I want to try stock checkering.

I have bits smaller than that & a lot is down to the quality of the bits, the settings used & how rigid your machine is. I have snapped them but usually because I was trying to push them to hard.
What I tend to use the most though if I am using small bits are tapered ball nose bits, have them down to 0.5mm & you can get away with a lot more than you would using a straight shank bit of the same size

I thought that checkering had a flat bottom which was why I had suggested using an engraving bit with a flat tip, Mike-S who has a lot more experience than me put me right on that one
As I have said before I am probably way to conservative with my feed settings which is maybe why I haven't broken the tips off more bits but the machine plays a big part as well, especially with small bits, when was the last time you checked the run out on your spindle ? Even with a rigid machine to much run out will break bits
