This invention relates to cutting tools used to machine materials to produce new surfaces and chips of removed material. Embodiments of this invention allow round rotating cutting inserts to be used in a more economical way, with improved accuracy, with improved sealing, and with greater ease of use. The rotary support device and cutting inserts may be used in either radial or tangential mounting types of cutters. It also provides a built-in, fully sealed means of fine adjustment of the cutting insert that is useful in some applications.

Rotary cutting insert and support device

A milling tool includes a body which is rotatable about a first axis. At least one cutting tooth mounted on the body having a cutting edge for cutting about the first axis. A wiper tooth extends from the mill body. The wiper tooth includes at least at a portion having a peripheral surface about the second axis and the peripheral surface intersects a face surface defining a cutting edge that is round about the second axis for cutting about the first axis. In some embodiments, the peripheral surface, the face surface and the cutting edge are formed on an insert that is mounted the mill body.

A boring tool including a body, at least a cutting element mounted to the body, and at least a pad spring mounted to the body.

Stabilization of boring tools

A cutting tool includes an insert defining a flank face, a rake face, and a cutting edge between the flank face and rake face. The cutting tool includes micro-nozzles formed in at least one of the tool body and the insert, and aimed at the cutting edge. Each micro-nozzle generates a micro jet of cutting fluid in close proximity to the cutting edge and adjacent to at least one of the flank face and the rake face.
