Wera Chiseldriver for fastening, chiselling, and loosening seized screws. Single-component Kraftform handle for fast and low-fatigue working. A hexagon blade made from high-quality bit material extends right through the blade, ensuring full transfer of force, even when struck with a hammer. The ductile tempered material prevents the blade from splintering or breaking. It comes with an impact cap for durability and reduced risk of splintering. More torque can be transferred with the help of an open-end or ring spanner applied to the integrated hexagonal bolster. The Wera Black Point tip and a complex hardening process ensure a long service life of the tip, enhanced corrosion protection, and an exact fit. The hexagonal anti-roll feature prevents any bothersome rolling away at the workplace.
