Hi Ken:
I hate it when that happens...I find that deeper holes in aluminum
need to be cleaned out more so they won't bind 'cause it's gummy
stuff. Try putting the workpiece in a vise and tapping the bit with
a hammer and small drift. Sometimes just working it in different
directions will loosen it off.

Hi,
This might sound a bit basic but it has stumped me! While drilling
on
my lathe, I have broken two 2mm drills in two separate holes in a
steam engine alluminium casting. They have both broken off flush so
there is nothing to get hold of and there is not a lot of space
around them. I have thought of over-drilling the whole lot out (if
I
can) and making a screw-in plug and milling it flush.
Is the casting a write-off - Or is there another way?
All help appreciated
Regards
Ken
