Tru-maxx 66253291676 Mounted Point W158 60 Grit 1/8 in

Product Description

The TRU-MAXX 66253291676 is an aluminum oxide mounted point in W158 cylinder shape, designed for precision grinding, deburring, and surface finishing on metal and other hard materials. It carries a 60-grit, medium-grade abrasive that removes material efficiently while leaving a controlled surface finish. The 1/8-inch shank diameter fits standard die grinder collets and rotary tool chucks. With a maximum operating speed of 70,500 RPM, this mounted point is suited for high-speed tooling setups common in fabrication, maintenance, and toolroom environments. Machinists, tool-and-die technicians, and metalworking professionals use this type of abrasive to reach confined areas that larger grinding wheels cannot access.

This mounted point is well suited for internal grinding, port work, weld cleanup, and deburring operations on ferrous and non-ferrous metals. The cylinder profile of the W158 shape makes it effective for flat-bottom bores, slots, and recessed surfaces. It is commonly used in job shop, production, and maintenance-repair-operations (MRO) settings where a consistent, repeatable abrasive tool is needed for detail work. The 1/8-inch shank and compact head geometry allow it to fit into tight clearances on castings, molds, and machined components.

Key Features

• W158 cylinder point shape for flat-bottom and recessed surface grinding
• 60-grit aluminum oxide abrasive rated for medium material removal on metal
• 1/8-inch shank diameter compatible with standard die grinder and rotary tool collets
• Maximum operating speed of 70,500 RPM for high-speed grinding applications
• 1/8-inch head thickness and 1-1/2-inch shank length for reach into confined areas
• Blue color coding for quick grit and grade identification at the workbench

Compatibility

Designed for use in die grinders, rotary tools, and drill press setups equipped with a 1/8-inch collet or chuck. Suitable for use on ferrous metals, castings, and similar hard materials in grinding and deburring applications.

Installation Notes

Installation and operation of mounted points should be performed by machinists or technicians familiar with abrasive tooling safety. Always inspect the mounted point for cracks or damage before mounting, and never exceed the rated maximum RPM of 70,500. Ensure the grinder or rotary tool is powered off and unplugged before inserting or removing the shank from the collet. Always wear appropriate eye protection and follow applicable ANSI B11 abrasive safety standards during use.
