Tru-maxx 66253291644 Mounted Point 60 Grit A25 1/4 in Shank

Product Description

The TRU-MAXX 66253291644 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. Shaped to the A25 ball profile, this mounted point fits a 0.25 inch shank and spins at up to 35,510 RPM under a vitrified bond that holds the 60 grit abrasive firmly during aggressive stock removal. At 0.02 pounds, it is lightweight enough for extended use in die grinders and rotary tools. It is sold individually and is well suited for HVAC, plumbing, and general fabrication shops where internal bore work or weld cleanup is part of the job.

This mounted point is used in die grinders, bench grinders with flexible-shaft attachments, and rotary tools wherever access to tight interior surfaces is needed. Typical applications include cleaning burrs from pipe ends, grinding weld seams inside fittings, and shaping or blending metal in confined cavities. The medium grade and 60 grit make it effective for moderate stock removal without excessive surface roughness. It suits both production and maintenance environments where consistent, repeatable grinding performance is required.

Key Features

• A25 ball-shape profile for grinding in curved and confined surfaces
• 60 grit medium grade aluminum oxide abrasive for balanced stock removal and finish
• Vitrified bond provides rigid abrasive retention and consistent cut throughout wheel life
• 0.25 inch shank diameter fits standard die grinder and rotary tool collets
• Rated to 35,510 RPM for use in high-speed rotary applications
• Lightweight at 0.02 pounds for reduced fatigue during extended grinding tasks

Compatibility

Designed as a standard replacement or stock-up item for die grinders and rotary tools accepting a 0.25 inch shank mounted point.

Installation Notes

Mounted points must be installed and operated by personnel familiar with abrasive tool safety. Always verify the tool spindle speed does not exceed the 35,510 RPM rating marked on the point before mounting. Secure the shank fully in the collet and tighten to the tool manufacturer specification before operation. Wear appropriate eye protection and follow ANSI B11 and OSHA abrasive safety guidelines during use.
