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 15-piece kit comes in a storage tray designed for long-term storage keeping your tool chest organized. Includes 1 each: 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm.
