I've been looking at catalogues of indexable milling tools and I've got to say there is a huge range of choices with regards to insert shape, material, rake, number etc.

Can anyone point me towards a guide for selecting such tools? Along the lines of:

this feature is best for roughing cuts/finishing
this feature is best for cast iron/aluminium etc
this feature is intended for general use
select more/less inserts for.....

You get the idea. The catalogues have a few pointers but mostly it is a bit of a mystery as to what each tool variation is intended for.
