Wera Koloss is the world's first ratchet that can safely be used as a hammer
The Koloss ratchet combines a reversible, heavy‑duty design with a square drive that can safely be used as a hammer. A double‑pawl mechanism and a very small 6° return angle let you tighten and loosen screws quickly, even in cramped spaces, while the drop‑forged hammer head and hardened square drive prevent damage from impact.
The tool is supplied with a multi‑component Kraftform handle, optional extensions, centring pins and protective pads. It is intended for a wide range of industrial applications such as mechanical engineering, aircraft construction, mining, petroleum, scaffolding and railway vehicle construction.
