140320 JBO, HSS Whitworth pipe thread

Die JBO, HSS Whitworth pipe thread

- Form B closed

- with spiral cut

- tolerance field A

Use:

For manual and machine use, for machining steel up to approx. 800 N/mm² and a wide variety of materials. The spiral cut allows the chips to flow freely forwards and reduces the cutting torque. Chip build-up in the chip holes is avoided. This results in an improved surface quality of the cut threads and a longer service life. All dies used on machines must therefore be equipped with a spiral cut.
