The cutters in the first picture are DeVlieg microbore inserts. Used in a boring bar they give you fine adjustment control. There are two different dials though the threads are all the same. One assumes the insert is at right angles to the centerline and the other assumes an angle. Can't remember the angle exactly but they change the number of graduations, making it an even number, and then calculate the appropriate angle so it's a little bit odd.

You can still get them, along with replacement dials, screws, etc. and different end shapes depending on the intended task.

I've seen specialized boring bars manufactured to turn multiple diameters simultaneously, presumably for production jobs.

Second row from bottom in your insert pics are KNUX inserts, left handed and right handed inserts. Great ones for really removing material and still widely available, though I prefer something else.

You can make your own heads they just screw in at 45. I have made a few. And still have one in my kit.

Well, you're not claiming a gloat or telling us how much you paid, but those cutters are neat enough that I've got to say it...YOU SUCK!

I used that type of cutter in boring bars at my first machine shop job in 1972 they were used in a NC Burgmaster to make truck axles. Yes I did mean to type NC and yes I am that old.

I can beat that one. I used them, or something very similar, circa 1958:)

TGTool was clearly too modest to post this link to a most informative thread about those micrometer boring insters:
