Grier Abrasives B44-N2-18150 Mounted Point Tree Shape

Product Description

The GRIER ABRASIVES B44-N2-18150 is an aluminum oxide mounted point in a B44 tree shape, designed for precision grinding, deburring, and surface finishing on metal and hard materials. It features a fine grade abrasive with a unitized bond and medium density construction, rated to a maximum of 57,000 RPM. The 3/32-inch shank mounts directly into a die grinder or rotary tool, making it a practical choice for machinists, fabricators, and tool-and-die professionals who need controlled material removal in tight or contoured areas.

This mounted point suits applications in metalworking shops, maintenance environments, and precision fabrication settings. The tree-shaped profile makes it well suited for grinding internal radii, ports, cavities, and irregular contours where flat or cylindrical wheels cannot reach. The fine grade is appropriate for finishing passes and light stock removal rather than aggressive material takedown. It is commonly used on ferrous metals, castings, and weld cleanup work.

Key Features

• B44 tree shape profile for grinding internal contours, cavities, and irregular surfaces
• Fine grade aluminum oxide abrasive for controlled finishing and light stock removal
• Unitized bond with medium density for consistent cut and wear characteristics
• Maximum rated speed of 57,000 RPM for use with standard die grinders
• 3/32-inch shank diameter compatible with common rotary tool collets
• Green color coding for quick grade and material identification at the bench

Compatibility

Designed as an OEM-style replacement or standard consumable mounted point for die grinders and rotary tools accepting a 3/32-inch shank collet.

Installation Notes

Mounted points of this type are installed and replaced by machinists, fabricators, or maintenance technicians using standard die grinder or rotary tool collet procedures. Before mounting, confirm the tool's rated RPM meets or exceeds the 57,000 RPM maximum stamped on this point - never exceed the marked speed rating. Inspect the point for cracks or damage before each use and discard any damaged abrasive immediately. Secure the shank fully in the collet and tighten per the tool manufacturer's guidance before operating.
