Hard handle zones allow for high working speeds, while soft handle zones ensure high torque transfer. The combination profile of slotted and Pozidriv is specifically designed for use on terminal blocks, fuse boxes, switches, and relays. Individually tested at 10,000 V for safe operation at the rated voltage of 1,000 V. The hexagonal anti-roll feature prevents bits from rolling away at the workplace.
