Norton 61463624489 Mounted Point W145 60 Grit

Product Description

The NORTON 61463624489 is a vitrified aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and hard materials. Shaped as a cylinder (W145 point shape code), this mounted point features a 60-grit, medium-grade abrasive with a vitrified bond that delivers consistent cut rate and dimensional stability under heat. The 1/8-inch shank diameter fits standard rotary tools, die grinders, and spindle-mounted applications. It is rated to a maximum of 84,190 RPM, making it suitable for high-speed grinding operations. Machinists, tool-and-die workers, and metal fabricators typically install and use this abrasive point in production and maintenance grinding tasks.

This mounted point is suited for internal grinding, cavity finishing, and contour work in both light industrial and shop environments. The cylinder profile provides flat-face contact, which is effective for reaching into bores, slots, and recessed surfaces. The vitrified bond resists loading on ferrous metals and hard alloys. The 1/8-inch shank and 1-1/2-inch shank length give adequate reach for accessing confined workpieces. It is sold individually and is appropriate for use in both bench-mounted and handheld rotary grinder setups.

Key Features

• W145 cylinder point shape for flat-face contact in bores and recessed surfaces
• 60-grit medium-grade aluminum oxide abrasive for aggressive stock removal with controlled finish
• Vitrified bond maintains shape stability and resists glazing under high heat
• Maximum rated speed of 84,190 RPM for high-speed die grinder compatibility
• 1/8-inch shank diameter fits standard collets on rotary tools and die grinders
• 1-1/2-inch shank length provides reach into confined or recessed work areas

Compatibility

Designed for use with rotary die grinders, spindle grinders, and similar tools accepting a 1/8-inch collet. Confirm tool RPM rating meets or exceeds the 84,190 RPM maximum before mounting.

Installation Notes

This abrasive point is installed by a machinist or metal fabricator using a standard collet wrench on a die grinder or rotary tool. Always verify the tool spindle speed does not exceed the 84,190 RPM maximum marked on this point before operation. Power down and disconnect the tool from the power source before mounting or removing the point. Inspect the point for cracks or chips before each use and never use a damaged abrasive on a live spindle.
