Today I cored a piece of mostly dry Dalbergia Sisso - East Indian Rosewood with the new carbide cutter from OneWay.
I used it first to cut the outside curve. Then I moved the base to the right and back and started to core the largest bowl.
Part way down I stopped, leaving the base in place and switched to the smallest cutter set. I put a new standard cutter on it and managed to cut in less than an inch before it started to smoke. I changed out to the carbide cutter and it worked nicely till the center core popped out.
I went back to the larger set and finished the coring without issue.
I added a couple of pictures of the shavings that I got from the carbide. All in all, an EXCELLENT investment
The finish was smoother than any coring I've done with the high speed steel. I'll probably finish the set over the weekend.

Image 2) Shows the trimmed off top of the blank with the cutter set to make the outside curve of the bowl. I've only done this a couple of times before, but I wanted to give the carbide cutter a real workout.
Image 3) just shows the same image with a closeup of the cutter to the right.
Image 4) shows the core to the left where I went 1/2 way to the finished cut and the cut I started with a new high speed steel cutter that didn't cut very easily and, in fact started to smoke while making dust.
Image 5) Shows the completed cored set stacked together
Image 6) Shows the bottoms of the cored set. I left the largest one on the chuck so that it would remain true. I'll use a "jumbo jaws" to hold the cores while I turn a tenon on them.
Image 7) Is just some shavings that piled up on the coring base
Image 8) Shows the shavings still balanced on the cutter as the cutter is removed from the blank. You need to clear those shavings fairly often to make sure you don't jam up the process.
