We bought these to machine 17-4 h900. They far and away exceeded my expectations. Tool life was longer than many others we have used. Sounds crazy but I would put these up there with Robb Jack or Sumitomo. Damn good end mills.

Very high quality End Mills. Will cut through anything. I've used them on hardened Grade 8 and above steels. Cut's like butter. Just take small passes and use lubricant. They will go through anything!! Little on the pricey side, hopefully they'll drop their price by 5%-10% to be more competitive with others here on amazon.

Purchased these to cut slots in wood, copper, and brass bolster material for the custom knives I make. These have been great little end mills. I broke one of them, but that was completely user error. make sure you know how to use the tool before you blame the tool.

Actually I'm very satisfied with the quality of the endmill so far. Only used once to mill plastic components so far but time will tell if it is a quality tool or just another pot metal part.
