Efficient nut removal - Enables drills to remove rusted nuts with high torque, allowing repeated use and increasing overall efficiency across varied work conditions. Stable core design - Features a robust composite core structure that resists impacts, maintains operational stability under load, and reduces maintenance needs. Enhanced user comfort - Ergonomic design minimizes hand strain, supports comfortable handling during extended use and repetitive actions, and promotes balanced force application. Modernized site access - Portable and compact with a carrying case, minimizing storage requirements while providing efficient and reliable access to tools at any worksite thanks to an optimized housing structure. Use scenarios - Automotive repair: quickly remove seized rusted nuts on engine or suspension components where high torque is required. - Industrial maintenance: service heavy machinery in workshops or field environments, where reliability and durability matter under demanding conditions. - Construction or DIY projects: on-site tasks with limited space, where compact design and easy transport enable fast tool access and workflow continuity.
