Anything with a bearing is out automatically. The straight ones might be alright, but it really depends on what you’re going to be using them for. I’ve been thinking about making a swivel plate for my computer mount in the shop. I was planning on using one of those round nosed router bits to cut a channel for some marbles to act as a bearing. I also don’t think estlcam has the ability to use bits that aren’t straight, so you’ll need to use fusion360 for that as well.
