摘要： A drill (20) having an elongated body (11) including a fluted land (12) and a shank (25). The fluted land (12) includes a plurality of radial grooves (47, 49, 51) of reduced material thickness formed therein to the depth of the flutes (27, 29, 31). The grooves (47-51) define discrete segments (53, 55, 57) of the drill (20). Each segment (53, 55, 57) has a facet (59, 61, 63) which has the relief of a drill tip (12) so that when the exposed drill tip (12) becomes dull, the segment (53) can be broken off at the notch exposing a successive, sharp drill tip. The drill (20) can have the cutting edges coated with an appropriate protective material such as TiN, titianium nitride, titanium carbide, titanium carbonitride or any other appropriate coating material to improve cutting and preserve the edge.

摘要： A taper tap for pipes of materials of high hardness, having a high durability and capable of forming a pipe taper female thread even of a material of a hardness of substantially more than 50 HRC. The sum Σr of edge thickness angles is around 130°, and each edge thickness is large enough to obtain high strength and rigidity. The rake angle α of a cutting edge (6) is about -20°, so that the tool angle (β) formed by the rake face (8) and the outer circumferential flank (9) is over 90°, improving the strength of the cutting edge (6). The bottom taper of a groove (4) is 1/16 which is nearly equal to that of a thread portion (2). Hence all of the rake angles α of the cutting edges from the small end to the large end of the thread portion (2) are the same, enabling all the cutting edges (6) to carry out the same cutting. The radius Df of the groove bottom of a front end portion (1a) is around 60 % of the outer diameter D of the small end of the thread portion (2), and therefore this taper tap is thicker than an ordinary tap, so that the pipe taper tap has a high strength, a high rigidity and a high abrasion resistance owing to such a structure.

摘要： A chasing tool for repairing screw threads, which includes a substantially prismatic body (2) with a bottom and a top surface, having on one end of the body a transverse, notch-like recess (4) opening into the top surface and serving as a support for the threaded component the thread of which is to be repaired, and extending in a direction substantially perpendicular to the direction of the notch-like recess, starting from the other end of the body, at least one slot (10) opening into the notch-like recess (4). The tool further includes a handle (16) extending from the bottom surface of the body and is attached thereto with one degree of freedom in rotation. The handle is provided with an axially directed bore (18, 20), at least a portion of which is provided with an internal thread. There is also provided at least one arm (24) fitting into the slot with clearance and hingedly articulated, at a first point, to the body at a region thereof close to the other end, and at a second point, to the terminal portion of a rod at least a part of whose length is provided with an external thread matching the internal thread of the bore in the handle, the free end portion of the arm projecting into the region of the notch-like recess and is provided with thread-chasing means.
