Thank you paper, unfortunately I am using a handrill. I do however I am using a vice and the warcomp is pre drilled so im a bit lucky there. Ive done 2 muzzle devices before and never had a problem getting through, but maybe its because they were cheap or had poor heat treatment or nitriding. The hole is 5/64 and i kind of wanted to drill through and then tap and thread it and use a set screw as the pin, but given how hard the metal seems its deterred me. im gonna get 2 carbides tomorrow , ill get a 1/16 and a 5/64th do I need to lube it as i drill?., I thought i was going crazy as the cobalt bits didn’t even make a dent, what do you think of the set screw idea? Anyhow I greatly appreciate your help , Ill let you know how it goes
