14-piece screwdriver set with individually tested, insulated screwdrivers according to IEC 60900. The individual testing at 10,000 volts ensures safe working at the permissible voltage of 1,000 volts. The Kraftform Plus handle provides comfortable, ergonomic use, preventing blisters and calluses. Hard grip zones allow for high working speeds, while soft zones ensure high torque transfer. The partially laser tip design allows the tip to bite into the head of the screw, preventing slipping. The set includes a voltage tester and two holders for storage. The "Take it easy" tool finder features color coding by profile and size. The anti-roll feature prevents the screwdrivers from rolling away at the workplace.
