Hand relief design provides ergonomic fatigue reduction for repetitive motions, enabling comfortable work with less hand strain over long tasks. Reinforced core with composite materials keeps the tool stable under high load, reduces maintenance, and delivers impact resistant reliability for durable performance. Powerful torque converts a screwdriver into a high torque nut remover, delivering strong turning force for rusted components while maintaining consistent performance and productivity. Space saving and portable: integrated carrying case for easy transport and storage. Slim housing design saves space and enables quick access to tools on the job site for maximum convenience. Use scenarios Automotive and equipment maintenance: loosen rusted nuts and seized bolts with reliable torque, reducing the need for additional tools and effort. Construction site and field work: perform repetitive fastening tasks with less fatigue, especially in tight spaces where tool access is limited. Industrial service and repairs: quickly switch between driving screws and removing stuck fasteners on machinery, maintaining steady performance in demanding conditions.
