Fast spiral tap speeds

[Foster]

I've used the hand taps for years: lots of oil, take your time, put oil in the hole as you cut the threads, back the tap out to clear the tool after a few turns, remember to use oil, don't force the tap it will cut the threads and of course, oil is your friend.

Very successful on all the taps I've done. And with all the roboteers I've taught to tap holes.

I need to tap four 5/16" holes in 2" steel pipe (clearly not a robot project) and a friend gave me "fast spiral tap". These look like twist drills, but have the tap threads on the first 1/2 of the bit. So I drill my starter hole and then use the fast spiral tap to do the tap.

I'm looking for the speed I should set the drill to. In this current project, I'd love to be able to use a hand drill rather than trying to move the project to the shop and the drill press, so if you have hand drill tips that would be great.

I'm also good with "Hey, since you can use a hand tap, use that, just remember to use oil, it's only 4 holes."
