Norton 66253019356 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253019356 is a Type 1 surface grinding wheel designed for precision material removal on soft carbon steels, tool steels, and super alloys. Built with aluminum oxide abrasive and a vitrified bond, this wheel carries a 60 grit, medium grade specification rated for both wet and dry operation. At 8 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, it is sized for standard surface and cylindrical grinding applications. The wheel is rated to a maximum of 3600 RPM and falls under NORTON series specification 25A60-HVP2. Hardness code H and a semi-friable grain structure make it a workable choice for controlled stock removal across a range of ferrous workpieces.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The porous, vitrified bond structure promotes chip clearance and coolant flow, making it appropriate for wet grinding setups where heat management and surface finish consistency are priorities. Licensed machinists and tool-and-die professionals are the typical installers for this type of abrasive wheel.

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting an 8 inch diameter Type 1 wheel with a 1-1/4 inch arbor hole running at or below 3600 RPM.

Installation Notes

Abrasive wheel mounting must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the maximum rated RPM of 3600. Ensure the machine guard is properly in place before powering the grinder.
