Tru-maxx 66253292051 W142 Mounted Point 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253292051 is a W142 cylinder-shape aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and ferrous materials. The abrasive head measures 0.25 inches thick and mounts on a 0.125-inch diameter shank that is 1.5 inches long. At 60 grit with a medium grade, this mounted point removes material efficiently while leaving a controlled surface finish. It is rated to a maximum of 105,000 RPM, making it suitable for use with high-speed die grinders and rotary tools. Machinists, tool-and-die technicians, and fabricators are the primary users of this type of abrasive.

This mounted point is suited for internal grinding, cavity work, and hard-to-reach areas in both production and maintenance environments. The W142 cylinder shape is a common profile for grinding cylindrical bores, ports, and recessed surfaces on steel, cast iron, and similar alloys. It is sold individually per package with a minimum order quantity of five units, making it practical for shop restocking. Pink aluminum oxide is well matched to hardened steels and tool steels where consistent cut rate and wheel life are important.

Key Features

• Lightweight at 0.02 pounds per unit

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.125-inch shank collet. Verify the tool spindle speed does not exceed the 105,000 RPM maximum rating before use.

Installation Notes

Installation is performed by machinists or fabricators using a standard die grinder with a matching collet size. Secure the shank fully into the collet before operation and confirm the tool is rated at or below 105,000 RPM. Always wear appropriate eye protection and ensure the workpiece is properly secured. Inspect the mounted point for cracks or chips before each use and discard any damaged abrasive immediately.
