Norton 66260392551 Diamond Mounted Point 200/230 Grit

Product Description

The NORTON 66260392551 is a diamond electroplated mounted point designed for precision grinding, deburring, and finishing on hard and brittle materials. Part of the Series 1000 electroplated line, this mounted point uses industrial diamond abrasive bonded directly to the steel shank through an electroplating process, delivering consistent cut performance and a long service life on materials such as carbide, ceramics, glass, and hardened steel. The cylinder profile and fine 200/230 grit rating make it well-suited for detail work and tight-tolerance surface finishing. It weighs 0.1 pounds and fits a standard 0.125-inch collet or die grinder chuck.

This mounted point is used in tool-and-die shops, maintenance facilities, and production grinding operations where tight access or contoured surfaces require a small-diameter abrasive. Common applications include finishing carbide tooling, grinding ceramic components, cleaning up weld joints on hardened surfaces, and deburring precision bored holes. The cylinder geometry provides flat-faced contact for consistent stock removal on flat, concave, and step surfaces. It is typically installed in a rotary die grinder, flex-shaft machine, or CNC tool grinder.

Key Features

• Diamond abrasive electroplated construction for consistent cut on carbide, ceramic, and hardened materials
• Fine 200/230 grit for precision surface finishing and tight-tolerance work
• Cylinder point shape (code 1100FD) provides flat-face contact on a range of surface geometries
• 0.125-inch shank diameter fits standard die grinder collets and flex-shaft chucks
• Compact 0.1-inch head diameter allows access to confined areas and small-bore features
• Silver finish; overall length of 2.25 inches for extended reach in deep cavity work

Compatibility

Designed for use with rotary die grinders, flex-shaft machines, and tool grinders accepting a 0.125-inch shank mounted point.

Installation Notes

Installation is performed by machinists, tool grinders, and maintenance technicians using a die grinder or compatible rotary tool. Secure the 0.125-inch shank fully into the collet and tighten per the tool manufacturer specifications before operation. Always verify that the spindle RPM rating of the host tool does not exceed the rated speed of the mounted point. Wear appropriate eye protection and ensure the workpiece is properly fixtured before grinding.
