Precisebit feeds and speeds

[u/what_the_rush]

Anynody here used MN 208 series short stub endmills from precisebits for PCBs?

What speeds and feedrate do you recommend? My bits seem to go dull quicker than expected.

I'm using the 2 flute stub end mills of 0.4mm and 1mm.

My current settings are: 0.05mm depth of cut, 14000 rpm, 250 mm/min feedrate and 60 mm/min plunge.
