Tru-maxx 66253292078 Mounted Point W145 60 Grit

Product Description

The TRU-MAXX 66253292078 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in tight spaces and contoured areas. Shaped as a cylinder (shape code W145), this mounted point runs at up to 105,000 RPM on a rotary tool, die grinder, or flex-shaft machine. It measures 3/8 inches in head thickness and mounts on a 1/8-inch diameter shank that is 1-1/2 inches long. The 60-grit medium grade aluminum oxide abrasive removes material efficiently while leaving a consistent finish. Machinists, tool-and-die workers, and maintenance technicians use these points for internal bore work, weld cleanup, and cavity finishing on ferrous and non-ferrous metals.

This mounted point is suited for use in die grinding applications across production, maintenance, and repair environments. The cylinder profile makes it effective for flat bottom cavities, internal grooves, and shoulder blending. It fits standard 1/8-inch collets found on most pneumatic and electric die grinders. The medium grit is a common first-choice grade for stock removal before finishing passes with finer abrasives. Typical users include machinists, mold makers, fabricators, and industrial maintenance mechanics working on ferrous metals, castings, and welds.

Key Features

• Cylinder shape (W145) suited for flat-bottom cavities and internal bore grinding
• 60-grit medium grade aluminum oxide for efficient stock removal on metal
• 1/8-inch shank diameter fits standard die grinder and rotary tool collets
• Maximum rated speed of 105,000 RPM for high-speed rotary tools
• Pink aluminum oxide abrasive provides consistent cut rate on ferrous materials
• 1-1/2-inch shank length allows reach into recessed work areas

Compatibility

Designed for use with die grinders, rotary tools, and flex-shaft machines equipped with a standard 1/8-inch collet. Verify that the tool RPM rating meets or exceeds the 105,000 RPM maximum speed of this mounted point before use.

Installation Notes

Installation is performed by trade machinists, maintenance mechanics, or fabricators using standard die grinder collet hardware. Always confirm the tool spindle speed does not exceed the 105,000 RPM rating marked on the point. Inspect the mounted point for cracks or chips before each use and discard if any damage is found. Wear appropriate eye protection and follow ANSI B7.1 safety requirements for grinding wheel use.
