BigJoe365 Posted November 4, 2020 Share Posted November 4, 2020 I am installing a TTI bolt release and find myself without the required tools. …I have 4-40 tap, need 5-40 tap. same scenario with the drill bit. however I did start with a small pilot hole first. I ordered the tap and drill bit on amazon as nobody local had it on the shelf. I have a ton of tap & die and 2 tons of drill bits...none the right ones.. If I am to invest into more of both, what do you Gunsmiths recommend. primarily the drill bits. before ya say it, Yes I know about the no drilling bolt release assembly. I just like to be difficult LOL. Hey thank you for any input. Quote Link to comment Share on other sites More sharing options...
Doge Posted November 4, 2020 Share Posted November 4, 2020 Order them on job basis. Your best option for individual items through a reliable supplier is McMaster-Carr. If I am trying to put a hole or threads into something hard to replace, I am using good tools. Quote Link to comment Share on other sites More sharing options...
