A cutting tool comprising:
- a tool body having at least one slot therein;
- a cutting insert disposed in said slot and having a body portion defining at least one side edge having a first geometrical configuration and a cutting portion;
- and
- at least one attachment ring fixed relative to said tool body, said attachment ring having a rib defining a complimentary geometrical configuration for engagement with said first geometrical configuration of said cutting insert thereby creating an interference fit and applying a holding force to said first geometrical configuration of said cutting insert to precisely position said cutting insert in said slot.
