The wera kraftform plus chiseldriver in the 1.2Mm blade thickness 138mm blade length configuration is the largest in the range, designed for heavy-duty slotted screw work where maximum reach and increased torque capacity are required. With its longer blade and greater blade width, this variant excels when driving larger slotted fasteners or tackling seized screws that demand more leverage. The multi-component kraftform handle is engineered for fast, ergonomic, low-fatigue use, combining smooth hard zones for rapid rotation with soft grip zones that optimise torque transfer. The hexagonal blade extends through the entire handle to ensure no energy is lost when struck with a hammer. Ductile tempered steel construction prevents splintering under impact, and the wera black point tip produced through a complex hardening process offers an exact fit and outstanding corrosion resistance. The impact cap with integrated square take-up enables use with t-handles, zyklop ratchets, and mini ratchets, while the hexagonal bolster accepts spanners for extra torque output. The anti-roll hex profile ensures the tool stays put on the bench.
