Norton 66253043734 Surface Grinding Wheel 80 Grit 8 in

Product Description

The NORTON 66253043734 is a Type 1 straight surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and open wheel structure suited for surface, cylindrical, and CNC cutting tool machine applications. The wheel measures 8 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole, and is rated for a maximum of 3,600 RPM. At medium grade with an I hardness code and 80 grit, it balances material removal rate with surface finish quality. Weighing approximately 2.09 pounds, it is installed by tool room machinists and grinding machine operators.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and tool room environments. It is rated for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure of the wheel helps clear chips and reduce heat buildup during extended grinding passes, making it a practical choice for shops working across a range of ferrous and non-ferrous workpiece materials.

Key Features

• No recess, no taper Type 1 straight wheel configuration
• Series specification 32A80-IVBE for direct cross-reference sourcing

Compatibility

Rated 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 workpieces.

Installation Notes

Installation should be performed by a qualified machine operator or tool room technician following the grinder manufacturer's mounting instructions and applicable 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 before each use and perform a ring test to confirm integrity. Never exceed the 3,600 RPM maximum speed rating stamped or labeled on the wheel.
