Got these for $24 on Amazon. Immediate need was for some 5/16 - 18 Helicoils.
One of the big ones did accept the tap. I say accept rather than fit. I don't think it could have been any more loose and still worked. But it did, so that's good.
The Helicoil insert tool no longer comes with a diamond shaped thumbscrew type drive (old one in picture). I hoped one of the small sockets would fit the new helicoil square drive. Nope.
