Application
Can be used with a ball bearing screw for manual operation using a wrench, or with a tension bolt for operation using hydraulic equipment.
Pre-drill sheets as follows:
Screw dia. 6.0 mm = 6.2-6.5 mm hole
Screw dia. 9.5 mm = 9.7-10.0 mm hole
Screw dia. 19.0 mm = 19.5-20.0 mm hole
Max. carbon steel ST37 sheet thickness up to 2 mm.

Execution

• Hole puncher with splitting punch that divides the waste piece into three equal-sized pieces
• The hole puncher consists of three pieces: the die, the stamp and a ball bearing connecting screw

Advantage
Das Abfallstück zerfällt in drei Teile und verkantet deshalb nicht mehr in der Matrize – für gratfreie Ausstanzungen.

Notes
