Norton 66253262581 Surface Grinding Wheel 12in 60 Grit

Product Description

The NORTON 66253262581 is a Type 1 surface grinding wheel engineered for high-stock-removal and precision surface finishing on ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention under sustained machine loads. At 12 inches in diameter, 1 inch thick, and with a 3-inch arbor hole, it is sized for full-size surface grinders and cylindrical grinding setups. The 60-grit, I-hardness (medium) specification positions it as a general-purpose production wheel capable of handling a wide range of material hardnesses. Rated to 2070 RPM, the wheel carries the series designation 32A60-IVBE. Weight is 9.045 pounds.

This wheel is suited for production and toolroom grinding operations in industrial, manufacturing, and maintenance environments. Compatible material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines where a porous, vitrified-bond wheel is specified. The gray, non-tapered, no-recess construction is standard for straight-wheel mounting on conventional wheel flanges.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cut rate and form retention
• 60 grit, I hardness (medium grade) for balanced stock removal and surface finish
• Porous wheel structure promotes coolant flow and reduces heat buildup at the grind zone
• Type 1 straight-wheel geometry with no recess and no taper for standard flange mounting
• Series designation 32A60-IVBE for direct specification matching and replacement ordering
• Rated at 2070 RPM maximum operating speed

Compatibility

Designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines where a 12-inch diameter, 3-inch hole, Type 1 vitrified wheel is specified. Verified 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 machine operator or grinding technician following the machine manufacturer's wheel-mounting procedures and applicable ANSI B11.22 or OSHA 1910.215 requirements. Always power down and lock out the grinder before mounting or removing the wheel. Conduct a ring test before mounting to check for cracks, and never exceed the 2070 RPM maximum speed rating marked on the wheel. Ensure flanges are clean, properly matched in diameter, and that blotters are used between the flanges and wheel faces.
