What Are V Dies? Definition, Mechanics, and Applications
Understand how single V dies function as the foundation of modern press brake forming—delivering predictable tonnage demand, precise angle control, and dependable batch consistency.
How V Dies Shape Sheet Metal
A V die is a standard bottom press brake tool featuring a precision-machined V-groove. As the upper punch drives the metal sheet into the groove, the V-opening width directly dictates the bend radius, springback behavior, and required machine tonnage.
Air Bending Versatility
The punch forces material into the V-opening without contacting the bottom. This allows operators to form multiple bend angles using a single setup by simply adjusting stroke depth.
Bottoming for High Accuracy
The sheet metal is pressed fully against the V-die sidewalls, virtually eliminating springback and ensuring exact angular consistency across high-volume production runs.
Why Choose CAMT V Dies?

V-Opening Selection & Machine Compatibility Guidelines
Optimize sheet metal bending accuracy, control required tonnage, and match your machine style with precise V-die sizing rules and press brake tooling material guide recommendations.
Standard Air Bending Rule
For mild steel, select a V-opening equal to 8 times the material thickness (V = 8 × T) to achieve predictable springback and optimal bend radii.
Thin Sheet & Narrow Flanges
Use a 6x material thickness V-opening (V = 6 × T) when forming short minimum flange lengths or working with light-gauge sheet metal.
Heavy Plate & Stainless Steel
For high-tensile stainless or heavy plate over 6 mm, select 10x to 12x thickness to reduce bending force and protect die shoulders from wear.
Essential V-Die Parameters
- V-Width (V): The top opening dimension that directly determines required tonnage and internal bend radius.
- Minimum Flange (b): The shortest leg length supported across the shoulder radii without slipping into the V-groove.
- Internal Radius (R): Calculated at approximately 16% of the V-opening width during standard air bending operations.

| 0.8 – 1.0 mm | 6 – 8 mm | 1.0 mm | 4.5 mm |
| 1.2 – 1.5 mm | 8 – 10 mm | 1.5 mm | 6.0 mm |
