Destruction of a nice endmill.


This is what the end of a nice endmill looks like after you snap it in half from chatter!

Seems like the edges failed from the chatter, then it started melting the steel which stuck in the flutes and them BAM off it went flying round the shop!

Luckily this is just a little guy, only 0.1875" in diameter.
