Norton 66252941948 Surface Grinding Wheel 80 Grit 7 in

Product Description

The NORTON 66252941948 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous metals. Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and maintains its form through extended grinding cycles. At 80 grit with a K hardness code (medium grade), it balances aggressive material removal with controlled surface finish. Rated to 3600 RPM, it is sized at 7 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. Machinists, tool-and-die technicians, and surface grinder operators are the primary installers and users of this product.

This wheel is suited for surface grinding, cylindrical grinding, and use on CNC cutting tool machines. It performs across a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The non-porous, non-tapered Type 1 flat wheel profile makes it a straightforward fit for standard horizontal and vertical spindle surface grinders in both production shop and toolroom environments.

Key Features

• Aluminum oxide abrasive grain for consistent performance on steels, cast iron, and aluminum
• Vitrified bond construction maintains wheel shape and provides free-cutting action
• 80 grit, medium grade (K hardness) balances stock removal rate with surface finish quality
• 3600 RPM maximum speed rating for safe operation on standard surface grinders
• Type 1 flat wheel, non-porous, non-tapered, no recess — straightforward mounting with standard flanges
• Series designation 32A80-KVBE confirms OEM-level specification compliance

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Confirmed 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 and wheel changes should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 and OSHA 29 CFR 1910.215 guarding requirements. Always 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 mounting, and never exceed the stated maximum RPM of 3600. Confirm the arbor hole fits the machine spindle correctly and that proper flanges and blotters are used before returning the machine to service.
