Abstract
uma broca de perfuração que inclui um corpo de broca possui uma ou mais lâminas que se estendem deste e uma pluralidade de cortadores afixados a uma ou mais lâminas. um ou mais elementos rotativos são posicionados sobre o corpo de broca, cada elemento rotativo tendo uma porção de rolamento cilíndrica que define um eixo de rotação. cada elemento rotativo está acoplado rotativamente ao corpo da broca em torno do eixo de rotação dentro de um bolso correspondente definido no corpo da broca e um pino de travamento fixa o elemento rotativo no interior do bolso. uma ou mais superfícies de apoio internas do bolso engatam a porção de rolamento cilíndrica e o bolso circunda parcialmente a porção de rolamento cilíndrica, deixando um comprimento do elemento rotativo exposto.
