Grier Abrasives B44-N3-17561 Mounted Point Medium Grade

Product Description

The GRIER ABRASIVES B44-N3-17561 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. It features a B44 tree-shaped abrasive head that is 3/8 inches thick, mounted on a 1/8-inch diameter shank that is 1.5 inches long. The medium-grade, unitized bond construction delivers consistent material removal with controlled cut rates. Rated to a maximum of 68,400 RPM, this mounted point handles high-speed die grinder applications. The green color designation identifies the aluminum oxide medium density abrasive composition. Machinists, tool-and-die technicians, and fabricators use this point for internal radius work, contour grinding, and weld blending.

This mounted point suits die grinder and rotary tool applications in metal fabrication, maintenance repair, and toolroom environments. The tree profile is well matched to contoured surfaces, internal cavities, and angled relief grinding where flat or cylindrical wheels cannot reach. It is appropriate for ferrous and non-ferrous metal grinding tasks in both production and maintenance settings. The 1/8-inch shank is compatible with standard die grinder collets.

Key Features

• B44 tree-shaped point profile for contour and internal grinding applications
• Aluminum oxide abrasive with medium grade for balanced cut rate and finish
• Unitized bond type provides consistent abrasive exposure through the wheel life
• Maximum rated speed of 68,400 RPM for use with high-speed die grinders
• 1/8-inch shank diameter fits standard die grinder collets
• Green color coding identifies medium-density aluminum oxide composition

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8-inch collet. Suitable for general-purpose mounted point grinding applications on metal surfaces.

Installation Notes

Installation of mounted points is performed by machinists, fabricators, and maintenance technicians using a die grinder or rotary tool. Always confirm the tool spindle speed does not exceed the 68,400 RPM maximum rated speed before operation. Inspect the shank for cracks or damage before mounting, and ensure the collet is properly tightened. Wear appropriate personal protective equipment including eye protection whenever operating abrasive tooling.
