Norton 66252941935 Surface Grinding Wheel 46 Grit 7in

Product Description

The NORTON 66252941935 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with an aluminum oxide abrasive grain and a vitrified bond, it delivers consistent cutting action and good form-holding throughout the wheel's life. The wheel measures 7 inches in diameter by 0.75 inches thick with a 1.25-inch arbor hole, making it a standard fit for most surface and cylindrical grinders. At 46 grit with a K hardness code (medium grade), it is suited for coarse material removal on harder workpiece materials. Maximum operating speed is 3600 RPM. Weight is approximately 2.38 pounds.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and machine-shop environments. It is rated for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse grit makes it a practical choice when rapid material removal takes priority over fine surface finish. Installation is performed by qualified machine operators or tool-room technicians.

Key Features

• Aluminum oxide abrasive grain for broad metal compatibility including stainless and tool steels
• Vitrified bond provides rigid support and consistent wheel form during grinding passes
• 46 grit coarse grade suited for aggressive stock removal applications
• K hardness (medium) helps resist grain pullout on harder workpiece materials
• Type 1 flat wheel profile with no recess and no taper — standard fitment geometry
• 3600 RPM maximum rated speed; porous structure aids in coolant retention and chip clearance

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Conforms to series designation 32A Type 1 per Norton specifications (spec code 32A46-KVBE).

Installation Notes

Grinding wheel mounting should be performed only by trained personnel following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Power down and lock out the machine before mounting or changing a wheel. Perform a ring test before mounting, inspect the wheel for cracks or chips, and use proper flanges and blotters as specified by the grinder manufacturer. Never exceed the maximum rated RPM of 3600 under any operating condition.
