Super Set - This product includes three different bit specifications, six characters, cross, and mark, totaling 12 pieces, along with a 1/2 inch detachable handle, designed to meet a wide range of usage needs. High Quality Material - The punch set is constructed from vanadium steel, offering high hardness, wear resistance, and rust resistance. The durable build ensures the product resists deformation and rust, maintaining long-term performance. Adjustable - The head can be adjusted by rotating forward and backward, allowing screws to be tightened or loosened. Position L releases the screw, while position R tightens it. Wide Usage - This punch set is ideal for disassembling stubborn bolts, automotive parts, and rusted fasteners that are difficult to remove. The set comes with a sturdy iron storage box for easy transport and organized storage. Tips - Align the bit with the screw and strike the back of the handle directly with a hammer. The impact drives the front bit to rotate automatically, and the head can be adjusted for forward or reverse rotation. The upper and lower components allow adjustment for optimal operation.
