Tru-maxx TM-140BE8RD1 W140 Mounted Point 120 Grit

Product Description

The TRU-MAXX TM-140BE8RD1 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on metal and hard materials. It features a W140 cylinder profile with a 120-grit aluminum oxide abrasive grain bonded in a vitrified bond at hard density. The 0.25-inch head thickness and 1.75-inch overall length make it well suited for internal grinding, port work, and detail finishing in confined areas. It is rated to a maximum of 105,000 RPM, making it compatible with high-speed die grinders and pneumatic rotary tools commonly used by machinists, tool and die workers, and metal fabricators.

This mounted point is used in applications requiring controlled material removal and fine surface finishing. The fine 120-grit aluminum oxide construction is appropriate for ferrous metals, cast iron, hardened steel, and similar materials. It fits a standard 0.25-inch shank chuck and is commonly used in die grinding, weld blending, chamfering, and internal bore finishing operations in both shop and field service environments. The blue vitrified bond provides consistent grain exposure throughout the life of the wheel.

Key Features

• 1.5-inch shank length fits standard 0.25-inch collet chucks
• Overall length of 1.75 inches for reach into bores and recesses

Compatibility

Designed as a standard 0.25-inch shank mounted point compatible with pneumatic and electric die grinders and rotary tools accepting a 0.25-inch collet or chuck.

Installation Notes

Installation and use should be performed by qualified machinists or trades personnel familiar with abrasive wheel safety. Always verify that the tool spindle speed does not exceed the 105,000 RPM maximum rating marked on the mounted point before mounting. Inspect the abrasive head for cracks or chips before each use and discard any damaged point. Secure the shank firmly in the collet and tighten to the tool manufacturer's specification before operating.
