Norton 66253364508 Surface Grinding Wheel 14x2x5 46 Grit

Product Description

The NORTON 66253364508 is a Type 1 straight surface grinding wheel designed for aggressive stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability under sustained wet grinding conditions. At 46 grit with a J hardness (coarse grade), it is suited for applications where fast material removal outweighs fine surface finish requirements. Rated at a maximum of 1800 RPM, it is intended for use on industrial surface grinders and CNC cutting tool machines. Licensed HVAC, plumbing, and industrial trade professionals specify this wheel for toolroom and maintenance grinding operations.

This wheel fits surface grinder and cylindrical grinder setups commonly found in machine shops, maintenance facilities, and toolrooms. It is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 5 inch arbor hole accommodates standard industrial spindle configurations. The porous, vitrified structure promotes coolant flow during wet grinding, helping to manage heat at the workpiece.

Key Features

• Aluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, and cast iron
• Vitrified bond provides rigidity and open structure for efficient wet grinding
• 46 grit coarse grade for high material removal rates
• J hardness (medium hardness rating) balances wheel life against cutting aggressiveness
• Porous wheel structure supports coolant penetration and heat dissipation
• Type 1 straight wheel geometry with no recess, compatible with standard surface grinder flanges

Compatibility

Rated for use with CNC cutting tool machines, cylindrical grinders, and surface grinders. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Series designation: 32A Type 1, specification 32A46-JVBE.

Installation Notes

Grinding wheel mounting must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; never mount a damaged wheel. Confirm that the machine spindle speed does not exceed the 1800 RPM maximum rating marked on this wheel.
