How do you know what size hole to drill for the thread?
For metric threads, the point can usually be calculated by subtracting the pitch from the diameter of the thread. for example for M5x0. Tap 75 equals 50.75mm = 4.25mm. For inch (inch) threads, the tap size is calculated the same way: diameter minus pitch.
How to know the size of the drill for tapped holes?

What size hole do you need to drill to cut a 1/4 20 threaded hole?
If the hole is too small, it will be difficult to tighten the screw. This could damage the bolt threads. Too large a hole will result in a loose bolt that will not retain 100% of its structural strength when fully tightened. For a 1/420 screw, the optimal bit size is No. 7 or 13/64.

How big is the faucet hole?
Standard taps and spouts generally require an opening with a diameter of at least 22mm. Solid cast iron mixers, under which hot and cold water is supplied, usually require holes with a minimum diameter of 32 mm.
What size drill should I use to cut a 3/8 hole?
The best way to tell the thread size of your faucet or faucet is to remove the aerator (the part that unscrews from the end of the faucet) and measure the diameter (center) of the thread.
What size hole do you make for a 1/420 tap?
For metric threads, the point can usually be calculated by subtracting the pitch from the diameter of the thread. for example for M5x0. Tap 75 equals 50.75mm = 4.25mm. For inch (inch) threads, the tap size is calculated the same way: diameter minus pitch.
What size do I need for a 20 quart drill?
For metric threads, the point can usually be calculated by subtracting the pitch from the diameter of the thread. for example for M5x0. Tap 75 equals 50.75mm = 4.25mm. For inch (inch) threads, the tap size is calculated the same way: diameter minus pitch.
