Tru-maxx 66253291589 Mounted Point B43 60 Grit

Product Description

The TRU-MAXX 66253291589 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on ferrous metals and hardened materials. Shaped to a B43 pointed profile, this mounted point measures 5/16 inches thick with a 1/8 inch shank diameter and a 1-1/2 inch shank length. It runs at a maximum of 76,160 RPM, making it suitable for die grinders and rotary tools used in toolroom, maintenance, and fabrication applications. Grit is rated at 60 with a medium grade, offering an efficient balance between material removal and surface finish control. Machinists, toolmakers, and maintenance technicians are the typical users.

This mounted point is used for internal grinding, slot grinding, and contour finishing in areas that are difficult to reach with conventional abrasive wheels. The pointed B43 shape allows access into tight bores, cavities, and angled surfaces. Common applications include cleaning weld flash, blending casting marks, and refining machined surfaces in both shop and field repair settings. It is suited for use in manufacturing, metalworking, and industrial maintenance environments where a die grinder or high-speed rotary tool is standard equipment.

Installation Notes

Mounted points must be installed by a qualified operator familiar with abrasive tooling safety requirements. Verify that the tool's rated RPM meets or exceeds the maximum RPM of 76,160 before use. Inspect the shank for damage before mounting, and ensure the collet is properly tightened before operation. Always use appropriate eye protection and follow ANSI B11 or applicable shop safety standards when operating high-speed abrasive tools.
