The Milwaukee® 3/8 in. 56 piece drive ratchet & socket sets provides better access and maximum strength. The 90-tooth ratchet offers 4 deg of arc swing and a slim profile design, allowing work in tighter spaces. The wrench-compatible socket design has four parallel flats to deter rolling. Optimized socket geometry reduces rounding and stripping. SAE and metric socket sizes are stamped into the flats for improved visibility. The kit comes with a removable inner tray and a portable carrying case. The set comes with accessories included.
