This is an awesome idea. Sound like fun.
I'll DM you.
I'll DM you.
Little fear of that, I appear to have grossly underestimated how many by a factor of 2..... LolYou know in a couple years, you're going to be working on something, and need an 8mm tap but won't be able to find one.....
Thanks again. I'll have to dig through my paperclip collection to send a nice one in return.
.... well, I dropped the ball a bit today and I think I will be sending the next batch out on Saturday, rather than Friday as planned. Still plenty of taps left if anyone is still on the fence......Been sick and travelling and never got my you know what together on this one ...... but tip o' the hat to you on the whole thing, a fun idea.
You are correct. Spiral flutes are much better for power tapping, as they like being held rigidly, and lack the self aligning taper of spiral points and plug/hand taps. They are a bitch to start by hand, but can be done if in a pinch, although I wouldn't recommend it. IMO the old plug/taper/bottoming hand taps of yesteryear are obsolete. And the only reason to still use them is because you still have some, I have a couple different sizes of the old 3tap style, but can't see me ever using them. Bottoming taps still have their place, but if one were to buy one type of tap for eternity I'd be buying spiral points. At home in a mill spindle, tailstock chuck, handdrill chuck, or tap wrench. They do it all. I also grind them flat to make bottoming taps from them when they do eventually dull. It's nice to catch them before they snap off in a hole and cause me an hour detour though.....Am i wrong in assuming that spiral taps would be more suited to power tapping due to the improved chip ejection?
