Grier Abrasives B44-N2-17299 Mounted Point Fine Aluminum Oxide

Product Description

The GRIER ABRASIVES B44-N2-17299 is a tree-shaped mounted point designed for precision grinding and finishing work on metal and hard materials. Built with aluminum oxide abrasive and a unitized bond, this mounted point delivers consistent material removal at a fine grade. It runs on a 1/8 inch shank and is rated to a maximum of 68400 RPM, making it suitable for high-speed die grinders and rotary tools. Licensed tradespeople and experienced machinists use mounted points like this for deburring, blending, and port work in tight or contoured areas that flat wheels cannot reach.

This mounted point is well-suited for grinding and finishing operations in fabrication shops, tool rooms, and maintenance environments. The B44 tree profile allows access to concave surfaces, grooves, and recessed bores. At a fine grade with medium density, it is appropriate for finishing passes and light material removal rather than aggressive stock removal. It is typically used on ferrous metals, cast iron, and hardened steel.

Key Features

• B44 tree point shape for access to contoured and recessed surfaces
• Aluminum oxide abrasive for use on ferrous metals and hardened steel
• Fine grade with medium density for finishing and light material removal
• Unitized bond construction for consistent performance throughout the wheel life
• 1/8 inch shank diameter fits standard die grinder collets
• Maximum rated speed of 68400 RPM for high-speed rotary tool compatibility

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch shank collet. Suitable as an OEM-style replacement or direct-fit abrasive point in standard grinding setups requiring a B44 tree profile.

Installation Notes

Installation and use should be performed by qualified machinists, tool-and-die technicians, or grinding professionals familiar with abrasive wheel safety. Always confirm the tool spindle speed does not exceed the 68400 RPM rating of this mounted point before operating. Inspect the point for cracks or damage before mounting, and ensure the shank is fully seated in the collet before tightening. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
