Press brake tooling plays a critical role in sheet metal bending performance. Although the press brake machine provides the bending force, the tooling determines the final bending accuracy, surface quality, production efficiency, and tool life.
For manufacturers working with different materials, thicknesses, and bending requirements, choosing the correct press brake tooling is essential.
This complete press brake tooling guide explains everything you need to know about:
Different types of press brake tooling
Tool steel materials and hardness
How to select the right punches and dies
Compatibility with major press brake brands
Tool maintenance methods to extend service life
Press brake tooling refers to the upper and lower tools installed on a press brake machine to form sheet metal into specific angles and shapes.
The main components include:
Press brake punches (upper tools)
Press brake dies (lower tools)
V dies
Special forming tools
Quick clamping tooling systems
Unlike the press brake machine itself, tooling directly contacts the metal sheet. Therefore, tooling quality has a significant impact on:
Bending accuracy
Surface marks
Production efficiency
Tool replacement frequency
Choosing the right tooling type depends on bending method, material thickness, machine configuration, and production requirements.
Punch Type | Profile / Feature | Best For | Main Advantage |
Straight Punch | Straight body with standard tip | General 90° bending | Versatile and easy to use |
Gooseneck Punch | Recessed / offset body | Deep boxes, return flanges | Avoids interference with formed flanges |
Sash Punch | Narrow, offset profile | Window frames, channels, narrow profiles | Better clearance for complex profiles |
Acute Angle Punch | Sharp-angle tip, typically below 90° | Acute bends, pre-bending, hemming preparation | Suitable for small-angle and precision forming |
Radius Punch | Larger nose radius | Large-radius bending | Reduces concentrated stress and helps control bend radius |
Hemming Punch | Flat / specialized forming profile | Closed hems and reinforced edges | Creates safer, stronger finished edges |
Tip: The correct punch should be selected according to flange geometry, bend angle, inside radius, material thickness and available clearance—not simply by punch shape.

Selecting tooling requires considering several factors.
The thicker the sheet metal, the larger the required V opening.
Example:
Thin sheet:
1-3mm
↓
Small V opening
Medium plate:
3-8mm
↓
Medium V opening
Heavy plate:
Large V opening
