FWIW: I've ordered 0.25 and 0.5 inch wood bits from onsrud, harvey, vortex, etc,and the bits are right to my ability to measure them. (IE i can measure them to be within 0.0005 of correct size easily, and better than that better tools on the uncoated bits i have). I'm not sure who you are ordering from. (as for feed rate too high to use other geometries not sure what IPM you can drive that thing at. I would expect you could easily do 300-400ipm, which seems more than enough. I can get a very smooth finish from metalworking bits with no problem)
