Milwaukee has designed our 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. MAX BITE offers 25% more torque than competitive wrench designs. 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 pc. kits come in a storage tray designed for long-term storage, keeping your tool chest organized. Standing behind our products, Milwaukee offers a lifetime guarantee on all of our combination wrench sets.
