Norton 66253160932 Surface Grinding Wheel 46 Grit

Product Description

The NORTON 66253160932 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and thermal stability during extended grinding cycles. The wheel measures 10 inches in diameter and 1 inch thick with a 3-inch arbor hole, rated to a maximum of 2,485 RPM. At 46 grit with a G hardness code and coarse grade classification, it is suited for aggressive material removal rather than finishing work. Licensed tradespeople in machining, toolroom, and fabrication environments are the primary installers and operators of this wheel.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It carries the specification designation 32A46-GVBEP and is appropriate for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The vitrified bond structure provides an open, porous matrix that aids chip clearance and reduces heat buildup, making it well-suited for horizontal spindle surface grinding applications in both production and toolroom settings.

Key Features

• Aluminum oxide abrasive for broad material compatibility including stainless, carbon steels, and cast iron
• Vitrified bond with porous structure improves chip clearance and thermal management
• 46 grit coarse grade optimized for aggressive stock removal
• G hardness code (soft rating) promotes consistent self-dressing action
• Type 1 straight wheel geometry with no recess, compatible with standard surface and cylindrical grinder spindles
• Specification: 32A46-GVBEP

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 and wheel changes must be performed by qualified grinding machine operators following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and lock out the machine before mounting or removing the wheel. Never exceed the maximum rated RPM of 2,485 and verify that the machine spindle speed is at or below this limit before operation.
