Default Shelf Pin Holes

When doing shelf pin holes on the cnc, what type of router bit do you use? Upcut, downcut, or regular endmill. I thought that I read somewhere that a downcut endmill could cause a fire.

I've used a compression bit with success, but made sure to peck drill. If you try a downspiral without peck drilling, be sure to be nearby with a fire extinguisher.

I use a .250 end mill One single down cut to depth and your pins will fit perfect
