Abstract

<B>"BROCA DE CORTE DE METAL COM INSERçãO APRESENTANDO BORDAS DE CORTE QUE SE SOBREPõEM RADIALMENTE"<D>. A presente invenção trata de uma broca de corte de metal, que inclui um corpo de broca de aço e uma inserção de carbeto soldada ao mesmo. O corpo de broca inclui uma face frontal, tendo um rebaixamento formado na mesma, o rebaixamento se sobrepondo radialmente a um eixo longitudinal do corpo de broca. A inserção é soldada no rebaixamento e inclui uma pluralidade de bordas de corte espaçadas, expostas em lados opostos do eixo. As bordas de corte se sobrepõem radialmente durante uma operação de perfuração. Uma das bordas de corte se projeta radialmente, internamente, além de uma face lateral de cabeçote, e uma outra das bordas de corte termina radialmente, internamente à face lateral.
