Abstract
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.
