Norton 66253044064 Surface Grinding Wheel 80 Grit 8in

Product Description

The NORTON 66253044064 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous materials. Measuring 8 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole, this wheel carries an 80 grit, K hardness (medium grade) specification and is rated to 3600 RPM. The vitrified bond promotes cool, free-cutting action and consistent wheel breakdown, making it a reliable choice for surface grinder work where dimensional accuracy and finish quality matter. It weighs 3.14 pounds and carries the 32A80-KVBE specification designation.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. Stated material applications include 400 Series Stainless, Hard Carbon Steels, Soft Carbon Steels, Tool Steels, Aluminum, Cast Iron, Ductile Iron, and Gray Iron. The medium grade and 80 grit combination makes it appropriate for general-purpose surface grinding where a balance between material removal rate and surface finish is required. It is sold individually.

Installation Notes

Grinding wheel mounting and dressing should be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum rated speed stamped on the wheel.
