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： Implementations of the present invention include drilling tools having axially-tapered waterways that can increase flushing and bit life, while also decreasing clogging. According to some implementations of the present invention, the waterways can be radially tapered in addition to being axially tapered. The axially-tapered waterways can include notches extending into the cutting face of the drilling tools and/or slots enclosed within the crown of the drilling tools. Implementations of the present invention also include drilling systems including drilling tools having axially-tapered waterways, and methods of forming drilling tools having axially-tapered waterways.
