I haven't had the chance to use the head, but I have used the cutters on my lathe. Nice solid tools. I look for cases to help keep things together and this kit is very complete. Good value for the money.
I bought this to bore a collet out to a custom diameter, and I've had a couple reasons to use it since then. It's a handy tool for small jobs, when you don't have every size of cutter on-hand. The slide and dials aren't particularly fine, but they're functional if you hold the tool to one end consistently, to take up any slop as you tighten. It seems to repeat nicely if you do.
This is the first time that I have used one of these... but it did a fine job, and it was easy enough to use. Seems to be pretty high quality.
