drill bit size

[Jim Martin]

I am working on a project and can not find my drill tap chart
I look on line but they just give it to me in bit #'s not size

So can some one tell me what size bit I need for a 7/8 - 16 tap

thanks

7/8 - 14 tap? Is probably what you mean..



51/64 drill bit for 75% thread.



7/8 - 9 would be.... 49/64 drill bit.

 

[Jim Martin]

it says in 7/8 -16 right on the tap itself.............

13/16"

 

[Jim Martin]

thank you

Why trust a machinist that gave up the trade to become a carpet cleaner?
