ABSTRACT:
An improved cutting insert for rotary cutting tools is disclosed. The cutting inserts are characterized by a center bushing made of metal that is softer than the conventional sintered tungsten carbide or titanium carbide used for the cutting body of the inserts. The center bushing may be secured on each cutting insert by using braising, shrink fitting, oxidation bonding, or high energy bonding techniques. Additionally, conventional plating techniques may be used.
