Norton 66260392479 Diamond Mounted Point 200/230 Grit

Product Description

The NORTON 66260392479 is a diamond electroplated mounted point designed for precision grinding and finishing of hard, brittle materials such as carbide, ceramics, glass, and hardened steel. Configured in a cylinder point shape (Series 1000, shape code 1060FD), this mounted point carries a fine 200/230 grit diamond abrasive bonded directly to the steel shank through an electroplating process. The electroplated bond exposes the full diamond layer immediately on first use and maintains a consistent cut rate throughout the wheel life. The 0.125 inch shank fits standard die grinder and rotary tool collets, making this a practical choice for tool-and-die work, mold finishing, and deburring operations performed by machinists, toolmakers, and maintenance technicians.

This mounted point is suited for use in toolroom, production grinding, and maintenance repair applications involving hard substrates that conventional abrasive wheels cannot effectively address. The cylinder geometry provides flat-face and side-grinding capability, useful when working inside bores, slots, or recessed surfaces that require controlled stock removal. Typical applications include grinding carbide inserts, sharpening carbide-tipped tooling, finishing ceramic components, and deburring hardened steel parts. The silver electroplated construction handles dry and light-coolant grinding conditions.

Key Features

• Diamond abrasive for grinding carbide, ceramics, glass, and hardened steel
• Electroplated bond delivers immediate cutting action with no break-in period
• Cylinder point shape (1060FD) supports flat-face and side-grinding in confined areas
• Fine 200/230 grit for smooth finishing and controlled stock removal
• 0.125 inch shank fits standard die grinder and rotary tool collets
• Compact overall length of 2.25 inches for use in restricted access areas

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.125 inch shank collet. Suitable for grinding carbide, ceramics, glass, stone, and hardened steel workpieces.

Installation Notes

Mounted points must be installed in a collet sized to match the 0.125 inch shank diameter — a loose or oversized collet will cause runout and premature wear. Inspect the mounted point for cracks or chips before mounting and do not use a damaged point. Ensure the tool spindle speed does not exceed the maximum RPM rating marked on the point or packaging. Eye protection and appropriate personal protective equipment are required when operating any grinding accessory.
