Norton 66253262107 Surface Grinding Wheel 60 Grit 12in

Product Description

The NORTON 66253262107 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous metals. Constructed with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and thermal stability throughout the grinding cycle. The wheel measures 12 inches in diameter, 1/2 inch thick, and carries a 5-inch arbor hole, making it sized for industrial surface grinders and cylindrical grinders. At 60 grit with K hardness (medium grade), it balances aggressive material removal with acceptable surface finish on production workpieces. Maximum operating speed is 2070 RPM. Rated weight is 3.99 pounds.

This wheel is suited for surface grinding and cylindrical grinding operations in job shops, tool rooms, and production grinding cells. It is appropriate for use on 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 and CNC cutting tool machines. The porous structure of the vitrified bond allows coolant penetration and chip clearance, reducing heat buildup during aggressive passes on hardened steels and cast materials.

Key Features

• Aluminum oxide abrasive grain for broad metal compatibility including stainless and carbon steels
• Vitrified bond with porous structure supports coolant flow and chip clearance
• 60 grit, K hardness (medium grade) balances stock removal rate and surface quality
• Type 1 flat wheel with no recess — straightforward mounting on standard arbors
• 5-inch arbor hole fits common industrial surface and cylindrical grinder spindles
• Series designation 32A60-KVBE provides positive identification for reorder and compliance documentation

Compatibility

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

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified operator or machinist following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Always inspect the wheel for cracks or chips before mounting — perform a ring test per ANSI standards. Power down and lock out the grinder before changing wheels. Never exceed the 2070 RPM maximum operating speed marked on this wheel; confirm the machine spindle speed before starting the grinder.
