The Milwaukee Tool 7-pc and 15-pc Ratcheting Combination Wrench Sets offer a 2.5 degree arc swing, 144 ratcheting positions, an anti-slip open-ended grip and an I-Beam handle design. Size labels on each of the wrenches are ink-filled for easy identification and readability from multiple angles. These labels use different colors to differentiate SAE and metric sets (red for SAE and black for metric). The 7-pc set comes in a portable, locking storage tray for organization on and off the jobsite, and the 15-pc set comes in a storage tray designed for long-term storage.
