Positive rake will give lower cutting forces which is better in most cases for the home shop machinist. The only advantage of negative rake tooling is longevity and sometimes being able to use more edges on the insert (largely a factor for lathe tooling).
I hope this has helped.

I will contact the seller and see what I can find out about the negative/positive rake. What would you call a “high positive rake” in degrees?
My mill only has 1.3 HP (1000 watts) and the largest recommended end mill is only 16mm but I am unsure how this would apply to an indexable?

That’s good to know thanks
I am happy to buy from the US so will do a world wide search but in the mean time if any one would like to make a recommendation on a reasonably price quality tool I am all ears. Any links would also be appreciated.
Thanks,
John
