Norton 66253262301 Surface Grinding Wheel 46 Grit 12 in

Product Description

The NORTON 66253262301 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and structural rigidity under high-load grinding conditions. The wheel measures 12 inches in diameter, 1-1/4 inches thick, with a 3-inch arbor hole, and carries a coarse 46 grit rating with an I hardness code. It is rated to a maximum of 2070 RPM. Licensed machinists, tool grinders, and surface grinding operators are the typical end users for this wheel.

This wheel is suited for surface grinding applications on a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond and porous structure help maintain free-cutting action and reduce heat buildup during extended grinding passes. It is a no-recess, non-tapered wheel and ships individually.

Key Features

• Aluminum oxide abrasive with vitrified bond for rigid, consistent grinding performance
• 46 grit coarse grade removes stock efficiently on ferrous and non-ferrous materials
• Porous wheel structure reduces heat buildup and extends wheel life
• I hardness code suits medium-hardness workpieces common in production grinding
• Type 1 straight wheel profile fits standard surface and cylindrical grinder arbors
• Specification designation 32A46-IVBE identifies bond and grade for reorder consistency

Compatibility

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

Installation Notes

Mounting and dressing of grinding wheels must be performed by a qualified machine operator or maintenance technician following ANSI B11.9 and applicable OSHA abrasive wheel 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 maximum rated RPM of 2070 printed on the blotter label.
