Norton 66253246819 Surface Grinding Wheel 16x2x5 60 Grit

Product Description

The NORTON 66253246819 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous metals. Measuring 16 inches in diameter, 2 inches thick, with a 5-inch arbor hole, this wheel operates at a maximum of 2,030 RPM. At 60 grit with a K hardness code and medium grade designation, it delivers an aggressive yet controlled cut suited for production surface grinding where flatness and finish consistency are required. Licensed HVAC, machining, and tool-room professionals specify this wheel for high-volume material removal on surface and cylindrical grinders.

This wheel is rated for use on CNC cutting tool machines, cylindrical grinders, and surface grinders in both shop and production environments. Its material application range covers 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron, making it a versatile single-wheel solution for mixed-metal grinding operations. The vitrified bond provides consistent grain exposure throughout the wheel life, maintaining cut rate as the wheel wears down.

Compatibility

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

Grinding wheel mounting and dressing should be performed by a qualified machinist or tool-room professional following ANSI B11.9 safety standards for grinding machines. Always verify the machine spindle speed does not exceed the wheel maximum of 2,030 RPM before mounting. Inspect the wheel for cracks or chips using a ring test before installation, and ensure the arbor hole fits the spindle without forcing. Never operate a grinding wheel without appropriate guarding in place.
