[QUOTE=1. Get two or three drillbits because they will go dull.=QUOTE]


I'm not sure this should be happening if your just making a set, a drill bit designed for steel should last a bit longer than this.

But a newbie mistake would be to not use lube, ie wd40 or even old engine oil, when drilling, it keeps the drill bit cooler and stops it from losing its temper which would result in premature bluntness. Try and keep the bit well lubed when drilling and you will only need one drill bit.

Awesome thread, I am making a pair for definite now.
