CGW 45221 5" X .094" X 5/8"-11 Type 27 36-Grit Aluminum Oxide 3-IN-1 Cut/Grind/Finish Wheel

The CGW 45221 is a 5-inch diameter aluminum oxide grinding wheel designed for three-in-one performance: cutting, grinding, and finishing in a single wheel. With a 5/8-11 mounting arbor and a thickness of 3/32 inch, this Type 27 wheel is optimized for low-profile contact and efficient operation on suitable materials. The grain is aluminum oxide, chosen for its balance of cutting action and surface finishing potential, while the wheel’s S hardness indicates a relatively rigid structure for consistent performance under higher RPMs.

A key feature is its contaminant-free composition, specified to contain about 0.1% iron, sulfur, or chlorine, which helps minimize rust and corrosion in metalworking environments. The wheel is reinforced with three layers of fiberglass net, contributing to added strength and flexibility to resist wheel breakage during grinding and to maintain shape under load. This design supports quicker material removal without frequent wheel changes, potentially improving production efficiency in maintenance, repair, and operations workflows.

Typical use scenarios include cutting and grinding tasks on metal surfaces where a Type 27 wheel provides a flatter grinding face for lower-angle contact, along with a finish step that reduces the need for secondary tooling. When selecting this wheel, ensure compatibility with 5/8-11 hubs and confirm that the workpiece material and grinding operation align with 36-grit aluminum oxide performance. The package is sold as individual wheels, with box quantities listed as 10, which is helpful for stocking and consistent supply in maintenance shops.
