Norton 66252942213 Surface Grinding Wheel 46 Grit 7 in

Product Description

The NORTON 66252942213 is a Type 5 recessed surface grinding wheel engineered for aggressive stock removal on ferrous and non-ferrous metals. Built on a vitrified bond with aluminum oxide abrasive, it runs at a maximum of 3600 RPM and delivers coarse-grade cutting action suited to production grinding applications. The wheel measures 7 inches in diameter and 0.75 inches thick, with a 1.25-inch arbor hole and a one-side recess measuring 2.75 inches in diameter and 0.25 inches deep. Licensed HVAC, fabrication, and machine-shop professionals recognize the 32A specification as a reliable general-purpose formulation for consistent wheel life and surface finish control.

This wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use with cylindrical grinders and surface grinders in shop or production environments. The J hardness rating and 46 grit size position it for operators who need fast material removal while retaining adequate wheel integrity across extended runs on demanding base materials.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cut
• Coarse 46 grit with J hardness for aggressive stock removal on hard metals
• Type 5 recessed profile with one-side recess for clearance on surface grinder spindles
• Rated to 3600 RPM maximum operating speed
• Gray wheel color; non-tapered, non-friable construction
• Specification code 32A46-JVBE identifies abrasive series, grit, hardness, and bond

Compatibility

Designed for use with cylindrical grinders and surface grinders. Rated for material applications including 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 operator following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines for abrasive wheel machinery. Before mounting, ring-test the wheel for cracks and confirm the spindle speed does not exceed the 3600 RPM maximum stamped on the wheel. Use proper flanges and a compressible blotter between the flange and wheel face. Never force the wheel onto the spindle or alter the arbor hole diameter.
