My millby Russ KeplerI know my mill's had some hard times, and I'm pretty sure the original bearings are still in there. So here's a cut to compare to:
1/2 newish carbide about 1000 rpm climb milling .060 deep x .5"(ish) high (not sure about the IPM, was making decent chips) running a MicroDrop lubricator to blow chips clear.
In person the cut looks a lot better. I wouldn't question the finish on a commercial part.
