Abstract
A hob type cutter blade for use in a hobbing process. The cutter blade is formed with at least one cooling passage that permits the flow of coolant through the cutter blade to the contact surface reducing the heat generation as well as dissipating any heat already produced during the hobbing operation. During manufacturing, the cooling passage is sintered into the carbide cutter blade without the addition of separate operation.
