How do you calculate tap drill size?
Tap Drill Size Formula
- First, you need to measure the overall diameter of the tap. It will require a micrometer. ...
- The next step is to use the formula Dh = Dbm — 0.0130 (percentage of the full thread desired/ Ni) to find the correct drill bit size.
- Now apply for the numbers in the formula with 84 percent. ...
- This is the final step. ...
What size drill bit for m8x1.25 tap?
To figure out the tap size for any metric tap, all you do is subtract the pitch from the size of the tap and that is your drill size. So for, M8x1.25 1.25mm - 8mm = 6.75mm So, 6.75mm is the drill size. To convert that to inches, 6.75/25.4= .265 .265 is 17/64ths Confused yet? :smile:
