Norton 66252940862 Surface Grinding Wheel 46 Grit 7in

Product Description

The NORTON 66252940862 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. It is made from aluminum oxide abrasive bonded with a vitrified bond in the 32A series, producing a porous, free-cutting structure rated at coarse grade with a G hardness code. The wheel measures 7 inches in diameter, 0.5 inches thick, and has a 1.25-inch arbor hole. Rated at a maximum of 3600 RPM, it is suited for surface grinders, cylindrical grinders, and CNC cutting tool machines operated by machinists and tool-and-die professionals.

This wheel is built for production and maintenance grinding on a wide range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its coarse 46-grit structure removes material aggressively, making it a practical choice for surface grinder setups in machine shops and industrial maintenance environments where fast stock removal is the priority.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cutting action
• 32A series specification (32A46-GVBE) — coarse grade, G hardness, porous structure
• Type 1 straight wheel profile with no recess, no taper — direct mounting compatibility
• 3600 RPM maximum speed rating for safe use on standard surface and cylindrical grinders
• Suitable for grinding stainless steel, carbon steels, tool steels, aluminum, and cast and ductile iron
• 1.25-inch arbor hole fits standard spindle configurations on common surface grinder models

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

Installation should be performed by a qualified machinist or grinding specialist. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 standards. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
