Tru-maxx 66253291667 Mounted Point W143 60 Grit 1/8 in

Product Description

The TRU-MAXX 66253291667 is an aluminum oxide mounted point in the W143 cylinder shape, designed for precision grinding, deburring, and surface blending on metal and hard materials. With a 60-grit medium grade abrasive, this mounted point removes material efficiently while leaving a workable surface finish. The 1/8-inch shank diameter fits standard die grinders and rotary tools, making it a practical choice for machinists, fabricators, and tool and die professionals who need consistent abrasive performance in tight or contoured areas. The point is rated to 105,000 RPM, supporting high-speed rotary tool use in production and maintenance applications.

This mounted point is suited for use in metalworking, weld blending, mold and die work, and general deburring tasks on steel, cast iron, and other ferrous materials. The cylinder profile allows flat-face and side grinding in slots, cavities, and interior surfaces that larger wheels cannot reach. It is commonly used in machine shops, fabrication facilities, and maintenance environments where precision hand grinding is required.

Installation Notes

Mounted points must be installed in a die grinder or rotary tool collet rated for the shank diameter before use. Always confirm the tool spindle speed does not exceed the 105,000 RPM rating marked on this product. Inspect the point for cracks or damage before each use and discard any damaged abrasive immediately. Eye protection and appropriate PPE are required during all grinding operations per applicable safety standards.
