Norton 66253160898 Surface Grinding Wheel 60 Grit Type 1

Product Description

The NORTON 66253160898 is a Type 1 surface grinding wheel engineered for precision stock removal on soft carbon steels, tool steels, and super alloys. It measures 10 inches in diameter by 1 inch thick with a 3-inch arbor hole, and runs at a maximum of 2,485 RPM. The wheel is made from aluminum oxide abrasive bonded in a vitrified bond matrix, producing a white, non-porous, semi-friable wheel rated at I hardness (medium grade). Series designation 38A60-IVBE provides a consistent reference for reorder and specification matching. Licensed trades and precision grinding shops rely on this wheel for flat surface and plunge grinding operations where controlled cut rate and wheel life both matter.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and tool-room environments. Its 60-grit, medium-grade profile strikes a balance between material removal rate and surface finish quality, making it a practical choice for general-purpose ferrous grinding applications including soft carbon steels and tool steels. The aluminum oxide abrasive also performs on super alloys where controlled heat generation is a priority.

Key Features

• Type 1 straight wheel profile with no recess and no taper — standard fitment for most surface and cylindrical grinder spindles
• 60 grit, I hardness (medium grade) aluminum oxide abrasive for balanced stock removal on ferrous metals
• Vitrified bond construction provides rigidity and consistent grit exposure throughout wheel life
• Semi-friable abrasive self-sharpens during use, reducing the frequency of dressing cycles
• Non-porous structure limits loading when grinding soft carbon steels and super alloys
• Series 38A specification provides a precise reorder reference for shops managing tooling standards

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Material applications include soft carbon steels, tool steels, and super alloys. Verify spindle speed rating meets or exceeds 2,485 RPM maximum and that the 3-inch arbor bore matches the machine spindle before mounting.

Installation Notes

Installation should be performed by a qualified grinding machine operator or maintenance technician following ANSI B7.1 safe wheel handling and mounting standards. De-energize and lock out the grinder before mounting or removing the wheel. Always perform a ring test before mounting and run the wheel at operating speed with the guard in place for at least one minute before bringing it into contact with the workpiece. Never exceed the rated maximum RPM of 2,485.
