- form B closed
- with spiral point
- cone 1:16
- for threads and sealants
Use:
For manual and machine use, to machine steel up to about 800 N/mm² and diverse materials.
The spiral point causes a free flow of the chips forward and a reduction in the average torque. Chip clogging in the holes is avoided. An improved surface quality in the cut threads and longer service life is achieved. All dies used on machines must therefore be equipped with a spiral point.
