The MILWAUKEE 9MM Metric Combination Wrench gets 25% more torque than smooth-faced wrenches with its MAXBITE Open-End Grip. In addition to providing increased torque, MAXBITE reduces rounding and stripping of nuts and bolts. This wrench is built from the ground up with an I-Beam handle for optimized comfort and durability. Ink-filled size labels allow for easy size identification and quick distinction between SAE and metric sets. The Milwaukee 9MM Combination Wrench features a Lifetime Guarantee.
