Tru-maxx 66261132867 Quick-change Disc 3 in Aluminum Oxide

Product Description

The TRU-MAXX 66261132867 is a 3-inch non-woven aluminum oxide quick-change disc designed for surface conditioning, blending, and finishing on metal and fabricated components. Rated at 18,000 RPM and finished in a maroon color indicating medium grade, this disc mounts via a TR (Type III) attaching system for fast, tool-free changeovers on compatible right-angle grinders and die grinders. It is sold individually and is intended for professional metalworking, fabrication, and maintenance environments where consistent surface finish results are required at production pace.

This disc is suited for deburring, surface prep, light stock removal, and blending weld seams on steel, stainless steel, aluminum, and similar substrates. The non-woven construction conforms to irregular surfaces and resists loading, making it a practical choice for finishing passes in fabrication shops, maintenance departments, and field metalwork. It is compatible with Type R and TR quick-change systems, which are widely used across grinder and finishing tool platforms in the trades.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source. Inspect the disc for damage before mounting and confirm the spindle speed of the tool does not exceed the 18,000 RPM rating of the disc.
