I am planning on making my own turnigs tools (with replaceable bits) and need a few help.
I have a bit that have a 0.172" hole (almost exactly 11/64").
What size tap will be ideal for it?
How do I determine the right drill bit to use for any particular tap size?
I noticed that I can have various no of thread...on hand tapping is more thread better or not? Note that in most cases, I will only have 1/4" deep/thick of threading on what I will make and in my mind I am leaning towards more thread (tpi) right or wrong?
I will be using cold rolled steel and some chrome vanadium steel rod (this may be a bit of a challenge but we will see). Again, I am thinking that it is easier to hand tap with more tpi (because it equates to smaller teeth size)...right or wrong?
Any good source for taps? I've been watching a few at eBay but not sure about the size I will go after yet.
If you know of a good site where I can read about this...I will appreciate it a lot. Any additional info before I venture to this will also be appreciated a lot.
Thank you.
