Interchangeable screwdriver set with 10 x tough viscous screwdriver blades. Kraftform bit-holding handle designed to fit perfectly into the hand to allow for fast, comfortable and ergonomic screwdriving. Handle hard zones glide like wheels across the hand for high working speeds, while soft zones provide grip to ensure high torque transfer and comfort during intensive use. Rapidaptor technology allows for rapid bit change without any extra tools and also only requires one-handed use. Rapid-in allows the bit to be inserted without moving the sleeve due to a self-lock mechanism. Rapid-out allows for the bit to be changed by simply pushing the sleeve forward, this works via a spring mechanism lifting the bit off the magnet. Rapid-spin, a free-turning sleeve, allows screw steadying at the start of the screwdriving process. Supplied in a compact pouch.
