A threading insert is provided of a type that includes a mount portion and a plurality of arms radiating therefrom that each forms a pair of cutting edges, which is rugged, facilitates accurate positioning of the insert on the tool holder, encourages reliable breaking of cutting chips, and enables internal threading in a small diameter hole. One insert includes four arms (34-40, Fig. 3) radiating from a mount portion (24), with each arm having a radially outer edge (52) and a pair of opposite sides (54, 56), and forming a cutting edge (58, 60) at the interception of each side with an end of the outer edge. The mount portion has four flat locating surfaces (42-48) lying at the sides of an imaginary square, with each locating surface lying between a pair of arms and with there being an obtuse angle (D) between each locating surface and an adjacent side of an arm. The side of each arm extends only a short radial distance before intersecting a flat locating surface, which results in rapid breaking of chips and there being a considerable distance between a central hole in the insert and each locating surface to avoid insert breakage. Each arm outer edge subtends an angle of no more than about 30°.
