Norton 66252941930 Surface Grinding Wheel 46 Grit 7 in

Product Description

The NORTON 66252941930 is a Type 1 surface grinding wheel engineered for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Constructed from aluminum oxide abrasive with a vitrified bond, this wheel measures 7 inches in diameter, 3/4 inches thick, and carries a 1-1/4 inch arbor hole. The 46-grit, coarse-grade specification removes material aggressively while the H hardness code (soft rating) supports consistent wheel breakdown and self-sharpening action. Rated to 3600 RPM maximum, it is suited for grinding operations on ferrous and non-ferrous metals in production shop and maintenance environments. The series designation is 32A46-HVBE. Installation and use require a licensed or qualified machine operator following applicable shop safety standards.

This wheel is designed for material removal applications across a wide range of metals. Documented material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its porous, vitrified-bond construction promotes coolant flow and chip clearance during wet or dry grinding operations on surface and cylindrical grinding equipment. It is a practical replacement wheel for production toolrooms, maintenance shops, and CNC grinding cells where consistent stock removal on both ferrous and non-ferrous workpieces is required.

Key Features

• Type 1 flat wheel profile with no recess, compatible with standard surface and cylindrical grinder spindles
• Aluminum oxide abrasive with vitrified bond provides durability and consistent cut rate
• 46 grit coarse grade for aggressive stock removal on a broad range of metals
• Porous wheel structure promotes coolant penetration and chip clearance
• H hardness code (soft rating) encourages controlled wheel breakdown and sharp abrasive exposure
• Maximum operating speed of 3600 RPM

Compatibility

Documented compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. Documented 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 and dressing should be performed by a qualified machine operator or tool-room technician following ANSI B11 and OSHA 1910.215 general industry standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM stamped or marked on the wheel or packaging. Proper flanges, blotters, and a correctly fitted arbor bushing are required for safe operation.
