Tru-maxx 66253292134 Mounted Point W189 60 Grit Medium

Product Description

The TRU-MAXX 66253292134 is a W189 cylinder-profile mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. It uses an aluminum oxide abrasive at 60 grit with a medium grade, making it well-suited for stock removal work where a balance of cut rate and surface finish is required. The point measures 2 inches thick with a 1/4-inch shank diameter and a 1-1/2-inch shank length, and it is rated for a maximum of 26,830 RPM. The pink aluminum oxide bond is a standard choice for grinding ferrous metals without loading. Machinists, tool-and-die technicians, and maintenance professionals install these points in die grinders and rotary tools for internal bore work, port finishing, and weld cleanup.

This mounted point is used in metalworking, fabrication, maintenance, and repair applications. It fits standard 1/4-inch collet die grinders and rotary tools common in machine shops, production lines, and field maintenance environments. The W189 cylinder shape provides flat-end contact, making it effective for bottom grinding in blind holes, slot finishing, and flat-surface deburring. It is sold individually and is a consumable replacement point for ongoing grinding operations.

Installation Notes

Mounted points must be installed by securely seating the shank into a properly sized collet before tightening. Always verify the tool spindle speed does not exceed the 26,830 RPM maximum rating marked for this point before operation. Inspect the point for cracks or damage before each use and discard any point that shows visible defects. Use appropriate eye protection and guards per applicable safety standards when operating grinding equipment.
