    摘要： The present invention provides a method of surface decarburizing a cemented carbide cutting tool. The tool is placed in a protective environment. The tool is heated to an elevated temperature of between 600-1100 degrees C while in the protective environment for a period of 15-120 minutes. In another aspect of the invention, a drill is provided having a drill body (13) which has a cutting tip, an axis of symmetry, and a plurality of flutes (15), wherein the flutes (15) have a rake surface (17) at the cutting tip. The cutting tip comprises a plurality of side blade between the flutes (15) and joined at a web. A plurality of flank surfaces (27) extend from an outer diameter of the cutting tip to the axis of symmetry and a plurality of primary cutting edges (20) are present at the intersection of the flank surfaces (27) with the rake surfaces (17). The primary cutting edges (20) include either an angular or radius surface (21) or a combination thereof extending from the flank surfaces (27) to the rake surfaces (17).

    摘要： An abrasive tipped drill of .006 to .125 inch diameter is provided for drilling holes in printed circuit boards. A composite sintered abrasive tip of cemented carbide and diamond or cubic boron nitride is formed such that the carbide can be ground away to expose the abrasive as the cutting surfaces of the drill. A shank of tough material having high transverse rupture strength is provided with a reduced section which forms the body of the drill. The tip is secured to the reduced section and flutes are ground overthe combined length ofthe tip and reduced section.

    摘要： The problem to be solved for a small-diameter drill as an object to be improved is how to restrain reduction in the strength of the outer circumferential portion of the cutting edge without providing a return portion while assuring sharpness of the outer circumferential portion of the cutting edge without an insufficiency, as well as how to achieve favorable machining accuracy and favorable chip processing performance. A small-diameter drill having a diameter of ϕ3mm or less and the end that has undergone cross thinning is provided such that in a front view, a flute portion cutting edge 4a is curved in concave with a degree of concavity d with respect to an imaginary straight line in a range of 0.5 to 2% of a drill diameter D, the imaginary straight line connecting the radially outer end P of the flute portion cutting edge and the radially outer end Q of thinning portion cutting edge, the ratio of length B of the thinning portion cutting edge to length A of the flute portion cutting edge is set to 0.6 to 0.9 : 1, and in an axially perpendicular cross-sectional view, curvature radius R1 of a heel-side flute surface of the flute is set to be smaller than curvature radius R2 of a flute surface along the flute portion cutting edge.

    摘要： A thin-film solar cell defect repairing tool of the present invention is configured to be rotated while being held by a chuck (16) disposed in a head of a processing device for insulating and isolating a local defect caused in a thin-film solar cell. The tool includes a shank (35) and a blade end (36). The shank (35) is formed on an end of the thin-film solar cell and is held by the chuck (16). The blade end (36) is formed on the other end of the thin-film solar cell and includes a blade (36a) for processing on the edge thereof Further, the blade (36a) of the blade end (36) is formed with a predetermined width in a position away from the rotary axis of the tool.
