KEHAOU CNC Tools HRC55 Solid Carbide End Mill for Aluminum and Other Non Ferrous Metals, 3 Flutes, 45 Degree Helix, 6mm Shank, 3/4" Length of Cut, 2" Overall Length

1 star rating for the product description, undecided on the rating for the actual end mill. I'll give it 2 stars until I actually use the thing.For a 6mm end mill it seems pretty nice. there is a small taper to the shank from top to bottom so I won't be a bit surprised if there's a bit of runout once installed in a tool holder. The top of the shank is 6.00mm but tapers off to 5.95mm before the flutes start and measures in at 5.98 at the center.I was needing to get a 1/4" end mill quick and this was the only one with a delivery time that wouldn't leave me waiting until next week. Unfortunately none of the measurements in the description are correct. It's just a 6mm end mill with a 0.68" length of cut. Just barely too short to use for what I was doing.Overall I guess it's okay for a hobby machine and the price isn't much. I guess I'm just comparing it to the good stuff. If I had a home built mill where tolerances weren't important and had limited rpms I'd probably be buying these just for the price.
