Norton 66252942416 Toolroom Grinding Wheel 7x1x1.25 in

Product Description

The NORTON 66252942416 is a Type 01 straight toolroom grinding wheel built for precision grinding applications in machine shops and toolrooms. Identified by the specification code 39C120-IVK, this wheel measures 7 inches in diameter, 1 inch wide, and carries a 1.25-inch arbor bore. The 39C designation indicates a green silicon carbide abrasive, and the 120 grit rating places it in the fine range, suited for finishing and sharpening operations on carbide tooling, ceramics, and similar hard materials. Licensed machinists, tool grinders, and toolroom technicians are the primary installers and operators of this wheel.

This wheel is designed for use on bench grinders and pedestal grinders configured for toolroom service. It is commonly used for sharpening carbide-tipped cutting tools, drills, reamers, and other hard metal or ceramic workpieces that require a fine surface finish. The Type 01 flat wheel profile is the standard configuration for straight surface and tool-face grinding. It is appropriate for light-to-moderate stock removal at the fine grit level, making it a finishing wheel rather than a rough shaping wheel.

Installation Notes

Grinding wheel mounting must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Before mounting, power down and lock out the grinder per applicable OSHA lockout-tagout procedures. Always ring-test the wheel for cracks prior to installation and use the correct flanges and blotters as specified by the wheel manufacturer. Operate the wheel within its rated maximum RPM and use appropriate eye protection and guarding at all times.
