Well too, you must also keep in mind that there are different types of carbide inserts. That is, different hardness and structure for specific materials; an insert for stainless will be quickly destroyed by cast iron and vice-versa. You will have to have a 'supply' if you intend to use carbide indexable cutting tools and they are all different.
Use high speed steel with a percentage of cobalt and you can walk up to a standard pedistal grinder to sharpen it.... It hurts to throw away an insert that appears OK but will not cut to any finish. High speed tooling will always be the standard standby and the best for a home shop. There are Micro 100 tools that will cut case hardened steel.
