Punch and extruder Biroskop 4 mm
Biroskop HC4 is a double-sided stainless steel cutter for making clean 4mm holes. It can also be used as a miniature extruder for creating thin clay coils.
- precise cutting with minimal residue
- lightweight, double-sided design that rotates comfortably between your fingers
- cutter and extruder in one tool
When using the extruder function, it is best to use soft, well-conditioned clay, as the small diameter requires greater material plasticity.
