Hi Phill,
Thank you for your reply. I am glad your cutters worked for you. I will have to try and source some 1 or 2 upcut cutters for future reference. I will try with the 4 flute I have unless I am told it is the wrong cutter and that way it will give me a comparison for when I get the cutters you mention.
Many thanks
Suesi
