EANOSIC Extra Long CNC Spiral Router Bits with Up Cut 1/8 inch Cutting Diameter, 1/4 inch Shank Solid Carbide End Mill with Nano Coating for Wood Cut, Carving (3 inch Extra Long)

These 1/8" upspiral bit work better on the CNC than far more expensive name brand bits. I'm very happy with the durability of the bit; and the clean line of how it cuts. Will purchase these again when I'm in need.

I have used this for several projects now and it is still working as expected

I use 1/8" Upcut Spiral Bits on a 2nd toolpath to clean up small areas a larger bit will not get into. This bit worked very well for a Business Card I cut in Brazilian Walnut which is very brittle. I need to use the bit more to determine durability however it is very sharp and cut well on this project. I will update the review after more use of the bit. The cutting diameter of the bit measured 0.122" rather than 0.125". so if your making precision cuts you will need to allow for this in your toolpath setup.

Poor quality

As long as you don't push the feed rates you won't break the bit. Works perfectly fine and have been using it for lots of milling so far with great success. Super sharp and super straight.
