Abstract

UM ENCAIXE DE BROCA INDEXÁVEL. A invenção diz respeito a um encaixe de broca quadrangular indexável compreendendo uma superfície superior, uma superfície inferior, e uma superfície lateral adjacente às superfícies superior e inferior substancialmente planas. Quator arestas de corte são configuradas na intersecção das superfícies do lado, e superior. Cada aresta de corte compreende uma aresta de primeira peça, uma aresta de segunda peça que se estende desde a aresta da primeira peça, e uma aresta de terceira peça que se estende para longe do eixo do encaixe. As arestas da segunda peça e da terceira peça são unidas por uma aresta da peça de transição. A aresta da peça de transição faz um ângulo que varia de 10º a 90º em relação ao plano de referência horizontal. Além disso, a referida aresta da peça de transição faz uma curva convexa com a aresta da segunda peça e uma curva côncava com a aresta da terceira peça. Uma porção de ponta é fornecida nos quatro cantos do encaixe de broca.
