Milwaukee's 12 pc. 3/8 in. drive ratchet set delivers ultimate versatility and access. The slim-profile ratchet features a pivoting head that can be used as a ratchet, a nut driver, or any angle in between. Milwaukee's proprietary sockets feature a parallel flat design for wrench compatibility and to deter rolling. Socket sizes are stamped into the flats for improved visibility. The kit is stored in a soft-sided carrying case that includes a socket rail to keep sockets and accessories organized, both on and off the jobsite.
