With the Metabo Futuro keyless drill chuck, you change bits from 1 to 13 mm quickly and entirely by hand without needing a separate chuck key. You avoid downtime and keep your projects moving without interruption. The chuck automatically retightens as drilling resistance increases, ensuring cylindrical bits stay securely gripped under heavy loads. Even after demanding tasks, you can release the mechanism smoothly by hand. Built with an 89 mm length and a 1/2"-20 unf female thread, it mounts easily on clockwise hand-held drills or stationary drill presses for dependable performance.
