Norton 66260392461 Diamond Mounted Point 200/230 Grit

Product Description

The NORTON 66260392461 is an electroplated diamond mounted point designed for precision grinding, deburring, and finishing on hard and brittle materials. Built in a cylinder profile (Point Shape Code 1050FD), this mounted point features a single layer of diamond abrasive bonded directly to the steel shank via electroplating, delivering consistent cutting action and long service intervals between dressings. At 200/230 grit, it falls in the fine grade range, making it appropriate for work where surface finish quality matters as much as stock removal. The 0.1-pound unit fits standard die grinders and rotary tools accepting a 0.125-inch shank.

This mounted point is used in tool-and-die work, carbide tooling maintenance, ceramics finishing, glass grinding, and precision metalworking applications where conventional abrasives wear too quickly or fail to hold geometry. It is suited for both bench-mounted rotary tools and handheld die grinders in maintenance, repair, and production environments. Licensed trades and skilled machinists working with hardened steels, tungsten carbide, ceramic composites, and similar materials will find it a practical consumable for detail work in tight clearances.

Key Features

• Electroplated diamond bond for consistent grit exposure and no-dress operation
• 200/230 grit fine grade for finish grinding and light material removal
• Cylinder point shape (1050FD) maintains geometry in bores, slots, and contoured surfaces
• 0.125-inch shank diameter fits standard die grinder and rotary tool collets
• 0.050-inch head diameter enables access to narrow grooves and small-diameter features
• Single-piece steel shank construction keeps runout low at operating speeds

Compatibility

Designed as an OEM-style consumable for use in die grinders and rotary tools accepting a 0.125-inch diameter shank. Suitable for grinding carbide, hardened steel, glass, ceramic, and other hard or brittle substrates.

Installation Notes

Installation and use should be performed by machinists, tool-and-die technicians, or similarly qualified trades familiar with rotary abrasive tooling. Always confirm the spindle speed rating of the host tool does not exceed the maximum RPM rating for the mounted point before operation. Inspect the shank for runout or damage before seating in the collet, and tighten the collet to the tool manufacturer's specification. Wear appropriate eye protection and follow ANSI B7.1 safety standards for abrasive wheel use.
