The CGW 49545 is a 5 inch diameter zirconia grain grinding wheel designed for high-performance surface metalworking. Built as a Type 27 ( depressed center ) wheel, it is suitable for off-hand grinding and applications requiring comfortable, dust-limited operation with steady material removal. Its 5/32 inch thickness and 7/8 inch arbor create a stable configuration for portable grinders, providing a balance between aggressive material removal and control on diverse metals.
This wheel uses zirconia premium grain, engineered with a bond formulation to promote cooler grinding. That combination helps reduce heat buildup and minimizes distortion or discoloration when working with stainless steel and other tough alloys. The result is a smoother, quieter grinding experience with less operator fatigue, making it a practical choice for repetitive or long-duration tasks. It is framed to resist typical wheel wear while delivering consistent cut across stainless steel, steel, hard face alloys, titanium, inconel, and even aluminum in appropriate contexts.
The wheel is specified with a 36 grit size and a hardness designation of R, suitable for controlled stock removal rather than ultra-fine finishing. With a rated speed around 12,200 RPM, users should adhere to the manufacturer’s guidelines for safe mounting and operation, including inspecting the wheel before mounting and ensuring compatible tooling for the 7/8 inch arbor. The package configuration indicates individual wheels sold with a box count of 25, offering a convenient replenishment option for maintenance or shop environments.
