Tru-maxx 66253291896 Mounted Point B91 60 Grit

Product Description

The TRU-MAXX 66253291896 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and other hard materials. This B91 flat cone shape point measures 5/8 inches thick and mounts on a 1/8 inch diameter shank that is 1-1/2 inches long. At 60 grit with a medium grade, it removes material efficiently while leaving a controlled surface finish. The aluminum oxide abrasive is well suited for ferrous metals and general-purpose grinding applications. Rated to a maximum of 61,110 RPM, it is compatible with standard die grinders and rotary tools used by machinists, fabricators, and maintenance technicians.

This mounted point is used in maintenance, repair, and fabrication settings where access to tight areas or contoured surfaces is required. The flat cone B91 geometry allows work in recessed bores, chamfers, and irregular profiles where a larger wheel cannot reach. It is a single-piece item sold with a minimum order quantity of 5 units, making it appropriate for shop stock or field repair kits. Typical applications include weld cleanup, port matching, mold finishing, and edge blending on steel, cast iron, and similar materials.

Installation Notes

This mounted point is installed by a machinist or maintenance technician using a die grinder or rotary tool with a matching 1/8 inch collet. Always verify the tool spindle speed does not exceed the 61,110 RPM maximum rating of the abrasive before operation. Inspect the mounted point for cracks or chips before each use and discard any damaged point immediately. Use appropriate eye protection and guards in accordance with applicable ANSI abrasive safety standards.
