Picked up a pretty stout fly cutter by Suburban tool. It has a one inch square cutter holder. I still need to fiddle with speeds and feeds but here is a piece of D2 cut .005 deep, 600 rpm, 3 IPM. The D2 was less than half the diameter of the cutter which wasn’t optimal but the finish looks promising.
I first tried .005 deep and followed with a spring pass, but not surprising, the carbide didn’t do well on the spring pass.
