    I have a few of these - http://www.ebay.co.uk/itm/371406148992 - they are cheap and not advertised as anything special. I bought them initially for plastics, but then tried them on Aluminium and found they were great.
    Last week I had some small parts to make in 304 Stainless from 12mm rolled stock and thought "What the heck!", loaded up a single flute (I did re-grind the tip to what I felt should be a slightly more robust form) and it proceeded to carve out my parts seamlessly.
    I used air for cooling and chip clearance plus mist lubrication,

    You think that's too expensive? You're not a Model Engineer are you? :D

    Thanks. Im still hurting from breaking two fairly expensive roughing end mills. Mostly my own fault and not having enough spindle power. Having a some other options to mess around with will be good. Ill order a few of these and try them.

    I am happy with the APT supplied end mills. I'm getting great finishes with the 10mm 3 flute endmill from them but they arent cheap. The roughing mills are expensive too (35ish for 10mm) but they work well (if you dont break them).
