A bit holder with higher precision and smaller diameter than usual was the goal in the development of the Micro-lock Spin. With its closure and strong magnet, it does not require a large-area steel ball and can therefore pick up drill bits at an ideal angle. A refined aluminium ring with quick release completes the simple design. The functions are housed inside the shaft so that the user can see the screws exactly. A spin function prevents the object from rotating in the hand.
