Precision, packed to go.When your everyday carry needs a tune-up, the ToGo Driver is built to keep you moving. Designed in collaboration with custom maker Joe Wu, this compact maintenance tool puts professional-level functionality right in your pocket. The textured anodized aluminum handle unscrews into two pieces, revealing an internal compartment that securely holds seven precision Wiha 4mm micro bits and a 1/4" to 4mm bit adapter - so the tool you need is always on hand. A ball-bearing spinner ensures smooth, controlled turns for quick takedowns or reassembly, while a magnetic driver tip keeps bits locked in place until the job is done. Includes T6, T8, T10, T15, T20 Torx bits, 3.5mm slot head and Philips head bits, and 1/4" to 4mm bit adapter. Overall length 3.48".
