Try removing one insert at a time. There may be one that is slightly higher (lower?) than the others. You should see the radial pattern of the cut, but it should be smoother than that. Of course, I use this cutter for metal removal, then a fly-cutter to pretty it up.I tried a variety of passes from either side, various speeds (hand feed only) various depths, WD40 and get good results but still some radial patterning. Is it realistic to expect none at all?
No marks at all is impossible. No matter how nice it is you'll get lots of folks telling you how to do it better. I think it looks good with a tiny bit of chip welding as was said. Even a perfect tram can lead to a bit of directional cut instead of cross hatch simply due to the bearings or flex.I tried a variety of passes from either side, various speeds (hand feed only) various depths, WD40 and get good results but still some radial patterning.
