Norton 66252835094 Surface Grinding Wheel 6 in 60 Grit

Product Description

The NORTON 66252835094 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous metals in industrial grinding applications. Built on a vitrified bond with aluminum oxide abrasive, this wheel delivers consistent cut rates and thermal stability across a wide range of surface grinding operations. It measures 6 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and is rated to a maximum of 4140 RPM. The K hardness code and 60 grit designation place it in the medium grade range, making it well suited for moderate material removal on harder workpiece materials without excessive wheel breakdown.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in shop and production environments. It is specified for hard carbon steels, soft carbon steels, and tool steels. The 32A Type 1 series designation indicates a straight wheel profile with no recess, compatible with standard surface grinding spindle arbors. It is a common choice for tool and die shops, machine shops, and maintenance grinding operations where repeatable finish quality and controlled stock removal are required.

Key Features

• Aluminum oxide abrasive for reliable performance on carbon and tool steels
• Vitrified bond provides thermal stability and consistent grain exposure
• 60 grit medium grade for balanced material removal and surface finish
• K hardness rating supports controlled wheel wear on harder workpieces
• Type 1 straight profile with no recess fits standard surface grinder arbors
• Porous structure promotes coolant flow and reduces heat buildup during grinding

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding hard carbon steels, soft carbon steels, and tool steels. Fits standard 1-1/4 inch arbor spindles.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or grinding specialist following ANSI B11.9 safety standards. Before mounting, inspect the wheel for cracks or chips using the ring test. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 4140 RPM rating marked on the wheel. Always use the appropriate flanges and never force the wheel onto the arbor.
