Wera Chiseldriver for fastening, chiseling, and loosening rusted screws. It features a one-piece Kraftform handle for quick and fatigue-free work. A hexagonal blade made of high-quality bit material extends through the blade, ensuring complete power transmission even with hammer strikes. The ductile tempered material prevents the blade from chipping or breaking. It comes with a striking cap for durability and a reduced risk of chipping. With the help of a ring spanner or open-end wrench applied to the integrated hexagonal socket, more torque can be transmitted. The Wera Black Point tip and a complex hardening process ensure a long service life, improved corrosion protection, and a precise fit. The hexagonal anti-slip feature prevents annoying rolling on the work surface.
