Norton 61463624474 Mounted Point B124 90 Grit Fine

Product Description

The NORTON 61463624474 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Shaped as a ball (point shape code B124), it runs at up to 91,770 RPM and delivers a fine, 90-grit cut on ferrous and non-ferrous metals, hardened steel, and cast iron. The hard vitrified bond holds the abrasive grain firmly during high-speed rotary tool use, making it a dependable choice for die grinders, rotary tools, and bench grinders with the appropriate collet. Licensed tradespeople and machining professionals reach for this style of mounted point when internal radii, ports, or irregular surfaces require controlled stock removal.

This mounted point is suited for tool-and-die work, mold finishing, weld cleanup, and general precision grinding tasks in both shop and field environments. Its compact ball geometry allows access to bores, cavities, and curved profiles that flat or cylindrical wheels cannot reach. The 1/8-inch shank is a standard size compatible with most die grinder and rotary tool collets used in metalworking and maintenance trades.

Key Features

• Ball profile (B124) accesses curved surfaces, bores, and contoured cavities
• 90-grit fine grade removes material while leaving a relatively smooth finish
• Aluminum oxide abrasive for use on steel, cast iron, and general ferrous metals
• Vitrified bond provides hard, rigid grain retention at high RPM
• Rated to 91,770 RPM for use with standard die grinders and rotary tools
• 1/8-inch shank diameter fits widely available collets without adapters

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8-inch collet. Suitable for grinding ferrous metals, hardened steel, and cast iron in tool-and-die, mold, and maintenance applications.

Installation Notes

This mounted point is installed and removed by a machinist, toolroom technician, or maintenance mechanic using the collet wrench appropriate for the host tool. Always confirm the tool spindle speed does not exceed the 91,770 RPM rating before operation. Inspect the mounted point for cracks or chips before each use and discard any damaged piece. Wear appropriate PPE including eye protection and ensure the work area is clear of personnel before engaging the tool.
