Product Knowledge

1. Tap wrenches provide leverage to operate the wrench with both hands to process, repair and clean the internal threads. They can be divided into ordinary adjusting tap wrenches, ratchet tap wrenches or T-handle tap wrenches.
2. When tapping, every time the wrench rotates 1/2 turn, it should be reversed about 1/2 turn, so that the chips will be broken and discharged.
3. If it is difficult to rotate when tapping, do not increase the rotation force. Need to withdraw the tap frequently to remove the chips in the hole.

Applications

• The tap wrench is specially designed for use with taps, reamers, drills, screw extractors and other small hand-turned tools.
• It is very convenient for hand operation and can improve work efficiency. It is good for DIY tapping.
• Taps of any size can be clamped within the clamping range. Widely used in industry (mold), and home (furniture, home appliance).

Important Tips

1. At the beginning of tapping, try to position the tap as much as possible , then apply pressure to the tap and turn the tap wrench. When tapping 1-2 turns, carefully check and correct the position of the tap. Generally, the tap position should be correct when tapping 3-4 turns of thread. Then only need to rotate the wrench, and no more pressure on the tap, otherwise the thread profile will be damaged.
2. When tapping the screw holes of plastic materials, add lubricating coolant. For steel materials, engine oil or emulsion with higher concentration is generally used. If there is higher demand, rapeseed oil or molybdenum disulfide can be used. For stainless steel, 30# engine oil or sulfurized oil can be used.
