Woodruff key tooling is specialized equipment employed to create woodruff key slots in shafts and other components. Woodruff keys are semicircular keys used to connect machine parts with rotating shafts and spindles. Woodruff key tooling generally comprises a milling cutter and a pilot drill. The milling cutter is utilized to cut the key slot, while the pilot drill creates a hole in the slot's center. This hole aids in aligning the key with the shaft.
