Milwaukee has designed the combination wrenches from the ground up， delivering maximum torque and ultimate user comfort. The MAX BITE open-end grip improves the wrench's grip on nuts and bolts， and the geometry reduces rounding and stripping. The comfortable I-Beam handle design allows superior user comfort even while applying high torque. Milwaukee wrenches feature ink-filled size labels for easy size identification and quick distinction between SAE and metric sets. The 7-piece kit comes in a portable locking storage tray offering organization both on and off the jobsite. Includes one each: 8 mm， 10 mm， 12 mm， 13 mm， 14 mm， 15 mm， 17 mm.
