Norton 66253262697 Surface Grinding Wheel 80 Grit 12in

Product Description

The NORTON 66253262697 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous materials. Built with aluminum oxide abrasive bonded in a vitrified matrix, this wheel delivers consistent cutting action and thermal stability across extended grinding cycles. At 12 inches in diameter, 1 inch thick, and with a 5-inch arbor hole, it mounts to full-size surface and cylindrical grinders. The 80-grit, K-hardness (medium grade) specification suits applications requiring a balance between material removal rate and surface finish quality. Rated to 2070 RPM, this wheel carries the 32A80-KVBE specification designation and weighs 7.97 pounds.

This wheel is suited for production and maintenance grinding on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. It is a practical choice for tool and die shops, machine shops, and industrial maintenance operations requiring a reliable large-diameter wheel for flat or peripheral grinding work.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cut rate and thermal resistance
• 80 grit, K hardness (medium grade) balances stock removal with achievable surface finish
• Type 1 flat wheel profile with no recess and standard 5-inch arbor hole
• Rated to 2070 RPM for use on standard surface and cylindrical grinder spindles
• Porous wheel structure promotes coolant flow and chip clearance during wet or dry grinding
• 32A series designation confirms Norton premium aluminum oxide grain formulation

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.

Installation Notes

Grinding wheel installation should be performed by a qualified operator following ANSI B11.9 and OSHA 1910.215 safety standards. Always perform a ring test before mounting and confirm the spindle RPM does not exceed the 2070 RPM wheel rating. Power down and lock out the grinder before mounting or removing the wheel. Never exceed the rated speed, and ensure flanges and blotters are clean and properly sized for a 12-inch wheel.
