Description

конусные поверхности исключают затирание по задним поверхност м при реверсировании. Попеременна  работа лезвий с левым и правым вращением повышает суммарную стойкость по сравнению со сверлами однонаправленного резани . При реверсировании с высокой частотой и малой угловой амплитудой возможна безинерционна  работа в невесомости .tapered surfaces eliminate rubbing on the back surfaces when reversing. Alternating blade operation with left and right rotation increases overall durability compared to unidirectional drill bits. When reversing with high frequency and low angular amplitude, no inertia operation is possible in weightlessness.
