Norton 66253363915 Surface Grinding Wheel 46 Grit 14in

Product Description

The NORTON 66253363915 is a Type 1 straight surface grinding wheel engineered for heavy-duty stock removal on a wide range of ferrous and non-ferrous metals. Built with aluminum oxide abrasive grain and a vitrified bond, it delivers consistent cutting action and open-pore structure that helps prevent loading during extended grinding passes. The wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and carries a coarse 46 grit rating with an I hardness code (medium wheel hardness). Maximum operating speed is 1,800 RPM. It is sized and specified for professional surface and cylindrical grinding applications in production and tool-room environments.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46 grit makes it well matched to roughing and aggressive material removal rather than finish grinding. The series designation 32A46-IVBE identifies the exact abrasive specification for cross-referencing with grinding wheel charts and machine setup sheets.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, free-cutting action
• Coarse 46 grit removes material aggressively — suited for roughing passes on steel and iron
• Porous wheel structure reduces loading and heat buildup during extended use
• I hardness code (medium) balances wheel wear rate with cutting efficiency across varied workpiece hardness
• Type 1 straight profile fits standard surface grinder and cylindrical grinder spindle setups
• Series specification 32A46-IVBE for precise technical reference and replacement ordering

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible 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 should be performed by a qualified machine operator or maintenance technician following ANSI B11.9 and OSHA 1910.215 grinding safety standards. Always ring-test the wheel for cracks before mounting and verify that the machine spindle speed does not exceed the 1,800 RPM maximum rated speed of this wheel. Power down and lock out the grinder before changing wheels. Never force the wheel onto the spindle or exceed the rated arbor hole tolerance.
