Tru-maxx 66253291581 Mounted Point 60 Grit B105 1/8 in Shank

Product Description

The TRU-MAXX 66253291581 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. Shaped as an inverted cone with a flat end (shape code B105), this mounted point carries a 60-grit medium-grade abrasive that removes material efficiently while leaving a consistent surface finish. The 1/8-inch shank diameter mounts directly into standard die grinders and rotary tools. With a maximum operating speed of 76,160 RPM and a shank length of 1.5 inches, it suits both bench-mounted and handheld power tool applications. Machinists, tool-and-die workers, and maintenance technicians reach for this style of mounted point for internal bore work, weld cleanup, and cavity grinding.

This mounted point is suited for shop and field use wherever a die grinder or rotary tool is the right instrument. Common applications include deburring cast iron and steel, blending weld seams, cleaning up machined cavities, and general stock removal on hard surfaces. The inverted cone flat-end geometry allows access to angled surfaces and recessed areas that flat or cylindrical wheels cannot reach. It is typically used in metalworking, maintenance and repair operations, and tool-and-die environments.

Key Features

• Inverted cone flat-end shape (B105) for access to recessed and angled surfaces
• Aluminum oxide abrasive construction suited for grinding ferrous metals and hard materials
• 60-grit medium grade balances material removal rate with surface finish quality
• 1/8-inch shank diameter fits standard die grinder and rotary tool collets
• Rated to 76,160 RPM maximum operating speed
• Compact head at 0.25 inches thick for controlled, precise grinding contact

Compatibility

Designed as a standard replacement or stock mounted point for die grinders and rotary tools that accept a 1/8-inch shank collet.

Installation Notes

Mounted points must be installed and used by personnel familiar with abrasive wheel safety. Always confirm the tool spindle speed does not exceed the 76,160 RPM maximum rating marked for this point before mounting. Inspect the abrasive head for cracks or chips before each use and discard any damaged point immediately. Secure the shank fully into the collet per the tool manufacturer specifications and ensure the collet nut is properly tightened before operating.
