Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the narrower the channel for chip evacuation.

*The thread mill used must have a relief angle greater than that of the multi start thread's lead angle in order to machine the thread. When the thread mill is rotating does it not become a disc and relief angle on the tool has no effect? The relief is created from the difference in the tool diameter verses thread major diameter.

An indexing head, also known as a dividing head or spiral head, is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions.Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines.

mill work that requires great accuracy. An edge finder helps in finding the edges. •800-1200 spindle RPM is recommended. •To use an edge finder, slightly offset the two halves so they wobble as they spin. •Slowly move the workpiece towards the edge finder. •The edge finder will center itself, then suddenly lose concentricity.
