Tapmatic RX 50 Self-Reversing Tapping Head, #6JT Taper Mount, #6 - 1/2" and M3-M12 Capacity

Great product but the day i go to buy the rx50 it goes up 100 dollars. Litterally in my cart.

Given the cost of this device, I deliberated long and hard before springing for one. I am really glad I did. I run this in a vertical knee mill (Bridgeport knockoff) on lots of small R&D projects. There is a bit more set up compared with running a hand tap, but the result is a square entry every time and the actual tapping process is a fraction of the time compared with using a hand tap. I wasn't even sure how to operate this properly, but there are a number of helpful videos on YouTube to get you over that hump if need be. Be aware that you need the right sized rubber flex collet to accommodate the shank size of the tap you are running. I've been able to cover the gamut from 6-32 to 1/2 with just two collets (it comes with one and you have to buy the second larger one separately).

Awesome product. There a few unclear aspects of installation of the flex collets, but support from Tapmatic resolved these concerns well. The second most expensive tool I have ever bought and worth every penny.
