Tru-maxx 66253291850 Mounted Point B43 60 Grit

Product Description

The TRU-MAXX 66253291850 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface blending on metal and ferrous workpieces. This B43 pointed-shape abrasive mounts to a rotary tool, die grinder, or flexible shaft machine via a 1/8 inch shank and spins up to 76,160 RPM. At 60 grit with a medium grade, it removes material at a moderate rate while leaving a reasonably smooth finish. The pink aluminum oxide composition is suited for grinding steel, tool steel, and similar hard metals. It weighs 0.02 pounds and is sold individually.

This mounted point is used in machine shops, fabrication facilities, and maintenance environments where access to tight spaces, ports, bores, or weld joints is required. The pointed B43 profile allows contact in confined or contoured areas that flat or cylindrical wheels cannot reach. It is a common choice for toolroom work, mold and die finishing, and general metalworking operations. The 1/8 inch shank diameter fits standard collets on die grinders and rotary tools widely used in industrial and trade applications.

Key Features

Compatibility

Designed for use with die grinders, rotary tools, and flexible shaft machines equipped with a 1/8 inch collet. Suitable for grinding steel, tool steel, and other ferrous metals in toolroom, fabrication, and maintenance applications.

Installation Notes

Mounted points must be installed in a collet that matches the shank diameter exactly — a 1/8 inch shank requires a 1/8 inch collet. Before mounting, verify the tool spindle speed does not exceed the 76,160 RPM rating marked for this abrasive. Always inspect the mounted point for cracks or chips before use and discard any damaged piece. Eye protection and appropriate guarding per ANSI B7.1 standards are required when operating any bonded abrasive.
