I am considering this. Cutwel are doing a 'free' holder if you order 20 inserts. Around £150 landed cost. Not cheap however this might be more efficient than buying endmills in the longer run.

Thoughts? Suitability on a high speed spindle setup? From the supplied chipload per tooth, I should be pushing around 20K RPM and north of 6000mm/min (assuming I can power this much of cut).

Thanks
