Norton 66253043729 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043729 is a Type 1 surface grinding wheel designed for precision flat grinding on ferrous and non-ferrous workpieces. Measuring 8 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, this wheel is built around an aluminum oxide abrasive grain bonded with a vitrified bond system. It carries a 60 grit, medium grade, K hardness rating — a specification that suits general-purpose stock removal on a wide range of steels, cast irons, and aluminum. Rated to a maximum of 3600 RPM, this wheel is appropriate for use by machinists and tool grinders working on surface or cylindrical grinding equipment.

This wheel is suited for surface grinding operations in machine shops, tool rooms, and manufacturing environments handling both production and maintenance work. Material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The straight Type 1 form with no recess and no taper makes it straightforward to mount and dress on standard spindle configurations.

• Rated to 3600 RPM maximum operating speed
• Compatible with multiple workpiece materials including stainless, carbon steels, tool steels, aluminum, and cast iron
• Series designation 32A60-KVBE for direct cross-reference in shop records and procurement

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator in accordance with ANSI B11.9 grinding safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to use. Power down and lockout the grinder before changing wheels. Never exceed the maximum rated RPM of 3600 under any operating condition.
