Abstract

uma ferramenta de corte rotativa tendo um corpo de ferramenta que pode ser inserido em uma coluna de perfuração com uma pluralidade de conjuntos de cortador que podem ser projetados ou que podem ser estendidos em posições distribuídas azimutalmente ao redor do eixo longitudinal do corpo da ferramenta. cada conjunto de cortador inclui uma estrutura de suporte com uma pluralidade de cortadores com as superfícies de corte duras expostas voltadas em uma direção de rotação da ferramenta. a estrutura de suporte pode ter uma superfície posicionada para estar em contato com uma parede do duto e pode ser feita como um corpo de material particulado infiltrado com um ligante metálico, onde o material particulado pode incluir materiais como carboneto de tungstênio com uma dureza knoop de pelo menos 1000. a estrutura de suporte pode ter uma composição funcionalmente granulada com material duro para estar em contato com a parede e o aço em uma região que será usinada durante a fabricação.a rotary cutting tool having a tool body that can be inserted into a drill string with a plurality of projectable cutter assemblies or that can be extended in azimuthally distributed positions about the longitudinal axis of the tool body. each cutter assembly includes a support structure with a plurality of cutters with exposed hard cutting surfaces facing in a rotational direction of the tool. the support structure may have a surface positioned to be in contact with a duct wall and may be made as a body of particulate material infiltrated with a metal binder, where the particulate material may include materials such as tungsten carbide with a knoop hardness of at least 1000. the support structure may be functionally granulated with hard material to be in contact with the wall and steel in a region that will be machined during fabrication.
