    that's quite long for a 1/8 bit... you'll need to be fairly gentle with DoC to avoid bending the tool. Insert the tool so that you have minimum necessary exposed shank to help minimise flex.

    Then try something more like 18k rpm, feed down to 600ish and I wouldn't go much beyond 0.5-1mm DoC at first with a tool that long/thin. You could try a bit deeper with adaptive type strategies (although perhaps limit the step over it allows to reduce loading on the tool.
