Tru-maxx TM-146AK8TD1 Mounted Point W146 120 Grit Fine

Product Description

The TRU-MAXX TM-146AK8TD1 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and other hard materials. Shaped as a cylinder (W146 profile), this mounted point measures 0.5 inches thick with a 0.125-inch shank diameter and a 1.5-inch shank length, giving an overall length of 2 inches. At 120 grit and a Fine grade with Hard density, it removes material efficiently while leaving a controlled surface finish. Rated to 105,000 RPM, it fits standard die grinders and rotary tools used by machinists, tool-and-die workers, and maintenance technicians.

This mounted point is suited for internal bore grinding, slot finishing, weld cleanup, and accessing tight or contoured areas where larger abrasives cannot reach. The 0.125-inch shank fits collets commonly found on die grinders, flexible shaft machines, and rotary tools used in production and maintenance environments. It is appropriate for use on ferrous metals, cast iron, and hardened steel surfaces in both shop and field applications.

Key Features

• W146 cylinder profile for flat-face and side-contact grinding in confined areas
• 120 grit, Fine grade aluminum oxide abrasive for controlled stock removal and finish work
• Hard density vitrified bond maintains wheel form and extends service life on hard workpieces
• Rated to 105,000 RPM for compatibility with high-speed die grinders and rotary tools
• 0.125-inch shank diameter fits standard collets on common rotary and die grinder tooling
• Overall length of 2 inches provides reach into bores, slots, and recessed features

Compatibility

Designed as a standard W146 cylinder mounted point for use with die grinders, flexible shaft machines, and rotary tools accepting a 0.125-inch shank collet. Verify that the tool's rated RPM meets or exceeds the workpiece and application requirements before use.

Installation Notes

Mounted points must be installed by personnel familiar with abrasive tooling safety practices per ANSI B7.1 guidelines. Inspect the point for chips or cracks before mounting and ensure the host tool is rated for at least 105,000 RPM before operation. Power down and disconnect the tool from its power source before inserting or removing the shank from the collet. Do not exceed the maximum RPM marked on the abrasive and always use appropriate eye and face protection during grinding operations.
