I just had a quick glance at the linked site, as a toolmaker by trade my advise would be spend $20 and buy a proper machine tap, not the cheaper hand tap. These hand taps are real easy to break. You want a HSS machine tap, and a proper tap wrench (starrett make a nice small one but for one use it might be overkill) just avoid a ratcheting handle, tapping something this small requires the work piece in a vice and two steady hands!!! If this is your first tapping this small I would suggest you get a piece of scrap stainless steel to practice with. Good luck!!
