摘要： A drill bit includes a crown defining a central axis. The crown includes at least one segment. The segment includes a planar portion and a plurality of surface features continuous with and extending away from the planar portion. The surface features are discontinuous within the segment with respect to a first arced path defined at a first radial distance from the central axis.

摘要： Drilling tools include a bit crown and an integrated reamer. The bit crown and the integrated reamer can be configured with approximately equal drilling lives. The bit crown can be impregnated with abrasive cutting media and include one or more external flutes. The integrated reamer can be positioned at the base the bit crown and include one or more channels that align with one or more of the outer flutes. The channels can taper such that they increase in width as they extend away from the bit crown.

摘要： Impregnated drilling tools include elongated structures that provide enhanced properties. The drilling tools contain a diamond-impregnated cutting section that contains elongated structures made from carbon, glass, ceramic, and the like. The elongated structures can comprise tubes, fibers, or rods. In one or more implementations the elongated structures are nano-sized. The elongated structures can control the tensile strength and/or the erosion rate of the drilling tools to optimize the cutting performance of the tools. Additionally, the elongated structures may also weaken the cutting section in one or more implementations; thereby, allowing higher strength binders to be used. Such higher modulus binders can cost less and allow for tailoring of the cutting section to retain the diamonds for the desired amount of time. As the cutting section erodes, the elongated structures may also increase the lubricity at the face of the cutting section.
摘要翻译： 浸渍钻井工具包括提供增强性能的细长结构。 钻具具有金刚石浸渍的切割部分，其包含由碳，玻璃，陶瓷等制成的细长结构。 细长结构可以包括管，纤维或棒。 在一个或多个实施例中，细长结构是纳米尺寸的。 细长结构可以控制钻具的拉伸强度和/或侵蚀速率，以优化刀具的切削性能。 另外，细长结构还可以在一个或多个实施中削弱切割部分; 从而允许使用更高强度的粘合剂。 这种更高模量的粘合剂可以花费更少的成本，并允许切割部分的裁剪以将金刚石保持期望的时间量。 当切割部分侵蚀时，细长结构还可以增加切割部分的表面处的润滑性。

摘要： A down-the-hole assembly includes a housing having a central axis and a mechanical gear box positioned within the housing. The mechanical gear box is coupled to the housing such that rotation of the housing at a first rotational rate provides a rotary input to the mechanical gear box. A rotary cutting bit is coupled to the mechanical gear box. The mechanical gear box is configured to rotate said rotary cutting bit at a second rotational rate in response to that rotary input from the housing. The second rotational rate is greater than the first rotational rate. The mechanical gear box is also further configured to cause the rotary cutting bit to orbit about the central axis of the housing.
