Abstract
Cutting tool systems including a cutting tool and cutting inserts are disclosed. The cutting inserts have indexable cutting edges and seating face features which enable uniform facets along a portion of each cutting edge of the indexable insert. The first and second seating face surfaces of the cutting insert each comprise control cavities that adjoin the cutting edge facet surfaces. Each control cavity allows its corresponding cutting edge to have a facet width that is defined by the cavity to provide uniform surfaces. The control cavities reduce and limit the amount of the first and second seating face surfaces that need to be ground. Methods of making such cutting inserts are disclosed.
