Abstract: A tool includes a tool body extending along a tool axis, and a thread protruding in a direction away from the tool axis on an outer surface of the tool body and provided in a spiral shape about the tool axis. The thread includes a first region located on one side in a spiral direction and a reference region located on another side in the spiral direction with respect to the first region. The first region includes a one-side tooth flank that is a surface on one side in a tool axial direction and an other-side tooth flank that is a surface on the other side in the tool axial direction. The reference region includes a one-side tooth flank that is a surface on one side in the tool axial direction and another-side tooth flank that is a surface on the other side in the tool axial direction.

Abstract: An insert portion (3) of a thread mill (1A) is fixed to a leading end portion of a body (2A) using screws (8). The insert portion (3) is configured by overlaying an insert (4) for finish machining and an insert (5) for rough machining. On respective mating faces of the inserts (4, 5), convex portions and concave portions of the mating face of the insert (4) are overlaid with concave portions and convex portions of the mating face of the insert (5). The thread mill (1A) can cut a female screw in a hole formed in a workpiece by performing right-hand cut down-cut milling, for example. The inserts (4, 5) simultaneously cut an inner peripheral surface of the hole, and the rough machining and the finish machining can thus be performed in a single pass. By the convex portions and the concave portions of the respective mating faces of the inserts (4, 5) being overlaid with each other, the inserts (4, 5) partially overlap in their respective thickness directions. As a result, a protrusion length of the insert portion (3) can be shortened.

Abstract: A method for producing a thread in a workpiece can include producing a preliminary thread by removing material from the workpiece (e.g., with a cutting action), which produces a preliminary thread profile having two preliminary thread flanks and a preliminary thread root connecting the two preliminary thread flanks. The method can also include producing, in at least one second working step, a final thread having a final thread profile, which has two final thread flanks and a final thread root connecting the two final thread flanks. The final thread can be produced by plastic pressing-in of the material of the workpiece at least in a section of the preliminary thread profile by a predetermined volume. In one implementation, at least one of the preliminary thread flanks and at least one of the of the thread-forming profile are include at different inclination angles from each other.

Abstract: An annular thread-whirling head is disclosed, wherein, projecting over its periphery, indexable inserts are mounted in recesses in a first plane and are connected directly to the thread-whirling head. The plurality of indexable inserts lies with an indexable insert surface on a bearing surface of the recess, in a manner such that the indexable inserts are individually accessible, and may be assembled and disassembled in a simple manner by way of a fastening element. The produced swarf per indexable insert is minimized by way of the plurality of used indexable inserts, and the service life or the performance of the thread-whirling head is increased. Recesses may also be provided in a second plane so that, apart from a plurality of indexable inserts in a first plane, one may also arrange and fix a plurality of indexable inserts in a second plane, offset parallel to the first plane. A thread-whirling head with indexable inserts in a first and a second plane permits the manufacture of multiplex outer threads in one passage.

Abstract: A thread mill that is to be moved along a helical interpolation path while being rotated about an axis of the thread mill in a rotating direction, for forming a thread in a circumferential surface of a workpiece. The thread mill includes a cylindrical main body having (a) at least one spiral flute formed in an outer circumferential surface of the cylindrical main body, and (b) at least one cutting edge each provided by a rear-side one of widthwise opposite edges, as viewed in the rotating direction, of a corresponding one of the at least one spiral flute. Each of the at least one spiral flute extends in a direction opposite to the rotating direction as viewed in a direction away from a proximal end of the cylindrical main body toward a distal end of the cylindrical main body. Also disclosed is a method of forming the thread by using the thread mill.

Abstract: A milling tool for thread-milling and boring has a milling region with thread-milling cutters disposed on thread-milling teeth, and bore-milling cutters disposed on an end face. The tool regions where the milling cutters are disposed are made of hard materials. The thread-milling cutters have a rake angle. The tool is successfully used to mill high-strength materials. The rake angle of the thread-milling cutters is zero or negative, and a coating of hard material is present in the region of the milling cutters. The combination of features including the use of hard material in the cutting region of the tool, the provision of a coating of hard material in the cutting region, and a zero or negative rake angle, enables use of the milling tool for thread-milling and boring with high-strength workpieces without problems and without experiencing high wear.

Abstract: A fastener which can be utilized with advantage as a bone screw or another osteosynthetic force transmitting member, instrument or accessory has a thread with two flanks each having a first section adjacent the crest and a second section adjacent the root of the thread. The second sections jointly include or consist of at least four concave portions having different radii of curvature and gradually merging into each other. The first sections make angles of at least 40.degree. with a plane which is normal to the longitudinal axis of the thread. The first and second sections of each tooth flank are separated from each other by an imaginary cylinder having a diameter which matches the pitch diameter of the thread and a longitudinal axis which coincides with or is at least close to the longitudinal axis of the thread.
