Tru-maxx 66253291807 Cone Mounted Point 60 Grit A1 Aluminum Oxide

Product Description

The TRU-MAXX 66253291807 is an A1-shape cone mounted point designed for precision grinding, deburring, and surface finishing on metal and ferrous materials. Built with aluminum oxide abrasive bonded in a vitrified bond matrix, it delivers consistent stock removal and controlled wear across the contact surface. The cone profile measures 2.5 inches thick and mounts on a 0.25-inch diameter shank with a 1.5-inch shank length, making it compatible with standard die grinders and rotary tools. Rated at a maximum of 20,960 RPM, this 60-grit medium-grade point suits applications where aggressive material removal is needed before a finishing pass. Weighing 0.02 pounds, it adds minimal mass to the spindle during extended use.

This mounted point is suited for tool-and-die work, weld cleanup, port grinding, mold finishing, and general metalworking operations in both shop and field environments. The A1 cone shape reaches into contoured surfaces, inside radii, and recessed areas that flat or cylindrical wheels cannot access. Machinists, maintenance technicians, and fabricators typically use this style of point with pneumatic or electric die grinders to remove burrs, blend welds, or prepare surfaces ahead of inspection or coating. It is sold individually, making it practical for targeted replacement or trial use before committing to larger quantities.

Key Features

• A1 cone shape reaches contoured surfaces, inside radii, and recessed cavities
• Aluminum oxide abrasive with vitrified bond for consistent cut rate and shape retention
• 60 grit medium grade balances stock removal speed with surface finish quality
• 0.25-inch shank diameter fits standard die grinder collets and rotary tool chucks
• 20,960 RPM maximum speed rating supports high-speed pneumatic and electric die grinders
• Lightweight at 0.02 pounds, reducing spindle fatigue during extended grinding sessions

Compatibility

Designed as an OEM-style mounted point for use with die grinders and rotary tools accepting a 0.25-inch shank collet.

Installation Notes

Mounted points must be installed by trained personnel familiar with abrasive tooling safety. Before mounting, confirm the tool spindle RPM rating meets or exceeds the 20,960 RPM maximum stamped on the point — never use a point on a machine that exceeds its rated speed. Secure the shank fully into the collet according to the tool manufacturer's minimum insertion depth specification and tighten the collet nut firmly before operation. Always dress or inspect the point for cracks or chips before each use, and wear appropriate eye protection and a face shield during grinding.
