Tru-maxx TM-153BE8RD1 Mounted Point W153 120 Grit

Product Description

The TRU-MAXX TM-153BE8RD1 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing in metalworking and fabrication applications. Built with aluminum oxide grain bonded in a vitrified matrix at a hard density, this mounted point delivers consistent stock removal and a fine finish at 120 grit. The 3/16 inch diameter head is 3/8 inch thick and mounts on a 1-1/2 inch shank, giving the user reach into bores, cavities, and contoured workpiece geometry. It is rated to 80,850 RPM for use with die grinders and rotary tools.

This mounted point is suited for tool-and-die work, mold finishing, weld cleanup, and internal bore grinding on ferrous and non-ferrous metals. The W153 cylinder shape (Point Shape Code W153) is a standard profile used when flat-faced contact and side grinding are both required. At 120 grit fine grade, it is appropriate for finishing passes and light material removal where surface quality matters. Machinists, toolmakers, and metal fabricators are the primary users, though maintenance technicians also use mounted points for cleanup and repair work in the field.

Key Features

• Cylinder W153 point shape for flat-face and side grinding contact
• 120 grit fine grade aluminum oxide abrasive for controlled stock removal and smooth finish
• Vitrified bond with hard density rating for durability and consistent cutting action
• Rated to 80,850 RPM for compatibility with standard die grinders
• 1-1/2 inch shank length provides reach into bores and recessed workpiece areas
• Blue color coding for easy grit and grade identification at the bench

Compatibility

Designed as an OEM-style replacement or standard-supply mounted point for die grinders and rotary tools accepting a standard straight shank. Verify that the spindle speed of the tool does not exceed the 80,850 RPM rating of this point before use.

Installation Notes

Mounted points are installed and removed by a licensed machinist or trained fabricator using the appropriate collet or chuck on a die grinder or rotary tool. Always confirm the tool spindle speed does not exceed the maximum RPM stamped or listed for the abrasive before mounting. Inspect the point for cracks or chips before each use and discard any damaged point immediately. Follow ANSI B7.1 and applicable shop safety standards when using bonded abrasives, including proper eye protection and guarding.
