Grier Abrasives A25-S5-17835 Mounted Point Ball Fine

Product Description

The GRIER ABRASIVES A25-S5-17835 is a ball-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on hard materials. Built with a silicon carbide abrasive grain and a unitized bond, this mounted point delivers consistent stock removal in a soft density that conforms well to contoured surfaces. It runs at a maximum of 35,620 RPM and mounts on a 1/4-inch shank, making it compatible with standard die grinders and rotary tools used in fabrication and metalworking environments. The fine grade and green color coding identify it as a finishing-stage abrasive suited to controlled material removal.

This mounted point is used in metalworking, tool and die, welding cleanup, and light manufacturing applications where internal bores, cavities, and irregular profiles need grinding or finishing. The A25 ball shape is well suited for working inside curved surfaces, chamfers, and recesses that flat or cylindrical points cannot reach. It is a common choice for machinists, fabricators, and maintenance technicians performing precision hand-tool grinding work on ferrous and non-ferrous metals as well as some ceramics and composites.

Key Features

• Ball (A25) point shape for access to curved recesses and internal profiles
• Silicon carbide abrasive grain for hard material grinding and finishing
• Fine grade provides controlled stock removal with a smoother finish surface
• Soft density unitized bond conforms to workpiece contours
• 1/4-inch shank diameter fits standard die grinders and rotary tools
• Maximum rated speed of 35,620 RPM for high-speed rotary tool use

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank mounted point. Suitable for grinding and finishing applications on hard metals, ceramics, and similar materials requiring a fine-grade silicon carbide abrasive.

Installation Notes

Mounting and use should be performed by qualified machinists or fabricators familiar with abrasive safety practices and applicable ANSI standards for mounted abrasives. Always inspect the mounted point for chips or cracks before use and ensure the tool spindle speed does not exceed the 35,620 RPM rating. Secure the shank fully in the collet before operating and wear appropriate eye and face protection. Never use a mounted point on a machine that cannot be confirmed within the rated RPM range.
