Interrupted thread taper pipe taps always have an odd number of flutes to insure continuous engagement. Every other tooth is removed on each cutting edge to allow heavier chips to flush without packing while the tap is engaged.
Features:
- Produces threads which conform to the American National Standard Taper Pipe Thread dimensions
- Interrupted threads reduce friction and permit better lubrication
- To lessen the damaging effects of chip wedging on both forward and reverse rotation interrupted thread taps are a solution. They reduce friction, permit better lubrication and allow more space for the passage of chips. The chamfered portion is left with full threads to assist in accurate engagement on the start.
