摘要： Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to 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.

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. And with an extended crown height, the drill bit can last longer and require less tripping in and out of the borehole to replace 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。 并且具有延长的冠高度，钻头可以持续更长时间，并且需要更少的钻孔和出口的钻孔以更换钻头。

摘要： Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use 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 can be in any form, including chopped and milled fibers. The fibers may also be coated with metal, ceramic, or other performance-enhancing coatings. The fibers may be used to both control the tensile strength control 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. And 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.
