Tru-maxx 66253291543 A37 60 Grit Mounted Point 1/4 in

Product Description

The TRU-MAXX 66253291543 is an aluminum oxide mounted point in the A37 wheel-with-tapered-edge shape, designed for precision grinding and deburring on metal workpieces. Running at up to 30,560 RPM, this medium-grade, 60-grit abrasive delivers consistent stock removal and surface conditioning in tight spaces and contoured areas. The vitrified bond provides rigidity and good form retention during use. The 0.02-pound unit ships individually and is well suited to die grinders and rotary tools used in fabrication, maintenance, and tool-and-die work.

This mounted point is used in shop and field applications where a standard bench grinder cannot reach — including internal diameter grinding, weld cleanup, port matching, and cavity finishing on ferrous metals and alloys. It fits any die grinder or rotary tool accepting a 1/4-inch shank. The pink aluminum oxide grain is a common choice for hardened steels and tool steels where a friable, cool-cutting abrasive is preferred.

Key Features

• A37 wheel-with-tapered-edge profile for contoured surface and internal grinding access
• 60 grit, medium grade aluminum oxide for moderate stock removal and surface blending
• Vitrified bond construction maintains wheel shape and rigidity under load
• Maximum rated speed of 30,560 RPM compatible with standard die grinders
• 1/4-inch shank diameter and 1-1/2-inch shank length for broad tool compatibility
• Lightweight at 0.02 pounds — minimal added weight to the tool during overhead or detailed work

Compatibility

Designed to fit die grinders and rotary tools with a 1/4-inch collet or chuck. Confirm the tool spindle speed does not exceed the 30,560 RPM maximum rating before use.

Installation Notes

Installation and use of mounted abrasive points should follow ANSI B7.1 safety standards for grinding wheel use. Always confirm the tool's rated RPM does not exceed the wheel's 30,560 RPM maximum before mounting. Inspect the point for cracks or chips prior to each use and discard any damaged units. Wear appropriate eye and face protection whenever operating rotary abrasives.
