best drill bits

[procta]

Depends what you're drilling mate. Most I normally do at work is about 2mm steel doing panel casings. The key is slow RPM, fair bit of pressure on the drill and to try and keep the bit cool, some sort of cutting oil (although I just use WD40 as I hardly put mine through much pressure)

my dad was using engine oil, so wd40 is the best for the job. I will keep that in mind.
