Tru-maxx 66253291882 Mounted Point W217 60 Grit 1/4 in Shank

Product Description

The TRU-MAXX 66253291882 is a W217 cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on metal and hard materials. It is constructed from aluminum oxide abrasive with a medium grade and 60 grit rating, making it well suited for moderate material removal and smoothing passes. The 0.375 inch thick head is mounted on a 0.25 inch diameter shank that is 1.5 inches long, providing reach into bores, cavities, and tight workpiece profiles. This mounted point runs at a maximum of 37,890 RPM and is compatible with rotary tools, die grinders, and flexible shaft machines. Machinists, tool and die workers, and maintenance technicians use this type of abrasive for finishing internal surfaces and cleaning up weld areas.

This mounted point is used in both production shop and maintenance environments where controlled abrasive action is required on ferrous metals, cast iron, and similar hard materials. Its cylinder geometry makes it a practical choice for flat-bottom grinding in slots, pockets, and stepped bores. It is sold individually and is a standard consumable stocked by machine shops, fabrication facilities, and industrial maintenance operations. The 0.25 inch shank fits standard die grinder collets found in most shop environments.

Installation Notes

This mounted point is installed by a machinist or maintenance technician using a die grinder or rotary tool with a matching 0.25 inch collet. Ensure the tool is de-energized and unplugged before installing or changing the mounted point. Tighten the collet securely and verify the point is running true before engaging the workpiece. Never exceed the 37,890 RPM maximum speed rating marked for this abrasive.
