The Wiha 77891 11-in-1 Multi-Driver brings exceptional multi-tool adaptability, maximum workspace efficiency, and physician-endorsed handle ergonomics straight to your active trade setup or tool pouch. Purpose-built to eliminate the heavy weight of carrying a dozens of separate hand drivers, the constant clutter of loose interchangeable tips inside a tool tray, and the painful blisters caused by hard plastic handle designs, this premium professional multi-bit driver sets an absolute mechanical standard. It arms industrial maintenance mechanics, commercial HVAC technicians, residential electricians, and trade fabricators with a high-performance multi-tool optimized to swap bits instantly, adjust equipment assemblies, turn hex head panels, and handle diverse fastening tasks cleanly.
Outstanding physical force transmission and premium USA-manufactured durability form the core baseline architecture of this versatile multi-driver. Forged inside a direct-molded dual-durometer SoftFinish® handle frame, the 8-edged large-diameter cushion grip puts maximum surface area into the palm of your hand for efficient torque transmission with significantly less fatigue. The interior housing integrates a heavy-duty mechanical core with an interchangeable shaft that holds 8 essential premium tool steel screwdriver bits finished in zinc phosphate alongside 3 built-in chrome-plated nut drivers (1/4", 5/16", and 3/8"). To prevent accidental workplace damage, the driver features precision-machined, exact-fit tips to eliminate destructive cam-out, while integrated anti-roll parallel flats along the handle stop the tool from sliding off slanted work tables.
