Tested a worn out .375 end mill on a piece of 304 stainless yesterday

I figured I could squeeze one more part out of it and it snapped 2 minutes in, sending the insert flying across the shop. Has anyone else had a tool decide to give up in the most dramatic way possible?

Wait, you had an end mill with an actual insert on it?

Is that the same one you see in those old-school Indexable end mills, @morgan_ramirez?

My uncle tried using one to carve a turkey last Thanksgiving and chipped his countertop.
