Is anyone making Carbide expander mandrels for the Sinclair or K&M expander dies?

99% sure these drop into a Sinclair, let me go check:
Edit: confirmed, PMA carbide mandrel drops into my Sinclair die. Their mandrels/die is supposed to be compatible with Sinclair and 21st Century. They're very nice, they'll do custom grinds in carbide which is a really nice option to have. I do like the PMA mandrel dies, they aren't expensive and lock the top of the stem in with a hex screw - I prefer that over the cap on my progressive press just because it's easier to stick a hex key in to make sure it's tight rather than grabbing the knurled top and trying to twist it around next to other dies.

21st Century mandrels aren't carbine, but they come in 0.0005" increments if you need to get down to a very fine adjustment level. Also a great company to work with.
I don't know anything that works with K+M other than their own mandrels, they screw in. I have a couple of their dies so I can use their matched expander mandrel/turning arbor sets with my neck turning tools. Great tools just seems like they're a closed ecosystem.
