Abstract

"PONTA CORTANTE DE BROCA". A presente invenção se refere a uma ponta cortante de broca (1) para trabalho em metal, ponta cortante de broca que possui uma ponta central (2) que passa dentro das bordas de corte (3) se estendendo na direção da periferia, e uma linha central (A). A ponta cortante de broca (1) possui um ângulo de corte (<244>) de 1<198> - 20<198> entre a direção normal do eixo geométrico de broca e uma borda de corte (3) que assim está inclinada na direção da linha central (A). A ponta central (2) forma um ângulo de afinação de ponto (<sym>) de 90<198> <sym> 2<198> e uma base que ocupa até 23 % - 45 %, ou preferivelmente 30 % - 40 %, e o mais preferivelmente cerca de um terço do diâmetro total da ponta cortante de broca (1). A ponta cortante de broca (1) possui um ângulo de ponta (<225>) de 90<198> <sym> 10<198>.
