Abstract

inserto de perfuração indexável e ferramenta de corte rotativa. um inserto de perfuração (20) tem uma porção central (22) com um eixo central (ac) e três porções de ponta espaçadas circunferencialmente (24a, 24b, 24c). cada porção de ponta tem um primeiro eixo (ai) e duas primeiras arestas de corte divergentes (30a, 30b) com pontos de corte radialmente mais externos (nc1, nc2) definindo um primeiro círculo situado em um plano de ponta perpendicular ao primeiro eixo e tendo um primeiro diâmetro de corte. em uma vista ao longo de um dos primeiros eixos, um segundo círculo tendo um segundo diâmetro circunscreve o inserto de perfuração e o primeiro diâmetro de corte é pelo menos sessenta por cento do segundo diâmetro. uma ferramenta de corte rotatória em torno de um eixo de ferramenta com um diâmetro de corte de ferramenta inclui o inserto de perfuração (20) e um segundo inserto de corte tendo uma segunda aresta de corte. uma das porções de ponta é operativa tendo seu primeiro eixo coaxial ao eixo da ferramenta e a segunda aresta de corte se estende radialmente para fora do primeiro diâmetro de corte.
