ЧТО ОЗНАЧАЕТ СЛОВО TWIST DRILL
Сверло
Буровые долота - это режущие инструменты, используемые для создания цилиндрических отверстий, почти всегда круглого поперечного сечения. Буровые долота бывают разных размеров и имеют много применений. Биты удерживаются в инструменте под названием сверло, которое вращает их и обеспечивает крутящий момент и осевое усилие для создания отверстия. Специализированные биты также доступны для отверстий без цилиндрической формы. Хвостовик является частью бурового долота, захваченного патроном сверла. Режущие кромки бурового долота находятся на одном конце, а хвостовик - на другом. Буровые долота выпускаются в стандартных размерах, описанных в изделии для сверла. В полноразмерной диаграмме сверла и размерах кранов указаны сверла с метрическими и имперскими размерами рядом с требуемыми размерами резьбовых соединений. Термин дрель может относиться либо к буровому станку, либо к буровому долоту для использования в бурильной машине. В этой статье для большей ясности сверло или бит используются повсюду, чтобы ссылаться на бит для использования в сверлильном станке, а сверло всегда относится к буровой машине. Исключительно, биты специальной формы могут разрезать отверстия некруглого поперечного сечения; возможно квадратное поперечное сечение.
