Grier Abrasives B44-N4-17566 Mounted Point Tree Shape

Product Description

The GRIER ABRASIVES B44-N4-17566 is a B44 tree-shaped mounted point designed for precision grinding, deburring, and surface finishing on hard materials. Constructed from aluminum oxide abrasive with a unitized bond and a very hard density rating, this mounted point delivers aggressive stock removal at coarse grade. It is rated to 68400 RPM and fits standard rotary tools, die grinders, and CNC spindles via its 1/8-inch shank. The green-colored wheel body provides quick visual identification on the tool floor. At 0.006 pounds, it is lightweight enough for extended handheld use without operator fatigue.

This mounted point is suited for grinding and finishing operations on ferrous metals, castings, welds, and hardened steel components. It is commonly used by machinists, tool-and-die makers, maintenance technicians, and fabricators working in industrial and production environments. The tree profile allows access to contoured surfaces, slots, cavities, and hard-to-reach internal profiles where flat or cylindrical wheels cannot reach effectively.

Installation Notes

Mounted points must be installed and operated by qualified personnel following applicable ANSI B7.1 safety standards for abrasive wheels. Always verify the tool spindle speed does not exceed the 68400 RPM rating marked on the product before mounting. Inspect the point for cracks or damage before each use and never use a damaged abrasive. Wear appropriate eye protection and ensure all guards are in place prior to operation.
