The Wera Kraftform Kompakt 900 19 Piece Hand Impact Driver Set is a professional-grade manual impact screwdriver set designed for loosening stubborn or seized screw connections across a wide range of fastener types. At the core of the set is the 921 Kraftform Plus impact screwdriver, which combines three functions in a single tool: manual impact wrench, compact screwdriver, and pound-thru blade operation. The impact wrench function converts hammer blow impulse into rotary movement, delivering a loosening torque of up to 25 Nm with zero power loss through the pound-thru blade. The impact and screwdriver functions are fully switchable, giving the user flexibility on the job. The set is well suited to automotive, mechanical, and general maintenance work where corroded or over-tightened fixings are a common challenge. The robust bit holder accepts 1/4" hex-drive bits, and the 18 included bits cover the most frequently encountered screw profiles — Phillips, Pozidriv, TORX®, Hex-Plus, and slotted. All bits are specially hardened for use with impact drivers, ensuring durability under repeated hammer loads. A hook and loop fastener strip is included, making it straightforward to keep the set organised in a tool bag or on a workshop wall.
