Abstract

A thread milling insert includes a plurality of teeth longitudinally spaced along an edge of the insert, each tooth having a cutting edge at a tip of the tooth, a longitudinal distance between any two cutting edges being at least two times greater than a height of any tooth. A method of thread milling a workpiece involves providing a tool (23) with a thread milling insert (37), rotating a tool about an axis of the tool, the tool having a tool holder and at least one cutting edge arranged radially relative to the axis of the tool. At a plurality of circumferential positions about an axis of the workpiece, at least one of the tool and the workpiece are moved relative to each other in a direction substantially perpendicular to a direction of the axis of the workpiece while simultaneously moving at least one of the tool and the workpiece relative to each other in substantially an axial direction of the workpiece so that the at least one cutting edge forms a plurality of recesses in the workpiece, the plurality of recesses defining a helical thread.
