Abstract
"BROCA COM CABEçA DE CORTE SUBSTITUìVEL". A invenção refere-se a uma broca compreendendo um corpo da broca (1) uma peça postiça de corte (2) que está fixada ao corpo de broca de maneira removível e que forma a região do ponta da boca, e compreende uma ranhura para aparas (3) que continua até para dentro da peça postiça de corte (2). A dita peça postiça de corte se apoia com uma superfície de apoio (6), que se estende perpendicularmente em relação ao eixo longitudinal central (8) da broca, na superfície frontal (7) do corpo da broca (1), e extende-se com um pino de fixação (9), que se sobressai centralmente da superfície de apoio (6) para dentro de um recesso de recepção (1 0) configurado complementarmente a isso, e que é previsto na superfície frontal (7) do corpo da broca (1). Pelo menos um setor periférico (13) do pino de fixação (9) apresenta um primeiro setor longitudinal (15) que, com uma superfície helicoidal (1 6), que aponta para fora do corpo da broca (1), que ascende no sentido de rotação da broca em direção à ponta da broca (5), e que interage com uma contra-superfície (19) na parede interna (1 4) do recesso de recepção (10), se transforma em um segundo setor longitudinal (17).
