Tru-maxx 66253292107 Mounted Point 60 Grit W185 1/4 in Shank

Product Description

The TRU-MAXX 66253292107 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal workpieces. It features a W185 cylinder shape with a 0.5 inch head thickness, a 0.25 inch diameter shank, and a 1.5 inch shank length for use in die grinders and rotary tools. The abrasive is medium grade at 60 grit, suitable for moderate material removal and surface blending. Rated to a maximum of 44,470 RPM, it handles aggressive grinding cycles without excessive wear. Machinists, tool and die makers, and fabricators use this type of mounted point for internal bore work, weld cleanup, and contour grinding.

This mounted point is suited for use in machine shops, fabrication facilities, and maintenance environments where controlled grinding access is needed in tight spaces or recessed areas. The W185 cylinder profile provides flat-face and side-grinding capability, making it practical for squaring shoulders, cleaning up castings, and finishing interior surfaces. It is compatible with standard 0.25 inch collet die grinders and flex-shaft rotary tools commonly found in industrial and trade settings.

Key Features

• W185 cylinder shape for flat-face and side-grinding applications
• 60 grit medium grade aluminum oxide abrasive for balanced stock removal and surface finish
• 0.25 inch shank diameter fits standard die grinder collets
• 1.5 inch shank length provides reach into recessed bores and confined areas
• Maximum rated speed of 44,470 RPM for use with high-speed rotary tools
• Pink aluminum oxide composition offers consistent cut rate on ferrous metals

Compatibility

Designed for use with die grinders, rotary tools, and flex-shaft machines fitted with a standard 0.25 inch collet. Suitable for grinding ferrous metals, castings, and hardened steel in industrial and maintenance applications.

Installation Notes

This mounted point is installed by a machinist or fabricator into a die grinder or rotary tool with a matching 0.25 inch collet. Always verify the tool spindle RPM does not exceed the 44,470 RPM maximum rating before operation. Secure the shank fully into the collet and tighten to the tool manufacturer specification before running. Wear appropriate eye protection and ensure workpiece is secured before grinding.
