El ángulo de corte del taladro de giro ordinario estándar es 118, el ángulo de bisel del borde transversal es de 40 ° ~ 60 ° y el ángulo posterior es 8 ° ~ 20 °. Debido a las razones estructurales, el ángulo de rastrillo es grande en el borde exterior y disminuye gradualmente al medio, y el borde transversal es un ángulo de rastrillo negativo (hasta aproximadamente -55 °), que actúa como extrusión al perforar. Para mejorar el rendimiento de corte del taladro de giro, la parte de corte se puede moler en varias formas de acuerdo con las propiedades de los materiales procesados (como el taladro grupal).
La forma de vástago de perforación giratoria tiene dos tipos de vástago recto y cono, procesando el primer clip en el chuck de taladro, el último insertado en el huso de la máquina herramienta o el asiento de la cola del orificio del cono. El taladro de giro general está hecho de acero de alta velocidad. Inserte la cuchilla de carburo de soldadura o el taladro de torsión de la corona para el procesamiento de hierro fundido, acero endurecido y materiales no metálicos, como el taladro de giro pequeño de carburo cementado completo para el procesamiento de piezas de instrumentos y placas de circuito impresos.
