The 28-Piece Metric ½¿ Drive Ratchet & Socket Set is designed from the ground up to offer you better access in tight spaces and maximum tool strength. The 90-tooth ratchet tool offers 4° of arc swing and a slim profile design, allowing you to work in tighter spaces. The MILWAUKEE sockets feature FOUR FLAT sides, which deter rolling and are wrench-ready for enhanced versatility. Our optimized socket geometry helps reduce bolt rounding and stripping. The ½¿ sockets have their metric measurements laser engraved into the flats for improved, easy-to-read visibility. The ½¿ ratchet and socket kit comes with a removable inner tray, designed to be stored long-term in a steel storage chest. The set also comes with a durable carrying case for ultimate portability and accessories so you can get every job done, both in the garage and on the jobsite. Our drive ratchet and socket set is backed by a lifetime guarantee.
