    摘要： To provide a drilling tool and a method for manufacturing the same, with which electroconductivity is ensured between a tool point and a material being drilled, and any decrease in drilling quality can be minimized more so than with a non-coated drill. A drilling tool in which one or more helical chip-evacuating flutes (2) are provided, from a tool point to a base, in an outer circumference of a tool main body (1) having a coating film (5) covering a tool base material made of a cemented carbide, and one or more cutting edges (4) are provided at intersecting ridge lines of the chip-evacuating flutes (2) and a point relief (3), wherein a point of the tool main body (1) is provided with an exposed part (6) in which there is no coating film (5) and the tool base material is exposed, and certain ranges at tool-outer-circumference sides of the cutting edges (4) are covered by the coating film (5).

    摘要： The invention relates to a drilling covering (2), made from, or essentially made from a metal foil (8), for the mechanical drilling of microfine holes, in particular, in the production of circuit boards, which is characterised in that the metal foil comprises, on at least one outer facing surface, an essentially non-directional microtopography (10), with a surface roughness (16) of between 1 and 5 νm, preferably between 2 and 4 νm and a target value of 3 νm. Said microtopography permits an off-centre deviation of drilling by, at most, an amount corresponding to the order of magnitude of the surface roughness. The above may be produced by means of rolling, stamping, sandblasting, microetching, electropolishing or similar. Where desired the metal foil (8) can be laminated on a film (20) made from softer material.

    摘要： The invention relates to a reamer (10) comprising a shaft section (14) for clamping said reamer (10), and a neck section (16) which is rigidly connected to said shaft section (14) and aligned along a longitudinal axis (12), a frictional section (18) being designed at the free end of the neck section (16) and comprising a carrier section (20) which is rigidly connected to the neck section (16) and to which at least one cutting element (22) is secured. The carrier section (20) comprises at least one carrier surface (30), for the cutting element (22), which is arranged tangentially to the longitudinal axis (12), on the outer periphery of said carrier section (20).

    摘要： An arrangement for driving a rotary tool (17) is provided in which the tool shank (18) is engaged and frictionally driven by the engagement of three or more drive rollers (14, 15, 16). Axial movement of the tool (17) is accomplished by tilting the axes of the rollers (14, 15, 16) as permitted by flexible portions (84) of the shafts (78) which drive the rollers (14, 15, 16). The tool (17) is released by moving one roller (16) away from the other two (14, 15). A pressure foot (115) is provided at the bottom of the assembly reciprocated by a cam arrangement (139) to engage the workpiece (13) when the tool (17) is in operation. A position pick-off (103, 104) senses the axial position of the tool (17) so that the tilt angle of the rollers (14, 15, 16) can be controlled.
