Abstract

trata-se de uma haste de ferramenta (20) que tem uma cavidade de recebimento de face (22) em uma extremidade anterior (24), e uma pluralidade de ranhuras de cavaco (26) que se estende para trás a partir da mesma ao longo de um eixo geométrico longitudinal (a1). a cavidade de recebimento de face tem uma superfície de sustentação (30) transversal ao eixo geométrico longitudinal. uma reentrância central (32) é formada na superfície de sustentação e se estende para trás a partir da mesma. a reentrância central tem uma pluralidade de porções contíguas deslocáveis de modo resiliente (38) que se alterna, de modo circunferencial, com e é distanciada por uma pluralidade de porções intermediárias (40). cada porção contígua tem uma superfície contígua voltada radialmente para dentro (42), e cada porção intermediária tem uma superfície intermediária (44) que cruza duas superfícies contíguas adjacentes de modo circunferencial. uma ferramenta de corte giratória inclui a haste e uma face de corte montada de modo removível no mesmo. a face de corte tem uma porção de montagem dotada de uma superfície de base e um membro de engate que se projeta a partir da mesma. em uma posição montada, o membro de engate é retido de modo resiliente na reentrância central contra a pluralidade de superfícies contíguas.
