Tru-maxx 69957323730 Quick-change Disc 3in 60 Grit

Product Description

The TRU-MAXX 69957323730 is a quick-change abrasive disc designed for grinding, blending, and surface preparation on metal and other industrial materials. It measures 3 inches in diameter and carries a 60-grit aluminum oxide abrasive, placing it in the medium-grade range suited for aggressive stock removal and weld seam blending. The disc uses a Type R attaching system for fast tool-free swaps on compatible random-orbit and die grinders. It is cloth-backed with an X-weight backing for added durability under load, and it is rated to a maximum of 20,000 RPM. Machinists, fabricators, and maintenance technicians are the primary users of this disc.

This disc is well suited for ferrous and non-ferrous metal work in fabrication shops, MRO environments, and field repair situations. The 60-grit cut makes it effective for removing mill scale, rust, paint, and light weld flash before finishing passes. The coated brown aluminum oxide grain is a general-purpose abrasive that holds up to moderate heat buildup during extended grinding cycles. The Type R quick-change mount reduces downtime between disc changes on production lines or during multi-step surface prep workflows. Each package contains one disc.

Installation Notes

Installation and disc changes must be performed with the grinder fully powered down and disconnected from the air supply or electrical source. Verify the tool spindle speed rating meets or exceeds 20,000 RPM before mounting this disc. Inspect the disc for cracks or damage before each use and discard any disc showing delamination or torn backing. Eye protection and appropriate PPE are required during all grinding operations per applicable OSHA and ANSI B11 guidelines.
