If your toolkit gets too heavy because of the number of screwdrivers you’re carrying, you may want to consider changing to a system where you simply insert a bit into a handheld bit holder with quick-release chuck. WERA offers several high-quality bit holders, one with a ratchet.
The sets all sport the proven WERA Kraftform handle, where your whole hand gets to grips with the handle. The smooth, hard zones (black) turn smoothly through your hand when regripping to enable unusually high working speeds. The grippy, soft zones (green) provide optimal contact areas for the hand to generate high turning moments.
The Rapidaptor quick-release chuck with rapid-in, rapid-out, rapid-spin, chuck-all und single-hand function plus magnet supports bit swapping at lightning speed.
