High-quality bit holder with ratchet function. The fine-toothed ratchet integrated in the handle ensures fast employees. The innovative ratchet mechanism enables "whirling" when the screw offers little resistance. Switching the screwing direction is intuitive: If the ring switch is turned to the right, the screw is screwed to the right; if the ring switch is turned to the left, the screw is screwed to the left. For precise employees, the ratchet mechanism can be deactivated with the 0 position. The Rapidaptor quick-change chuck enables lightning-fast bit changes without an auxiliary tool. The strong permanent magnet holds the bits firmly in place. The ergonomically designed Kraftform handle prevents blisters and calluses. The grip zones made of hard material ensure fast gripping without "sticking" and therefore high working speed, while the grip zones made of softer material ensure excellent grip and high torque transmission.
