Abstract

Las implementaciones incluyen herramientas de perforación que tienen vías de agua ahusadas axialmente que pueden aumentar la limpieza y la vida útil de la broca, en tanto que, además, reducen la obstrucción. La herramienta de perforación puede tener una muesca única que se extiende dentro de la cara cortante y una pluralidad de pozos que se extienden desde la cara cortante hasta un espacio interno de la herramienta de perforación. Las implementaciones incluyen, además, sistemas de perforación que incluyen herramientas de perforación que tienen una muesca única y una pluralidad de pozos.The implementations include drilling tools that have axially tapered waterways that can increase the cleanliness and lifespan of the drill, while also reducing clogging. The drilling tool may have a single notch that extends into the cutting face and a plurality of wells that extend from the cutting face to an internal space of the drilling tool. The implementations also include drilling systems that include drilling tools that have a single notch and a plurality of wells.
