Ceramic Mills

Because of their speed advantage over traditional carbide tools, ceramic milling tools have gained increasing popularity in recent years. Indexable ceramic inserts and other ceramic machining tools may also be easier to use, as they often work without the assistance of coolant. Whether your operation is looking to switch to ceramic tools or to replace existing ones, Kennametal offers one-stop shopping. Kennametal ceramic inserts give you precise and true cuts throughout the lifespan of each insert. If your operation requires high feed rates or fast machining, ceramic inserts, end mills or shell mills may be the way to go. Choose from standard inserts and tools or let our design engineers recommend made-for-application solutions.
