Tru-maxx 66253291607 B42 Mounted Point 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253291607 is an aluminum oxide mounted point designed for grinding, deburring, and surface finishing on metal and hard materials. Shaped to the B42 pointed profile, this abrasive is well suited to reaching into tight contours, bores, and cavities where flat or wheel-style abrasives cannot reach. The 60-grit medium grade removes material efficiently while leaving a consistent surface finish. The 0.125-inch shank mounts directly into a die grinder or rotary tool and is rated to a maximum of 61,320 RPM for use at typical operating speeds. Machinists, tool-and-die workers, and metal fabricators are the primary installers of this type of abrasive accessory.

This mounted point is suited for precision deburring, weld cleanup, mold finishing, and general stock removal on ferrous and non-ferrous metals. The B42 point shape is a standard geometry used across die grinding applications where a tapered or pointed contact area is needed. The medium grit makes it a practical choice for intermediate material removal between coarse shaping and fine finishing stages. It is packaged and sold as a single unit.

Key Features

• B42 pointed shape for access to contours, slots, and hard-to-reach surfaces
• 60 grit medium grade balances material removal rate with surface finish quality
• Aluminum oxide abrasive material provides durability on steel and hard metals
• 0.125-inch shank diameter fits standard die grinders and rotary tool collets
• 1.5-inch shank length provides clearance for deeper reach applications
• Rated to 61,320 RPM for compatibility with high-speed rotary tools

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.125-inch shank collet. Verify maximum RPM rating of the host tool does not exceed 61,320 RPM before use.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a die grinder or compatible rotary tool with a matching collet size. Ensure the tool is powered off and unplugged before inserting or removing the shank. Do not exceed the marked maximum RPM of 61,320. Always use appropriate eye protection and follow applicable shop safety standards when operating rotary abrasive tools.
