Good day all

I have just got a few HSS 8% Cobalt 3 Flute 90Deg Countersink (http://www.cutweltools.co.uk/files/ww/3%20flute%2090%20degree%20countersink.pdf) cutters from cutwel.

Has anyone here also used them or any other countersink cutters, and if so what sort of speeds and feeds are you using for aluminium?

Thanks for your time.
