APT High speed, high hardness end mills - anyone used them?

[JAZZCNC]

Now I have a couple of the above mentioned cutters which might do the job, but has anyone ever tried them on stainless, and if so what sort of DOC and feed worked best please?

Nobody can answer that,.! You haven't said the tool size for starters and APT makes lots of different cutters in various grades of materials and with different coatings.
However, even if you had given that information every machine is different and they don't know anything about your machine so at best it could only be a ball-park figure. Stainless can be bare to cut at best of times so trying to advise someone without any of this info is impossible.!

I have 6mm and 4mm High Speed, High Hardness cutters (as per the thread title) which APT recommend 16K and 20K RPM for which should work OK with my spindle which gives constant power between 12K and 24K.

Not being funny here but you can't ask questions about feeds n speeds and expect any sensible reply if you don't give all the details. You say 4 and 6mm but no mention of # flutes. Then you still have the machine to factor into the mix.? Is this a router with 2.2Kw spindle.? or is it a mill.? These make a big difference to how you would tackle this job and esp this material.! . . For instance, I wouldn't even attempt to try to cut Stainless with a router unless it was built like a brick shit house.!
