摘要： A cutting device includes, at least one stack of cutting elements attached to a cutter surface having, a first element and a second element attached to the cutter surface. A third element is attached to the first element and the second element. The three elements are sized and shaped such that prior to attachment to the cutter surface the three elements are restable in a stable manner on the cutter surface due to gravity alone. A plane-defined-surface defined by one of the two planes of a modified gilmoid of the third element positioned further from the cutter surface is oriented at an angle of about 35 to 55 degrees relative to the cutter surface.

摘要： Drilling tools include a bit crown and an integrated reamer. The bit crown and 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： A drill bit comprises a bit body connectable to a drill string at an first end, which bit body is provided with a longitudinal passageway extending from an opening at the first end to a port at a second end. The drill bit further comprises a closure element for closing the passageway, and when the closure element is in a closing position, the closure element is removable. Further, the closure element comprises a first and a second member that are movable relative to each other between an expanded configuration and a collapsed configuration, in which collapsed configuration, the closure element is retractable through the passageway to the first end.

摘要： A drill bit matrix is provided that contains a powdered abrasive material and a refractory metal powder in which the refractory metal powder is a coated powder in which each granule of the refractory metal powder is coated by a coating material. A core drill bit is further provided, containing a powdered abrasive material, a refractory metal powder and a steel tube onto which the powdered abrasive material and refractory metal powder are alloyed. The refractory metal powder is a coated powder in which each granule of the refractory metal powder is coated by one or more coating materials. A method is finally provided for manufacturing a core drill bit. First a matrix is formed by mixing together a powdered abrasive material and a coated refractory metal powder. The matrix is placed in a mould and a steel tube is placed on top of the mould to form a drill bit assembly. The drill bit assembly is then heated under atmospheric conditions. The steel tube is then hot pressed into the heated matrix and the drill bit assembly is allowed to cool before releasing the cooled drill bit from the mould.
