Tru-maxx 66253291822 Mounted Point W161 60 Grit 1/8 Inch Shank

Product Description

The TRU-MAXX 66253291822 is a W161 cylinder-shape mounted point designed for precision grinding, deburring, and surface finishing in tight or contoured workspaces. It uses a 60-grit aluminum oxide abrasive with a medium grade, delivering consistent stock removal on ferrous metals and general-purpose workpiece materials. The shank diameter is 1/8 inches, the shank length is 1.5 inches, and the head thickness is 5/16 inches. Rated to a maximum of 77,250 RPM, this mounted point is suited for use with die grinders and rotary tools operated by machinists, tool-and-die workers, and maintenance technicians in shop or field environments.

This mounted point fits applications where a small-diameter abrasive tool is needed to reach bores, cavities, weld joints, or complex profiles that larger grinding wheels cannot access. Typical use cases include weld blending, port work, mold finishing, and deburring of castings or machined components. The aluminum oxide abrasive performs reliably on steel, cast iron, and similar hard metals. Its compact geometry and standard 1/8-inch shank make it compatible with a wide range of rotary and die grinder collets commonly found in production and maintenance shops.

Key Features

• W161 cylinder point shape for consistent contact on flat, contoured, and recessed surfaces
• 60-grit aluminum oxide abrasive rated for general-purpose stock removal on ferrous metals
• Medium grade provides a balance between aggressive cutting and controlled surface finish
• Maximum rated speed of 77,250 RPM for compatibility with standard high-speed die grinders
• 1/8-inch shank diameter fits the most common die grinder and rotary tool collet sizes
• Lightweight at 0.02 pounds, minimizing operator fatigue during extended use

Compatibility

Designed as a standard 1/8-inch shank mounted point for use with die grinders, pencil grinders, and rotary tools that accept 1/8-inch collets. Confirm the tool spindle speed does not exceed 77,250 RPM before use.

Installation Notes

Mounted points must be installed in a properly sized collet and tightened securely before operation. Always verify the tool RPM rating meets or does not exceed the 77,250 RPM maximum marked on this abrasive. Wear appropriate eye protection and follow ANSI B11 and applicable shop safety standards when operating rotary abrasive tools. Inspect the mounted point for cracks or damage before each use and discard if any defect is found.
