Tapping Steel

I do not think that I have ever tapped steel before, but I am pleased to report that with oil on the tap, cold rolled isn't much worse than aluminum.  Even with the Tapmatic I wasn't terribly concerned about breaking a tap.  I really need a bottoming tap, which arrived today.

And the bottoming tap was spiral flute.  It did a lovely job tapping a 1/2"  hole (which is 10 revolutions).
