Description
The WYS 85° Bystronic-type large-clearance gooseneck punch is designed for complex sheet-metal components that may interfere with a conventional straight upper tool.
Its deeply recessed gooseneck profile provides substantial clearance for return flanges, tall sidewalls and previously formed sections. The 250 mm overall height also provides extended working reach for deep boxes, cabinets, enclosures and other high-profile workpieces.
The punch has a 10 mm wide working tip with an R1 radius. Compared with a larger R3 tip, the smaller R1 radius is better suited to applications requiring a tighter bend line, subject to the material’s minimum permissible bend radius and the selected lower-die opening.

Tooling Selection and Customization
The R1 tip can support a tighter bend line than an R3 punch, but the final inside radius also depends on the material grade, sheet thickness, lower-die opening and forming method. Material minimum-radius requirements must be checked to reduce the risk of cracking.
WYS can customize the punch height, width, gooseneck clearance, working angle, tip width, tip radius, mounting interface, tooling length and segmentation according to the customer’s workpiece and press brake.
Customers can provide their finished-part drawings, material information, bending length and machine specifications. Our engineering team can evaluate flange clearance, bending sequence, V-opening, required radius and forming force before recommending a suitable tooling solution.
The stated 90 ton/m is the maximum rated load of the punch. Actual working force must remain within the permissible capacity of every component in the complete tooling setup.
This product is manufactured by WYS for compatible Bystronic-type tooling systems. WYS is an independent press brake tooling manufacturer, and no official affiliation with the referenced machine brand is implied.
