Grier Abrasives A25-N3-17833 Mounted Point Ball Shape

Product Description

The GRIER ABRASIVES A25-N3-17833 is an aluminum oxide mounted point in an A25 ball shape, designed for precision grinding, deburring, and surface finishing on metal and other hard materials. This mounted point features a medium grade abrasive bond with a unitized construction, making it well suited for controlled material removal in tight or contoured areas. It spins on a 1/4-inch shank and is rated to a maximum of 35,620 RPM, giving it a solid operating envelope for die grinders and rotary tools used in fabrication and maintenance environments.

This mounted point is used in metalworking, tool-and-die, welding cleanup, and general industrial maintenance applications. Its ball shape allows access to concave surfaces, weld joints, ports, and recessed areas that flat or cylindrical wheels cannot reach. It is a practical choice for machinists, maintenance technicians, and metalworkers who need consistent, repeatable stock removal or surface preparation on a small scale.

Key Features

• A25 ball-shape point for access to concave and contoured surfaces
• Aluminum oxide abrasive material for general-purpose grinding on steel and hard metals
• Medium grade and medium density for balanced cutting and finish quality
• Unitized bond construction for consistent performance through the life of the point
• 1/4-inch shank diameter fits standard die grinder collets
• Maximum RPM of 35,620 for use with high-speed rotary tools

Compatibility

Designed for use with standard die grinders and rotary tools accepting a 1/4-inch shank. Suitable for grinding and finishing applications on ferrous metals and other hard materials where an aluminum oxide abrasive is appropriate.

Installation Notes

This mounted point is installed and removed by a licensed or trained machinist or maintenance technician using a die grinder with a compatible 1/4-inch collet. Always verify that the tool's rated RPM meets or exceeds the point's maximum RPM before mounting. Inspect the mounted point for cracks or damage before each use and do not exceed the marked maximum speed. Wear appropriate eye protection and ensure the workpiece is secured before beginning any grinding operation.
