Tips

  1. Before tapping confirm whether the diameter of the round hole is appropriate, and to take protective measures when working.
  2. When tapping, it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss. If it encounters difficulty in rotation, the tapping should be suspended.
  3. Be sure to select the appropriate cutting oil for the complex tapping process and apply anti-rust oil for maintenance after use.

I needed the die, I had a tap already. I will grind it to a bottom tap. I use it to modify cases

the size I needed is not included in many sets with multiple taps and dies. Local hardware and even big box stores don't stock it. Had to go online. several choices and this one tap came with an included die. HSS too.
