Staggered-tooth cutters

A staggered-tooth side-and-face cutter, also having teeth on the periphery and on both sides, is designed for deep-slotting operations. In order to reduce chatter and provide maximum chip clearance, the teeth are alternately right-hand and left-hand helix, and each alternate side tooth is removed. Fig. 11.8(d). Staggered-tooth cutters are available in the same sizes as the plain side-and-face type.
