The one on the right, you dial in the approximate diameter and the angle knurling wheels cut material rather than trying to cold form it, very little pressure required.
Get a 3 wheel one
I read an article in a magazine recently about making your own "cut knurling" tool. I'll see if I can dig it out and will post a reference to it.
As and when.
For example:

Not very good, but it works. I should have used a finer knurl.

I'm sure I've posted this before, left to right, good, better, best.

nice job on those. Assume they’re two hole pins for pipe flanges?
Yep. Exactly why I bought mine in from the states, £50 you can’t make a pair for that.Thanks Brad. Yes, they are. Made for an ex-member a few years back. They were a right bugger to make. I only had hot-rolled 1" bar that, depending on position, varied in cutting characteristics between plasticine and diamond.
