You get what you pay for?! No wayyy!!! Get outta town!!
Bought a 2" face mill on fleabay for 20 bucks. It came with 10 inserts. Which, big surprise, have no numbers on them. But the ad lists APMT1604PDER.
Anyways. I had to make an R8 arbor for it. That was a good lesson. Took the final cuts on the face mill arbor down to dimension in the mill to get rid of any run out.
So, it seems the 4 flutes are not even. Put a DTI on the inserts and they vary as much as .003.
I also have to just touch the inserts to the diamond stone to give it an edge cause there's a radius just before the cutting edge, so it just burnishes without sharpening.
So, as you can imagine, it doesn't leave a very nice finish. Did I likely buy a dud, or is there something I can do to save this mill? I'm gonna take the inserts out and test it again and see if it's just crummy inserts.
