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.
摘要翻译：一种具有细长体（11）的钻头（20），所述细长体包括凹槽刃带（12）和柄部（25）。凹槽（12）包括多个材料厚度减小的径向凹槽（47,49,51），其形成在凹槽（27,29,31）的深度处。凹槽（47-51）限定钻头（20）的离散段（53,55,57）。每个节段（53,55,57）具有小面（59,61,63），小面（59,61,63）具有钻尖（12）的浮雕，从而当暴露的钻尖（12）变钝时，节段（53）可以是在切口处断开，露出连续的尖锐钻尖。钻头（20）可以具有用诸如TiN，氮化钛，碳化钛，碳氮化钛或任何其他合适的涂层材料的适当保护材料涂覆的切割边缘，以改善切割和保存边缘。

摘要： A threaded fastener (10) is having a raised area or bump (16) on a thread flank. The flank can be positioned on the nut thread (12) or on the bolt thread (14). The bump (16) forces the mating threads at least on one flank to have near zero tolerances along the pitchline of the threads and thereby eliminating play. A threaded repair insert (60) having at least one raised area on a threaded surface (62) also is provided.
摘要翻译：螺纹紧固件（10）在螺纹面上具有凸起区域或隆起（16）。侧面可以位于螺母螺纹（12）或螺栓螺纹（14）上。凸块（16）迫使至少在一个侧面上的配合螺纹沿着螺纹的节距线具有接近零的公差，从而消除间隙。还提供了在螺纹表面（62）上具有至少一个凸起区域的螺纹修理插入件（60）。
