Advantages: T-type winch can adjust angle and direction, perfect for all kinds of scenes. The rubber part can strengthen the stability of the winch, ensure that the process of use does not slip, and promote perfect process results. The T-shaped tap wrench design also allows one-handed operation, more convenient to use. Material and durability: This set is made of bearing steel, steel 45 high-speed steel and other high-precision alloy steel materials. Strong toughness is not easy to break, smooth cutting mouth can reduce friction and heat, extend the service life. Method of use: put the square handle of the faucet into the stringer and tighten the stringer.The drill can be perfectly matched with the winch. At the same time, you can also equip it with drills and other machines. However, be careful not to use it for materials that are too hard, which may damage the bit. Application: The set can be used to cut continuous curved materials, suitable for production and One-piece, small-batch repair can be used in aluminum alloy, copper, spring steel, cast iron, galvanized pipe and hard plastic wood, etc. not suitable for stainless steel and other high hardness materials. Note: When tapping, the centerline of the tap should be consistent with the centerline of the drill hole. No additional pressure is needed after supplying the faucet. Each time the tap and die are rotated, they should be reversed about 45 to cut the chips, to avoid jamming. If the tap is hard to turn, do not increase the turning force so as not to break the tap.
