Norton 66253262573 Surface Grinding Wheel 12in 46 Grit

Product Description

The NORTON 66253262573 is a Type 1 surface grinding wheel engineered for stock removal and surface finishing on a wide range of ferrous and non-ferrous metals. It measures 12 inches in diameter, 1 inch thick, and carries a 5-inch arbor hole. Built with aluminum oxide abrasive and a vitrified bond, the wheel delivers consistent cutting action and open structure suited to coarse-grade material removal. Rated at a maximum of 2070 RPM, it is designed for use on surface grinders and cylindrical grinders in production and toolroom environments. The K hardness code indicates a medium wheel hardness rating, balancing grain retention with controlled breakdown during cut.

This wheel fits production grinding applications where coarse stock removal is required on hard and soft carbon steels, tool steels, 400 series stainless steel, aluminum, cast iron, ductile iron, and gray iron. It is suited to CNC cutting tool machines, cylindrical grinders, and surface grinders. The 32A series designation and vitrified bond make it a dependable choice for high-volume grinding operations where wheel integrity and cut consistency matter across a full shift.

Key Features

• Aluminum oxide abrasive for reliable cutting action on steel, iron, and aluminum
• Vitrified bond provides structural rigidity and consistent grain exposure
• Coarse 46-grit rating optimized for aggressive stock removal
• Porous structure aids coolant flow and chip clearance during cut
• No recess, no taper — straightforward Type 1 flat wheel geometry
• Specification code 32A46-KVBE for precise cross-reference and ordering

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron as stated by the manufacturer.

Installation Notes

Wheel mounting must be performed by a qualified grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum of 2070 RPM. Flanges must be clean and properly fitted to the 5-inch arbor bore before the wheel is secured.
