If you spin it too fast it splays out and is useless from then on.

For a flat surface - yes the 6 or 8mm HSS uncoated cutter from ArcEuro, when they have them.
Hi

Its flatness I need. I'm going to run some tests this evening. Bare in mind my machine is a china cnc 3040 so not the greatest thing. I've got a quite a few endmills I'll upload some images so you can see.

I'm only a hobbiest and still working on feeds speeds and general use of the machine. My time is very limited these days but I'm doing things in small drabs.
