Norton 66253043310 Surface Grinding Wheel 8 in 46 Grit

Product Description

The NORTON 66253043310 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. It measures 8 inches in diameter, 0.25 inches thick, with a 1.25-inch arbor hole. The wheel is constructed with aluminum oxide abrasive bonded in a vitrified matrix, producing a coarse, porous cutting action suited to flat and surface grinding applications. At 46 grit with an I hardness code and medium hardness rating, it delivers aggressive material removal while maintaining consistent wheel breakdown. Licensed grinding professionals and machinist tradespeople install and dress this wheel as part of routine grinding operations.

This wheel fits surface grinders, cylindrical grinders, and CNC cutting tool machines. It is rated for a maximum of 3105 RPM. Compatible material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Series 32A Type 1 specification identifies the exact bond, abrasive, and hardness combination from NORTON for consistent performance across repeat orders.

Key Features

• Aluminum oxide abrasive for broad ferrous and non-ferrous material compatibility
• Vitrified bond provides rigid, porous structure for free cutting action and coolant flow
• 46 grit coarse grade for high stock removal rates
• I hardness code with medium hardness rating balances wheel life and cut rate
• Type 1 flat wheel geometry fits standard surface and cylindrical grinder spindle setups
• Specification code 32A46-IVBE for precise reorder identification

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron per manufacturer specification.

Installation Notes

Grinding wheel mounting and dressing must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation and never exceed the maximum RPM rating stamped on the wheel. Always use the correct flanges, blotters, and arbor hardware for the wheel size and machine type.
