I would like to know why 118 degrees made the standard tip angle for a drill bit.Or for that matter, 135 degrees? 1. Is there anything called standard tip angle? 2. What factors determine the choice of the tip angle? P.S: I posted the same question in Aerospace forum : http://www.eng-tips.com/viewthread.cfm?qid=347077
