The Wera 900 series, the chisel-driver, is a rugged tool designed for tough jobs in the workshop and in industry. It can be used to loosen seized screws and hose clamps, as well as to create holes in the wall. The tool features a pound-thru hexagonal blade made from hardened material, preventing splintering and reducing the risk of injuries. The hex bolster allows for higher torque transfer using an open-jawed or ring spanner. The Kraftform® handle provides a comfortable grip and enables faster, more powerful, and less tiring screw-driving action.
