The Wera Kraftform Kompakt 100 is a general purpose set for use with a variety of fasteners and includes hex keys in addition to screwdriver bits and bit holding screwdriver. The bit holding screwdriver with Rapidaptor allows for rapid one-handed bit change and self-lock, with a quick release chuck for use with 1/4 hex bits. A free turning sleeve makes it easy to postion the attached bit into the screw and avoid slipping which can damage the workpiece. The screwdriver features a Wera Kraftform handle, ergonomically designed to fit comfortably in the hand with special hard and soft zones to provide better turning power with less effort and making repeated turning easier. Together with an assortment of 25mm and 50mm long screwdriver insert bits the set includes 8 L-Keys. Most of these (excluding the 1. 5mm size) have a Hex-Plus profile to reduce the notching effect that can damage the screw head.
