Abstract

broca problema: fornecer uma broca que capacite uma grande redução em resistência ao corte e fácil execução de uma operação em resistência ao corte e fácil execução de uma operação de furação por meio de força humana usando uma furadeira manual, uma máquina de furar ou coisa parecida. solução: uma broca tem duas bordas de corte formadas simetricamente com relação a um eixo de rotação, e é submetida a adelgaçamento na ponta da mesma. a borda de corte é configurada de uma borda de corte adelgaçada (1) que se estende em uma forma incluindo uma linha curva de uma borda de cinzel para o lado periférico externo da broca, e uma borda de corte principal (2) que se estende em uma forma incluindo uma linha curva de uma borda de cinzel para o lado periférico externo da broca, e uma borda de corte principal (2) que se estende da extremidade da borda de corte adelgaçada para a extremidade periférica externa da broca quando vista pelo lado de ponta da broca, e uma superfície adelgaçada formada pela borda de corte adelgaçada é concretizada em uma forma aproximadamente parabólica inclinada em uma direção de eixo geométrico de broca quando vista pelo lado dianteiro da broca.
