It's really easy man... you can do EEEEETTTTTT.
Seriously, unless you're a newb and your fellow club members are having you drill a tempered tank, without warning you, (wonder who this happened to???) it's easy.
Just take your time, use plenty of water, and let 'er rip.
Years ago I had SonX and DaughterX help me drill a couple different tanks. They've even done it here and at a club meeting or two.
