Grier Abrasives B52-N2-17665 Mounted Point Fine Aluminum Oxide

Product Description

The GRIER ABRASIVES B52-N2-17665 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and similar hard materials. This unitized abrasive point features a B52 pointed shape with a fine grade, making it well suited for detailed work in tight cavities, contoured surfaces, and hard-to-reach areas. The medium-density bond holds abrasive grains firmly during high-speed operation, with a maximum rated speed of 23000 RPM. Machinists, tool-and-die workers, and fabrication professionals use this type of mounted point with electric or pneumatic die grinders for controlled material removal.

This mounted point is appropriate for bench grinder work, die grinder applications, and spindle-mounted finishing tasks in both production and maintenance environments. The fine grade makes it a good choice for finish passes and light deburring rather than aggressive stock removal. The green color identifies the aluminum oxide abrasive formulation used in this specific series. It is sold and packaged individually as a single unit.

Key Features

• B52 pointed shape provides access to narrow grooves, cavities, and contoured profiles
• Aluminum oxide abrasive material with unitized bond construction for consistent grain exposure
• Fine grade suited for finish grinding and light deburring work
• Medium density and hardness for controlled cut rate and extended wheel life
• Maximum operating speed of 23000 RPM compatible with standard die grinder tooling
• 3/32 inch shank diameter fits common collet sizes on electric and pneumatic die grinders

Compatibility

Designed for use with die grinders and spindle-mounted grinding equipment that accept a 3/32 inch shank diameter. Verify that the tool spindle speed does not exceed the rated maximum of 23000 RPM before mounting.

Installation Notes

Mounting of abrasive points should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Confirm the die grinder is disconnected from power or air supply before installing or removing the mounted point. Inspect the point for cracks or damage before each use and discard any point showing visible defects. Always wear appropriate eye protection and ensure the work area is clear before bringing the grinder up to operating speed.
