I have a superior tap handle, but the fine folks that made it have foolishly never considered putting their name on it. I can just about assure you that you would like it better. It fits *everything* up to 1/2", holds on center, can be used in a drill chuck, or with a spring loaded center, and is just 1000% better than any other tap handle I've used. It put a slew of Starrets into dust collection when I got one.Hand tapping, blind holes in hardened material.
I've seen some other members advocate them from time to time, perhaps one of them could chime in with the manufacturer. (A machine shop in the U.S. that made them for their own use, then decided to market them. - Nevermind, found it!
Also, they're simply amazing for tiny taps - the best thing I've tried there as well.
Made somewhere in the Eastern USA. Their marketing is so terrible that I can't find them. ^H^H^H^H^H^H^H^H^H^H^H^H^H...

P.S. It's hard to see all of its virtues, read carefully. I've got $1 that says anyone that owns one will echo my sentiment.
