Grier Abrasives A2-J1-19800 Mounted Cone Abrasive Point

Product Description

The GRIER ABRASIVES A2-J1-19800 is a rubberized, mounted abrasive point in an A2 cone shape designed for precision grinding, deburring, and surface finishing in tight spaces and contoured areas. Built with aluminum oxide abrasive and rated at a coarse grade with 46 grit, it removes material quickly and handles general-purpose grinding on metal, castings, and welds. The point mounts on a 1/4-inch shank and is sized at 1 inch maximum diameter with an overall length of 2.25 inches, making it well suited for use in die grinders and rotary tools. Machinists, fabricators, and tool-and-die professionals are the primary installers and users of this type of mounted point.

This abrasive point is used in metal fabrication shops, foundries, maintenance facilities, and job sites where a die grinder or rotary tool is the primary equipment. It is suited for deburring drilled holes, blending weld seams, cleaning up casting flash, and shaping or smoothing metal components in areas that are difficult to reach with larger abrasive tools. The coarse grit makes it most effective for aggressive stock removal rather than fine finishing work.

Key Features

• A2 cone point shape for reaching contoured surfaces and recessed areas
• Aluminum oxide abrasive material for effective grinding on ferrous and non-ferrous metals
• Coarse grade, 46 grit for aggressive stock removal and fast material cut rate
• Regular hardness rating provides consistent performance across general grinding applications
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Rated to 38,200 RPM maximum operating speed

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank mounted abrasive point.

Installation Notes

Mounted abrasive points are installed and operated by machinists, fabricators, and maintenance technicians using die grinders or compatible rotary tools. Always ensure the tool is powered off and unplugged before inserting or removing the mounted point from the collet. Do not exceed the rated maximum of 38,200 RPM, and inspect the point for cracks or damage before each use. Eye protection and appropriate PPE are required whenever operating abrasive tooling.
