Function Description:
- Punch is designed with oil groove, to reduce the wearing of the guide.
- Inner side of die is designed as circular arc, load bearing strength of the blade better, increase the service life.
- No slug die design as cutting edge concave emboss, eliminate slug pulling and floating.
- Guide surface with lubrication groove design, graphite processing to reduce the wearing of the machine's turret holes.
- Punch surface can be produced as rooftop or whisper type, please inform when you order.
- Rooftop angle is2°; Whisper angle is 5°.
