But plenty of times I've used what I had on hand.
If you can using something in HSS or cobalt, it takes a much keener edge than carbide so you'll get a cleaner route
Also a single or two flute cutter, less is more for flute count has worked better for me in the past.
But if you are needing 90 or 60 degree cutters it may be a little more difficult to find those in HSS.
If you are doing enough volume to justify the cost, there are v-bit insert cutters available, that you might be able to use HSS instead of carbide inserts in.
But unless you are doing production it might not be worth the expense and effort to hunt everything down.
Not much of a direct answer I guess........
