Makes NPT threads nicer
Can you just drill a hole and run an NPT tap through it? Sure. But this makes the threads nicer, and they seal better. If you run it in all the way, it even leaves a little radius and spotface to make the threads look nicer and work a bit better. I ran it by hand with a tap wrench. I think in my material (stainless) it would have chattered if I ran it under power. In softer stuff like aluminum or brass you can probably get away with it. Use plenty of cutting oil, like any reamer.

A must-have for your toolbox.
Anyone performing their own NPT female threads will tell you it's hard to drill a good starter hole since the final thread is tapered. This insures that the tap will enter the hole properly and not overstress the tap, assuming you use fluid and follow procedures.

Great price
A great price, but I have not tried it yet. So I can't really talk about quality and performance
