The Wera 8004 C Zyklop Metal Ratchet With Switch Lever has 1/2" drive & is forged from chrome-molybdenum, making it extremely robust & tough. The slim design means that you can work in very confined spaces while the fine-tooth mechanism (with 72 teeth) provides a return angle of only 5°. There is a switch lever for convenient change of direction as well as a secure locking function.
