Hi guys,
Might sounds like a silly question to you guys, but I really don't know :lol:
I need to drill a hole across the end of a bolt, size 5/16 . I use the cobalt bit, which is the best and it will work, according to the sales person at home depot. Well, I sat on it for a while, until my hands are sore and it still doesn't go anywhere.
A friend mentioned that I need a drill-press. To me, the drill press is only helping you to keep the drill bit straight, is that right? Or will it help to press hard on it and it will go through easier?
Thanks.
