Poor end mill quality

Very poor quality. Bought 2 and both broke as soon as they hit the forged bottom which I milled. It didn't even sink 2mm when it cracked in the flange area. Wouldn't recommend it. And yes, I've been a gunsmith for over 10 years and it only clicked once and that was because of the rush. So the time passed slowly and quickly.

Cons
  • Mostly fine, but...
