Norton 66253160758 Surface Grinding Wheel 46 Grit 10 in

Product Description

The NORTON 66253160758 is a Type 1 surface grinding wheel designed for stock removal and precision surface finishing on ferrous and non-ferrous metals. Built on a vitrified bond with an aluminum oxide abrasive, it measures 10 inches in diameter and 1 inch thick, with a 3-inch arbor hole. The 46-grit, Coarse grade cuts aggressively while the K hardness rating (medium) provides enough bond retention to maintain wheel integrity across a wide range of workpiece materials. At a maximum operating speed of 2,485 RPM, this wheel is suited for production grinding environments where consistent material removal is the priority. Grinding wheel installation and operation must follow ANSI B7.1 safety standards.

This wheel is rated for use on 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A series specification (32A46-KVBE) identifies this as a Norton manufactured aluminum oxide wheel with a vitrified bond and porous structure, making it appropriate for both wet and dry surface grinding applications where chip clearance and coolant flow matter.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous and non-ferrous materials
• Vitrified bond with porous structure promotes coolant flow and chip clearance
• 46 grit Coarse grade for aggressive stock removal
• K hardness (medium) bond retains abrasive without loading on varied workpiece hardnesses
• Type 1 flat wheel, no recess, no taper — straightforward mounting on standard flanges
• Norton 32A series specification: 32A46-KVBE

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for 400 Series stainless, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheels must be installed by qualified personnel following ANSI B7.1 safety standards and the machine manufacturer's mounting instructions. Always power down and lock out the grinder before mounting or removing a wheel. Perform a ring test before installation and run the wheel at operating speed in a guarded area for at least one minute before applying it to a workpiece. Never exceed the maximum rated speed of 2,485 RPM.
