sharpening abrasive that holds up well under moderate to heavy grinding pressure, making it a practical choice for weld blending, deburring, and stock removal on ferrous and non-ferrous metals. The cloth backing provides flex and durability, and the disc is rated to a maximum of 20,000 RPM.

This disc is suited for use in fabrication shops, maintenance environments, and field metalwork where a Type R quick-change attachment system is in use. The Type R interface allows for tool-free disc swaps directly onto compatible right-angle die grinders and finishing tools. The blue coated face and black button are standard identifiers for this disc format. It is typically installed by machinists, welders, pipefitters, and general maintenance trades working on metal surface conditioning tasks.

Installation Notes

Install onto a Type R mandrel that is properly seated in a right-angle die grinder rated for the disc RPM. Always confirm the tool speed does not exceed the 20,000 RPM disc rating before operation. Wear appropriate eye protection and gloves during disc changes and grinding. Inspect the disc for damage or delamination before each use and discard any disc showing signs of wear through to the backing.
