Too right!

As for myself, I always drill with a drill press stand, an 18 watt
mini-fluoro bulb close-up, and a 4x head magnifier. Pretty hard to
confuse the drill bit with the copper in ∗that∗ environment :P

Can't wait, though, for my mech eng to get back from his motorbike
touring and build the transport for my CNC tool. The CNC controller
won't give a damn what kind of light is present :)
