pretty much useless after 1 hour cut.

After about an hour of cutting, this attachment will start to form bands and will not remove the cut material, so it needs frequent cleaning. Tried a second cut with a new nozzle and the same thing happened. I cut 1/2 poplar on X-Carve. The pieces I cut out had to be chipped and sanded hard to be smooth.

Pros
  • Slim design
Cons
  • Long delivery time

Not perfectly round but you get what you pay for

The end mills I received were not as good a ball shape as I had hoped. There is a flat spot on the end of the end mill (seen in the photos) and the radii do not match the sides of the end mill. Maybe the problem is how they form a spherical spout on it. It may not matter to your application, but you get what you pay for.

Pros
  • Everything is great!
Cons
  • Dear

Very brittle - plastic and only small hobby machines

I tried these bits on soft non-ferrous metal using the same CNC programs I use with other 1/8" carbide bits. The first one I tried ,the first was diving before lateral pressure was applied.The second broke within seconds.I've also done a lot of acrylic carving with the machine so I'll try them and update the review if they work.For now I certainly wouldn't recommend them for anything but very light work on small hobby machines.

Pros
  • Several competitors
Cons
  • unreliable
