    Hi Gregor,

    I think in general people experiment and find out what cutters work best for them or their machine. I believe when it comes to this kind of tooling, you get what you pay for, though there have been quite reasonable results from less costly cutters.

    There is a nice post by Steve showing the results from cutting aluminium with coolant and a selection of 5 different cutters located in his build log here: My Build - I blame you lot for this....!

    You do also have the option when working with wood to use standard router bits; they also work for aluminium as well so I’ve read. The ER11 collect on your machine may impose some limitations on what size cutters you can choose however.
