To permit for these maximum rpm applications, cutting tools have to be precise and long lasting, or more accurately, predictable, especially in unmanned operations. They also have to be capable of holding tolerance at these high speeds, and resist deflection and vibration especially in applications with longer overhangs.

Balance, edge preparation, geometry and cutting tool (edge) material or grade all contribute to precision and life. Different tool shank materials also are to be considered and include steel, Densimet and carbide, with carbide being the most rigid.

 Since cutting tools wear at varying rates during the machining process, manufacturers have to know the usable lifecycle—the point at which the cutting tool needs to be indexed, reground or replaced depending on the style of tool. Knowing and understanding predictable tool life helps shops make the most out of their cutting tools and, more importantly, get the most from the plant floor.
