Wera Chiseldriver for fastening, chiseling, and loosening stuck screws. One-component Kraftform handle for quick and fatigue-free working. A hexagonal blade made from high-quality bit material extends through the blade, ensuring complete power transmission even during hammer strikes. The ductile tempered material prevents the blade from chipping or breaking. Equipped with a striking cap, it ensures durability and reduces the risk of chipping. More torque can be applied with an open or ring wrench placed on the integrated hexagonal drive. The Wera Black Point tip and a complex hardening process ensure a long lifespan of the tip, improved corrosion protection, and a precise fit. The hexagonal anti-roll feature prevents annoying rolling away at the workplace.
