Norton 69936662110 Surface Grinding Wheel 60 Grit 8 in

Product Description

The NORTON 69936662110 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous metals. It measures 8 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole, and runs at a maximum rated speed of 3600 RPM. The wheel is constructed with aluminum oxide abrasive grain bonded in a vitrified matrix, producing a medium-grade, J-hardness wheel that self-dresses predictably under load. The 48A60-JVBE specification identifies it as a 60-grit, ruby-colored wheel suited to flat surface grinding applications. Licensed machinists, tool-and-die technicians, and grinding specialists install and operate this wheel on stationary grinding equipment.

This wheel is intended for surface grinding operations on hard carbon steels, soft carbon steels, and tool steels. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond provides rigidity and consistent form-holding during wet or dry operation, making it appropriate for both coolant-assisted precision grinding and dry roughing passes where heat dissipation is managed by feed rate and depth of cut.

Key Features

• Aluminum oxide abrasive grain — effective on carbon steels and tool steels
• Vitrified bond for rigid, consistent form-holding and free-cutting action
• 60 grit, J hardness (medium grade) balances material removal rate with finish quality
• Rated to 3600 RPM maximum operating speed
• Type 1 flat wheel geometry — no recess, no taper
• Wet and dry operation compatible

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding hard carbon steels, soft carbon steels, and tool steels. Fits machines accepting an 8-inch diameter, 1.25-inch arbor hole wheel.

Installation Notes

Wheel mounting and dressing must be performed by a qualified machinist or grinding specialist following ANSI B11.9 safety standards for grinding machines. Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum operating speed of 3600 RPM. Use flanges of appropriate size and ensure the blotter gaskets are seated correctly before tightening the arbor nut.
