The main difference (for this purpose) between the HSS drill and cobalt
steel is the split point geometry of the cobalt drill. A split point drill
is self centering which is especially helpful when using a hand drill as
opposed to a drill press.

<paul.mcallister@qia.net>
Hi all,
I have to drill the tail wheel spring and I must admit to not looking
forward to doing this with a hand drill. I am assuming that the spring
steel will be pretty tough going.
I was thinking of buying a cobalt drill for the purpose, but I am wondering
what others have done. Any advice would be appreciated.
Paul
