Norton 66253262562 Surface Grinding Wheel 12in 46 Grit

Product Description

The NORTON 66253262562 is a Type 1 surface grinding wheel engineered for precision flat grinding on ferrous and non-ferrous metals. Built to the 32A series specification (32A46-HVBE), it uses an aluminum oxide abrasive grain bonded with a vitrified bond for consistent stock removal and free cutting action. The wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. At 46 grit and H hardness (coarse grade), it is designed for aggressive material removal on harder workpiece materials. Maximum operating speed is 2,070 RPM. Weight is 9.045 pounds. Licensed tradespeople and machine operators handling surface grinder setups are the primary installers of this wheel type.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production shop and maintenance environments. Rated material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its porous wheel structure promotes coolant flow and chip clearance, making it effective in wet or dry grinding operations where heat control and finish consistency are required.

Key Features

• 32A series aluminum oxide abrasive for consistent cut on ferrous and non-ferrous metals
• Vitrified bond for rigidity, thermal stability, and dressability
• 46 grit coarse grade for high material removal rates
• H hardness rating provides a balance of wheel life and free cutting action on harder workpieces
• Porous structure supports coolant penetration and chip clearance
• Type 1 straight wheel profile fits standard surface grinder and cylindrical grinder spindles

Compatibility

Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a 12-inch diameter, 3-inch arbor hole, Type 1 straight wheel. Rated for use on 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B7.1 and applicable shop safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 2,070 RPM maximum operating speed marked on the wheel.
