Abstract: The invention discloses an improved tool and inserts for concurrently milling multiple splines on a round (rod) material. Replaceable inserts having teeth formed to have their cutting edges shaped in the arc of a circle are disclosed. The inserts each include at least two sets of rough milling teeth. The tool holder shank includes recesses which provide a common or universal unit for receiving various sized groupings, each comprising an insert, a wedge for securing the insert, and a supporting member for the insert.

Abstract: The invention discloses an improved tool and inserts for concurrently milling multiple splines on a round (rod) material. Replaceable inserts having teeth formed to have their cutting edges shaped in the arc of a circle are disclosed. The inserts each include at least two sets of rough milling teeth and a fine set of milling teeth. The tool holder shank includes recesses which provide a common or universal unit for receiving various sized groupings, each comprising an insert, a wedge for securing the insert, and a supporting member for the insert.

Abstract: A method of currently milling multiple splines on a round rod material. Inserts mountable on a milling machine are provided. The inserts each include two sets of milling teeth. The sets or sections of teeth are formed in the arc of a circle to enable milling multiple splines concurrently. The first set of teeth rough mills the grooves for the splines and the second set of teeth provides the finished milling.

Abstract: A tool for cutting tapered threads, said tool being mountable on a tool holder that is in turn positioned onto a spindle of a milling machine controlled by a CNC. The CNC rotates and moves the tool in a pattern to cut a tapered thread on a male connector. The tool includes a step or projection of slightly greater dimension than the threads, and at a position slightly above the threads. During the same operation that the threads are being cut, the tool severs the thin end of the tapered threaded connector to form a blunt end.

Abstract: A tool holder apparatus mountable on a machine spindle which apparatus is adjustable and provides a solid stable support for the tool holder to eliminate any gap or spacing between the end of a machine spindle and the support collar of the tool holder.

Abstract: A milling tool having replaceable straight elongated inserts that provide a helical cutting action. The tool has grooves formed at an angle with the longitudinal axis of the tool, the grooves have flat surfaces. Wedge means secure the respective inserts in respective grooves of the tool. The wedge means each have a plurality of apertures on the surface bearing against the insert, and coolant fluid under pressure is provided through said apertures to exit adjacent the cutting edge of said insert and against the work surface.

Abstract: A cutting tool comprised of tool hardened steel having a holder end and an opposite end. A series of axially extending slots are provided on the tool at an outer circumference of the opposite end. The slots each have a radially extending slot wall positioned so as to extend in a plane that intersects a longitudinal axis of the opposite end. Each of the slots also have a generally radially and diagonally extending slot wall confronting the radially extending slot wall associated therewith. Jig ground pins mounted in the opposite end and extended across a radially inner end of the associated slot. A series of cutter bits are mounted in the slots and bottomed on the jig ground pins positioned at the radially inner end of the associated slot. A series of cutter bits with one of the bits in each of the said slots.
