    I tried various cutters, speeds and feed rates with ali and the best cutters I found were these :- Sorotec - Werkzeuge. Cutter geometry seems to be the crucial factor. Downcut spirals didn't work as the main problems seems to be chip clearance. Rapid and light cuts seem to work better, with a spray of paraffin. I tried 1-cal cooking oil but it just made me want a bacon sandwich .
    Cheers,
