CGW 45004 4-1/2" X .045" X 7/8" Type 27 46-Grit Calcium Stearate AO Cutting Wheel for Aluminum

The CGW 45004 is a premium aluminum-cutting grinding wheel designed for efficient, precise work on aluminum and other non-ferrous metals. This 4-1/2 inch diameter wheel uses a .045 inch thickness and a 7/8 inch arbor, making it compatible with common 4-1/2" angle grinders and similar tool setups. Its Type 27 profile and 46 grit finish are chosen to provide steady cuts with minimal burr formation, helping to improve finish quality in sheet and plate work without excessive loading during cutting.

The wheel features calcium stearate AO (aluminum oxide) grain, a formulation aimed at reducing heat buildup and preventing loading when cutting non-ferrous metals. This construction supports clean, consistent removal rates, which is particularly beneficial for fabrication tasks involving aluminum, copper, and bronze. The combination of the grain, grit, and profile is intended to deliver smooth cut lines while maintaining rigidity and stability during operation at typical high RPMs.

In practical use, this wheel is suitable for aluminum, copper, and bronze fabrication, sheet and plate work, and other non-ferrous metal cutting applications. It is packaged as individual wheels with appropriate packaging quantities specified by the supplier for inventory control, and it is intended to be mounted on compatible 7/8" arbor tools running at up to 13,300 RPM. Appropriate safety practices, tool compatibility checks, and wheel inspection prior to use are recommended to maintain performance and minimize the risk of wheel failure.
