摘要： A cutting tap is provided which can form an internal thread with high accuracy even when a prepared hole for the internal thread has an inner periphery of which the dimensional accuracy is low. The cutting tap includes thread ridges (5), roots (8) formed between the respective axially adjacent pairs of thread ridges (5), and a plurality of deburring thread grooves (10) arranged at a constant pitch toward the axial front side of the cutting tap from the rearmost ones of the roots (8) in which the deburring thread grooves (10) are formed, and formed such that a groove bottom diameter (d 3 ) of the deburring thread grooves (10) gradually decreases toward the axial front side of the cutting tap. The respective deburring thread grooves (10) have groove bottom diameter (d 3 ) reliefs by which the groove bottom dimeter (d 3 ) gradually decreases from the front side toward the rear side of each deburring thread groove (10) in the rotation direction of the cutting tap, the groove bottom diameter (d 3 ) reliefs being set to be larger than effective diameter (d 1 ) reliefs of the thread grooves (5).

Um das Werkzeug so auszubilden, daß das Gewinde (1) im Einlaufbereich einwandfrei hergestellt wird, ist am in Bohrrichtung rückwärtigen Endbereich des Arbeitsteiles (4) eine Entgratschneide vorgesehen, deren Arbeitsdurchmesser größer ist als der Kerndurchmesser der Gewindebohrung. Die Entgratschneide sorgt dafür, daß am Ende des Gewindebohrvorganges der erste, unvollständige Gewindegang zumindest teilweise abgeschert wird. Mit dem Werkzeug ist sichergestellt, daß das in die Gewindebohrung einzuschraubende Bauteil seine Funktion einwandfrei erfüllt.

摘要： Tapping tool used for machining holes as cast in castings. The tool has cutting edges (4a to 4d), a guide portion (3), a tapping portion (2) and a shank (1) extended to the tapping portion. The holes as cast are face-cut and drilled with said cutting edge to make holes before threading, then finished by reaming with said guide portion, and cut into female threads with said tapping portion. Highly accurate female threads can be made readily and rapidly, because of perfect alignment of the center line of the hole before tapping with that of the tapped hole.

摘要： Disclosed is a tap with a drill wherein three drill blades (26) and three threading edges (24) are respectively provided, three oil holes (28) are provided to penetrate in the axial direction, the core diameter (W) is set in a range of 0.25Dt-0.33Dt, a chip discharge groove (22) is provided with a negative land (22a) swelling into the groove, and since both the radial rake angle (ϕ1) at the outer circumference of the drill blade (26) and the radial rake angle (ϕ2) of the threading edge (24) are negative, a female screw (52) can be continuously cut practically while a rough hole (50) is cut under a state of being decentered from a hole-as-cast (46) by synergistic effect thereof even if the pressure of cutting fluid being supplied through the oil hole (28) is as low as 2 MPa or less.
