How to drill / prep bolts for lockwiring / race prep?

Can you use a simple hand-held drill for creating the holes in bolts for lock-wiring / race prepping or should I go to a professional with all my bolts and get them to use the drill press? Like, how do you do it at home?​What's the best way to lockwire you entire bike without having to spend hundreds on a drill press?​​ via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/9n1doa/how_to_drill_prep_bolts_for_lockwiring_race_prep/?utm_source=ifttt
