Milwaukee’s Ratchet & Socket Sets are designed from the ground up to offer users Better Access and Maximum Strength. The 90-tooth ratchet offers 4° of arc swing and a slim profile design, allowing users to work in tighter spaces. Our innovative socket design has four parallel flats, which deter rolling and are wrench-compatible. The optimized socket geometry helps reduce rounding and stripping. Socket sizes are stamped into the flats for improved visibility. The kit comes with a removable inner tray, perfectly designed to be stored long-term in a steel storage chest, and comes in a carrying case for ultimate portability. The set comes with accessories included so that our users can get every job done, both in the garage and on the site. 4° of Arc Swing. Socket Flats Deter Rolling. Removable Inner Storage Tray.
