Thread chaser tool for contiguous straight and tapered thread runs |
摘要 |
A thread chaser tool with cutting edge defined by two symetrical points. The tip radii of the two points are spaced apart slightly less than the pitch of a thread to be cut. The thread form is generated by the inside flanks of each point and a crestforming radius there between. Both points cooperate in forming the long flanks of either male or female tapered threads, and both points form straight threads having two roots.
