Norton 66252941938 Surface Grinding Wheel 60 Grit 7in

Product Description

The NORTON 66252941938 is a Type 1 vitrified aluminum oxide surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Rated at 3600 RPM maximum, this wheel measures 7 inches in diameter by 3/4 inches thick with a 1-1/4 inch arbor hole. The 60-grit, I-hardness (medium grade) specification positions it for general-purpose surface grinding where controlled material removal and consistent finish are required. The vitrified bond provides rigidity and porosity that supports free cutting action and efficient swarf clearing. Licensed trade professionals in machining, tool and die, and metalworking fabrication are the primary installers and operators.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and maintenance shop environments. Documented material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It performs reliably in repetitive surface grinding passes where consistent grit exposure and bond integrity across the wheel face are critical to dimensional accuracy.

Key Features

• Type 1 flat wheel profile with no recess — direct mount to standard arbors
• Aluminum oxide abrasive grain — effective on steels, cast iron, and aluminum
• Vitrified bond construction — porous structure aids coolant flow and chip clearance
• 60 grit, I hardness (medium grade) — balances stock removal rate with surface finish
• 3600 RPM maximum rated speed — compatible with standard surface and cylindrical grinder spindle speeds
• Series 32A Type 1, spec 32A60-IVBE — traceable to NORTON standard abrasive coding

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Confirmed compatible 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

Mounting and operation should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to use. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Use proper flanges and blotters as specified by the grinder manufacturer.
