Would any of you learned folks care to explain to me what the difference and uses of a centercutting and non- centercutting endmill would be?
Thanks,
Pat

A centercutting mill is configured such that it can be plunged straight into the work because it can cut with its center. A non-centercutting mill typically has a little hole in the center which where it was held by a center during the grinding process, and thus can't be plunged into the work.

Typically two flute endmills are centercutting, endmills with more (3 flute, 4 flute etc) may or may not be centercutting, you have to check the bottom and see.

I'll see if I can dig up a picture or two that people have posted in the past to show the difference.
