The MILWAUKEE 15pc Metric Ratcheting Combination Wrench Set provides better access and the longest life. It features 2.5° of arc swing with 144 ratcheting positions for better access in tight spaces. The durable double-stacked pawls in the ratcheting mechanism offer the longest ratchet life and improved access with 144 ratcheting positions. The MAX BITE Open-End Grip improves the wrench's grip on nuts and bolts, delivering up to 25% more torque, and the geometry reduces rounding and stripping. The I-Beam handle design provides comfort in high-torque applications and features easy-to-read ink-filled size labeling.
