Tru-maxx 66253292099 Mounted Point 60 Grit W229 Aluminum Oxide

Product Description

The TRU-MAXX 66253292099 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal workpieces. Formed in a W229 cylinder shape, this abrasive point delivers consistent stock removal in bores, cavities, and contoured surfaces where flat wheels cannot reach. It runs at a maximum rated speed of 30,370 RPM and carries a 60-grit, medium-grade abrasive matrix suited for moderate material removal without excessive heat buildup. The pink aluminum oxide grain is well-suited to ferrous metals and general-purpose bench or die grinder applications. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this type of tooling.

This mounted point is intended for use with rotary die grinders, electric or pneumatic, equipped with a 1/4-inch collet. It is appropriate for production grinding and maintenance work on steel, iron, and similar hard metals in both shop and field settings. The cylinder profile makes it effective for internal grinding of cylindrical bores, cleaning weld seams, and blending surfaces in tight access areas.

Key Features

• W229 cylinder point shape for internal bore and cavity grinding
• 60-grit medium grade for balanced material removal and surface finish
• Aluminum oxide abrasive construction suited for ferrous metals
• 1/4-inch shank diameter fits standard die grinder collets
• 30,370 RPM maximum rated speed for die grinder compatibility
• Pink color designation consistent with aluminum oxide abrasive identification

Compatibility

Designed for use with die grinders and rotary tools fitted with a 1/4-inch collet chuck. Consult grinder RPM rating before mounting to confirm the tool does not exceed the 30,370 RPM maximum.

Installation Notes

Installation and use should be performed by machinists or maintenance technicians familiar with abrasive tooling safety practices. Always power down and disconnect the grinder before inserting or removing the mounted point. Verify the grinder spindle speed does not exceed the rated maximum RPM of the abrasive point before operating. Wear appropriate eye protection and follow applicable ANSI abrasive safety standards during use.
