Grier Abrasives B44-N3-18151 Mounted Point Tree Shape

Product Description

The GRIER ABRASIVES B44-N3-18151 is a B44 tree-shaped mounted point designed for precision grinding, deburring, and surface blending on metal and hard materials. Built with aluminum oxide abrasive and a unitized bond, this mounted point delivers consistent medium-grade stock removal in tight spaces and contoured surfaces. The 3/8 inch head thickness and green color coding identify the medium density and hardness grade. Rated to 57,000 RPM, it is suitable for use with die grinders and rotary tools in production and maintenance grinding applications. It is installed by machinists, tool-and-die technicians, and maintenance professionals across metalworking and fabrication environments.

This mounted point fits standard rotary die grinders and high-speed spindle tools that accept a 3/32 inch shank. The tree point shape makes it well suited for grinding inside cavities, weld seating areas, ports, and irregular profiles where flat or cylindrical wheels cannot reach. It is commonly used in metal fabrication shops, tooling rooms, and general maintenance operations requiring controlled material removal on ferrous and non-ferrous metals.

Key Features

• B44 tree point shape for access to contoured surfaces and recessed areas
• Aluminum oxide abrasive with unitized bond for consistent, controlled cutting action
• Medium grade and medium density for balanced stock removal and surface finish
• Rated to 57,000 RPM for compatibility with high-speed die grinders
• 3/32 inch shank diameter fits standard rotary tool and die grinder collets
• Green color coding identifies medium grade for easy shop-floor identification

Compatibility

Designed to fit rotary die grinders and spindle tools accepting a 3/32 inch shank diameter. Verify that the tool spindle speed does not exceed the 57,000 RPM maximum rating of this mounted point before use.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder collet wrench. Always confirm the tool is unplugged or the air supply is disconnected before mounting or removing the point. Do not exceed the 57,000 RPM maximum spindle speed marked on the point. Inspect the abrasive head for chips or cracks before each use and discard any damaged point immediately.
