The wera kraftform kompakt 400 ra rapidaptor is a professional ratchet screwdriver set designed for tradespeople requiring precision, speed and versatility across a wide range of fastening applications. This 17 piece imperial set combines wera's renowned ergonomic design with advanced rapidaptor technology, delivering exceptional performance for electricians, carpenters, engineers and maintenance professionals working with both metric and imperial fasteners. The 416 ra t handle screwdriver features an integrated 80 tooth ratchet mechanism with a minimal 4.5° return angle, allowing rapid screwdriving in confined spaces without repositioning the tool. The ratchet mechanism is completely embedded within the handle for comfortable operation, whilst the reversing lever enables quick one handed direction changes. The rapidaptor quick release chuck accepts all standard ¼ hexagon drive bits conforming to din iso 1173 c 6.3 and e 6.3, with a fast rotating sleeve that enables lightning fast bit changes and maintains high working speeds. Wera's kraftform handle design ensures optimal force transmission and reduced fatigue during extended use. The ergonomic profile fills the palm whilst fingers sit securely in softly rounded recessed grips, maximising contact area and minimising friction loss between hand and handle. This comprehensive set includes 16 tough 89mm bits covering the most commonly used drive types phillips, torx, imperial slotted, square plus and a metric slotted bit, making it ideal for hvac installation, electrical enclosure work, machinery maintenance and general trade applications. The robust textile storage box keeps the complete set organised and protected on site.
