Norton 61463616473 Mounted Point W221 24 Grit Zirconia

Product Description

The NORTON 61463616473 is a cylinder-shape mounted point abrasive designed for aggressive stock removal on metal, weld seams, castings, and hard-to-reach internal surfaces. It uses a zirconia alumina abrasive grain bonded with a resinoid bond, making it well-suited for high-pressure grinding where heat and wear resistance matter. The point measures 1.5 inches thick, mounts on a 0.25-inch diameter shank with a 1.5-inch shank length, and is rated to a maximum of 24,490 RPM. At 24 grit, this is a very coarse cutting tool intended for rapid material removal rather than finishing work. Fabricators, welders, and tool-and-die workers are the typical end users.

This mounted point is used in die grinders and rotary tools for grinding internal bores, contoured surfaces, ports, and recesses where flat or cup wheels cannot reach. The W221 cylinder shape provides a broad flat face and side grinding capability in a single tool. Common applications include weld cleanup on pipe and structural steel, deburring cast iron and steel components, and surface prep on hard alloys. The very coarse 24-grit cut rate makes it a roughing tool; follow with finer grits if a smoother finish is required.

Key Features

• Zirconia alumina grain for durable, high-stock-removal grinding on ferrous metals and hard alloys
• 24 grit very coarse grade for fast, aggressive material removal in roughing operations
• Resinoid bond provides flexibility and resistance to heat generated during high-pressure grinding
• W221 cylinder shape offers both face and side grinding capability in confined areas
• 0.25-inch shank diameter fits standard die grinder and rotary tool collets
• 24,490 RPM maximum speed rating supports use in typical pneumatic and electric die grinders

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25-inch shank. Verify that the tool spindle speed does not exceed the 24,490 RPM maximum rated speed of this mounted point before use.

Installation Notes

Installation is performed by metalworkers, fabricators, and machinists using a standard die grinder with a 0.25-inch collet. Before mounting, confirm the tool is disconnected from its air supply or power source and the collet is clean and undamaged. Insert the shank fully into the collet and tighten securely before operating. Always verify the grinder RPM rating does not exceed the 24,490 RPM maximum marked on this abrasive, and use appropriate eye protection and guarding per ANSI B7.1 standards.
