Norton 66260273597 Surface Grinding Wheel 6in 150 Grit

Product Description

The NORTON 66260273597 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding applications in industrial and toolroom environments. Built with a synthetic diamond abrasive and a resinoid bond, this wheel delivers consistent material removal and a very fine finish on hard, brittle, and difficult-to-grind materials such as carbide, ceramics, and hardened steels. It measures 6 inches in diameter, 1/16 inch thick, with a 1-1/4 inch bore, and carries a 150 grit rating at very fine grade. The wheel is rated for wet operation and features a 1/4 inch superabrasive depth with a concentration of 100, supporting both roughing and finishing passes in a single setup.

This wheel is suited for surface grinding operations in machine shops, tool and die facilities, and production grinding environments where tight tolerances and clean surface finishes are required. The Type 1A1 straight wheel profile fits standard surface grinding spindles and is appropriate for grinding carbide tooling, ceramic components, and other superhard materials. It is installed and operated by machinists and grinding technicians following wheel and machine manufacturer speed and dressing guidelines.

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for surface grinders accepting a Type 1A1 straight wheel with a 6 inch diameter and 1-1/4 inch bore.

Installation Notes

Surface grinding wheels must be installed by qualified machinists or grinding technicians following ANSI B7.1 safe use guidelines. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to installation. Power down and lock out the grinder before changing wheels, and confirm that the machine RPM rating meets or exceeds the wheel speed rating. Never exceed the maximum operating speed marked on the wheel.
