The CGW 58038 is a 12-inch surface grinding wheel designed for heavy stock removal with a precise finish. It uses PA Pink Aluminum Oxide grain, which is selected for effective cutting of tool steels and hard alloys while helping to manage heat during grinding. This wheel is configured as a Type 5, with a 1-1/2-inch thickness and a 5-inch arbor/shank size, making it compatible with grinders that accept these dimensions. The J hardness classification indicates a balance of hardness and durability for moderate feed rates.
Constructed to provide reliable performance on tool steel and similar materials, this wheel is positioned for applications that demand fast, cool cutting to preserve temper and minimize heat-affected zones. It is described as more durable than WA-grade aluminum oxide wheels under light to moderate feed rates, which can translate into longer service life in appropriate grinding scenarios. The 46-grit PAPink oxide composition supports a practical balance between material removal rate and surface finish, making it suitable for finishing operations where a finer produced surface is important after roughing.
Packaging details indicate the wheel is sold as an individual item, with a package quantity of two per box, which supports stocking and convenience for multi-wheel setups. When selecting this wheel, verify compatibility with your grinding machine’s arbor size (5 inches) and the overall wheel diameter and thickness (12 inches by 1-1/2 inches). Maintain proper grinding practices and dressing routines to keep the wheel performing as intended and to extend its useful life.
