Norton 66253044195 Surface Grinding Wheel 46 Grit 8 in

Product Description

The NORTON 66253044195 is a Type 1 surface grinding wheel engineered for stock removal and surface finishing on a range of ferrous and non-ferrous metals. Built to the 32A46-GVBEP specification, it uses aluminum oxide abrasive in a vitrified bond matrix, delivering consistent cut rate and predictable breakdown across the wheel face. The wheel measures 8 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. It is rated at a maximum of 3,105 RPM and carries a coarse grade, G hardness code, making it suitable for aggressive material removal on harder workpiece materials. Licensed machinists, tool grinders, and CNC machine operators are the primary users.

This wheel is used in precision surface grinding and cylindrical grinding applications across job shops, tool rooms, and production machining environments. It handles 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its porous vitrified bond resists loading on gummy materials like aluminum and softer irons, maintaining a free-cutting action through the grind cycle. The 8-inch diameter is a common fit for benchtop and floor-standing surface grinders as well as cylindrical grinding machines used in toolroom and CNC environments.

Key Features

• 32A46-GVBEP specification: aluminum oxide abrasive with vitrified bond for consistent, controlled stock removal
• Coarse 46 grit for aggressive cutting on hard and soft carbon steels, stainless, and cast iron
• Porous wheel structure resists loading on aluminum and softer workpiece materials
• G hardness (soft) rating allows the wheel to shed dull grains and maintain cutting efficiency
• No recess, no taper — standard Type 1 flat wheel geometry for straightforward mounting
• Rated to 3,105 RPM maximum operating speed

Compatibility

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

Wheel mounting should be performed by a qualified machinist or grinder operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down the machine and confirm zero energy state before changing wheels. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Conduct a ring test per ANSI B7.1 and run the wheel at operating speed for at least one minute behind a guard before presenting work.
