CGW 45020 4-1/2" X 3/32" X 7/8" Type 27 36-Grit White Aluminum Oxide Cutting & Notching Wheel

The CGW 45020 is a Type 27 cutting and notching wheel designed for quality performance on standard metalworking tasks. With a 4-1/2 inch diameter and a thickness of 3/32 inch, this wheel is configured for compatible right-angle grinders and is suited for light to moderate metal cutting and notching applications. The wheel features a 7/8 inch arbor and a 36-grit, white aluminum oxide grain, which provides a balance of cut rate and control on ferrous and nonferrous metals. The grade is designated as S (hard), which helps maintain blade integrity and shape during use, particularly under higher RPM operation, up to 13,300 RPM as specified. A notable detail is the presence of contaminant-free formulation, containing approximately 0.1% iron, sulfur, or chlorine, which supports rust-free and corrosion-free results in treated materials. This characteristic can be important when working on parts where surface contamination must be minimized. The grain mixture is described as friable, meaning the abrasive tends to fracture under load to expose fresh sharp edges and potentially improve cutting efficiency as the wheel wears. The combination of wheel geometry, abrasive type, and grain characteristics contributes to a wheel intended for predictable performance in metal fabrication tasks that require both cutting and notching operations.
