    Abstract: PROBLEM TO BE SOLVED: To improve cutting performance of a drill part by making a twisted angle of the drill part larger, while suppressing a twisted angle of a twisted groove of a center hole drilling part not to make a cutting edge angle of the center hole drilling part too sharp.
    SOLUTION: This center hole drill 1 is successively provided with the drill part 2 and the center hole drilling part 3 and is provided with the twisted groove 4. In the center hole drill 1, a lead of the twisted groove 4 of the drill part 2 is smaller than that of the twisted groove 4 of the center hole drilling part 3.

    Abstract: PROBLEM TO BE SOLVED: To provide a tap which solves the shape distortion problem in a cutting edge thereof, and carries out female screw machining at a high speed, with smoothness, and with high accuracy. SOLUTION: The high-speed machining tap 1 is fed forward by a machine tool in synchronization with rotation, to thereby cut and machine the female screw by the cutting edge E of a screw portion 2. According to the machining tap, a bevel lead 2a of the screw portion 2 has chamfers CF at locations that each extend from the cutting edge E along a ridge line R between each of a following flank 2c and a leading flank 2d of a screw thread, and a crest face 2e.

    Abstract: PROBLEM TO BE SOLVED: To increase the service life, durability, processing rate of a thread cutting round die and to stabilize accuracy and quality.
    SOLUTION: The cemented carbide tip brazed thread cutting round die is so constituted that the end face of a base in a cemented carbide tip 11 is formed as convex partially cylindrical faying surfaces 12 which are plane symmetrical relative to a plane passing through the base width center line and the female screw central axis, setting the faying surface central axis CC1 which intersects at a position closer to the female screw central axis from the base end by a predetermined distance r shorter than the distance R between the base end face and the female screw axis to the base width central line BWC intersecting the female screw axis TC passing through the center in the width direction of the base and extends parallel with the female screw central line as the center, and is formed as concave partially cylindrical faying surfaces 15 which are plane symmetrical relative to a plane passing through the land width central line RWC intersecting the central axis SC of the block running through the center in the width direction of the land and the central axis of the block, and the convex partially cylindrical faying surfaces 12 and the concave partially cylindrical faying surfaces 15 of each land in the block are brazed.
