I slap in a 6.5mm drill - it bends about like a bendy thing in Bendy Convention.

Are your drills sharp? Is the lathe turning in the correct direction?:rofl:
Is the tail-stock aligned correctly?

Drilling a hole in aluminium should not cause you any problem. Similarly, if your boring tool is sharp, it should easily cut a clean hole.

What depth of cut are you trying?
