【Super Set】- This product includes three different bit specifications, six characters, cross and mark, totaling 12 pieces, plus a 1/2 inch detachable handle, which will largely meet your usage needs. 【High Quality Material】- The entire punch set is made of vanadium steel, offering high hardness, wear resistance, and rust resistance. You don't need to worry about the product deforming easily or rust affecting its performance. 【Adjustable】- The head can be adjusted by rotating it back and forth, allowing screws to be tightened or loosened. Pointing to “L” loosens the screw, and pointing to “R” tightens the screw. 【Wide Usage】- This punch set is mainly used for disassembling stubborn bolts, auto parts, and rusted bolts that are extremely difficult to remove. The set comes with an iron storage box for convenient carrying and practical use. 【Tips】- Align the drill with the screw and strike the back of the hammer drill directly with a hammer. The front drill rotates automatically, and the head can be adjusted to rotate forwards and backwards. The upper and lower screws can be adjusted. 1/2" Screwdriver Set Slot: 8x36mmx4; 8x70mm Philips: 8x36mmx4; 8x70mm Hex: 6x36mm; 8x36mm Scope of delivery: 1 set Note: The data is based on manual measurement; please allow a 1-42 cm error.
