Pot broach

摘要

A tooth broach designed for use with thin workpieces having its teeth arranged in circumferentially extending sets in each of which the teeth are arranged in groups of one or more teeth, and gaps devoid of teeth between adjacent groups. The teeth are further arranged in longitudinally extending series, in which consecutive teeth in each series are separated by gaps in the adjacent sets. This provides for reduced axial spacing between axially adjacent sets of teeth to maintain cutting action at all times with a thin workpiece.
