Norton 66253160900 Surface Grinding Wheel 60 Grit 10 in

Product Description

The NORTON 66253160900 is a Type 1 vitrified aluminum oxide surface grinding wheel designed for precision stock removal on ferrous metals. Built to the 38A series specification, it features a 60-grit, medium-grade abrasive structure with a K hardness code and a semi-friable grain that self-sharpens under load. The wheel measures 10 inches in diameter by 1 inch thick with a 3-inch arbor hole, and it carries a maximum operating speed of 2,485 RPM. Licensed HVAC, machine tool, and metalworking technicians will find this wheel suited for high-precision flat and angular surface grinding applications where consistent cut rate and wheel life are required.

This wheel is rated for use on soft carbon steels, tool steels, and super alloys. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The non-porous, non-tapered, no-recess Type 1 flat wheel profile makes it a direct fit for standard machine spindle setups common in production and toolroom environments. The white aluminum oxide abrasive is well suited for heat-sensitive materials where minimizing workpiece burn is a priority.

Key Features

• 38A series aluminum oxide abrasive rated for soft carbon steels, tool steels, and super alloys
• 60 grit, K hardness code, medium grade for balanced stock removal and wheel life
• Semi-friable grain structure promotes consistent self-sharpening during use
• Vitrified bond provides rigid, precise cutting action on flat and angular surfaces
• Type 1 flat profile with no recess and no taper for direct spindle mounting
• Maximum rated speed of 2,485 RPM

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Fits standard 3-inch arbor spindle configurations on Type 1 wheel-compatible machines.

Installation Notes

Installation should be performed by qualified machine operators or maintenance technicians following ANSI B7.1 safe use guidelines for abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM of 2,485. Flanges, blotters, and mounting hardware must be in good condition and correctly sized for a 3-inch arbor and 10-inch wheel.
