Yep - sure enough. I'd only checked in "miniatures". They're in the regular ball end mills.
The length of cut is listed as 0.012mm, which is surely a typo, as the pic shows the cutting
length is several diameters. It has a nice relief, too.

Yes, but my software won't do that shape, and it looks like they're usually larger.
Most of my ball end work is HO scale figures. Smaller is better.

I never drill a pilot hole. My draft operations are usually with center cutting end mill
(I guess), as they're either with a ball end mill or with a big 1/8" (OK, for me that's
HUGE) end mill. I don't know how to tell if this thing is center cutting or not.
How do I tell?
