摘要： Reamers for use in core-sample drilling include PDC inserts. Such reamers with PDC inserts may be used to maintain borehole diameters, reduce deviation, and/or stabilize drill strings used in core sample drilling. The PDC inserts may be of different sizes and shapes and may be arranged around the reamers in various ways.

摘要： Core drill bits with long crown heights are described herein. The core drill bits have a series of slots or openings that are not located at the tip of the crown and are therefore enclosed in the body of the crown. The slots may be staggered and/or stepped throughout the crown. As the cutting portion of the drill bit erodes through normal use, the fluid/debris notches at the tip of the bit are eliminated. As the erosion progresses, the slots become exposed and then they function as fluid/debris ways. This configuration allows the crown height to be extended and lengthened without substantially reducing the structural integrity of the drill bit.
摘要翻译： 这里描述了具有长冠高度的钻头。 核心钻头具有一系列不位于表冠尖端处的狭槽或开口，因此封闭在表冠的主体中。 槽可以在整个表冠处交错和/或阶梯。 当钻头的切割部分通过正常使用而侵蚀时，钻头尖端处的流体/碎屑缺口被消除。 随着侵蚀的进行，槽变得暴露，然后它们作为流体/碎屑的方式起作用。 该构造允许冠部高度被延伸和延长，而基本上不会降低钻头的结构完整性。

摘要： Diamond-impregnated cutting tools including fibers and drilling systems incorporating such tools are described. The cutting tools contain a diamond-impregnated cutting portion that contains fibers made from carbon, glass, ceramic, polymer, and the like. The fibers may be used to both control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may also weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion. Using the fibers allows the cutting tools to last longer and make them safer and more economical because they need to be replaced less often.

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.
