About Dies

Made of alloy tool steel, hardness and wear resistance. Used to repair external threads. When in use, the conical locking hole of the die is aligned with the screw of the wrench and tightened. The conical keyhole has a strong locking force and is not easy to loosen.

Suggest:

Appropriate lubricating oil should be added to the die-cutting edge when cutting, It is to be reversed every 1/4~1/2 turn to facilitate chip discharge from the chip hole.

Tips

  • Please be sure to take protective measures when working, you need to wear goggles and protective gloves.
  • Before tapping confirm whether the diameter of the round hole is appropriate. Be sure to select the appropriate cutting oil for the complex tapping process and apply anti-rust oil for maintenance after use.
  • When tapping, control the speed according to the hardness of the material, it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss.

I had a 7/8-14 tpi hole to tap and this was purchased at the right price. Worked great. If you have a lot of holes such as in production machining you may want to check it other taps.
