Description
T-Type 85° Single-V Press Brake Lower Die with 60 mm Wide Base
This T-type single-V press brake lower die combines a wide supporting base with a vertical single-V working section, providing a stable lower-tool structure for sheet metal bending applications.
The illustrated configuration has an 80 mm overall height, and its effective working height is also 80 mm. The bottom base is 60 mm wide and 18 mm high, while the rated load capacity is 100 ton/m.
The upper working section uses an 85° single-V groove. Different V-openings, load-bearing widths and V-groove radii are available, allowing the same T-type structure to be adapted to different material thicknesses, bend radii and forming requirements.
The dimensions shown represent available configurations rather than fixed limitations. WYS Machinery can manufacture the complete die cross-section according to the customer's press brake and workpiece requirements.
85° Single-V Groove for Precision Air Bending
The illustrated lower die uses an 85° V-groove, making it suitable for air-bending applications where additional angular allowance may be required before the material springs back toward the final bend angle.
The final bending result depends on factors such as:
- Material grade
- Sheet thickness
- V-opening
- Punch angle
- Material springback
- Required inside bend radius
- Minimum flange dimension
- Bending force
For this reason, the 85° geometry is not the only available configuration. The die angle can also be customized according to the actual forming process.
Wide T-Shaped Base Structure
The 60 mm wide T-shaped base is one of the key structural characteristics of this lower die.
Compared with a narrow straight-body lower die, the wide base provides a broader supporting platform beneath the vertical working section.
This type of structure can be manufactured for applications requiring:
- A wider lower-tool supporting surface
- Different die-holder configurations
- Customized positioning geometry
- Alternative lower-die mounting interfaces
- Special machine or tooling arrangements
The base width and mounting profile can also be modified according to customer requirements.
Custom V-Opening, Load-Bearing Width and V-Groove Radius
Three important dimensions can be selected or customized on this lower die:
V – V-Opening
The opening width of the bending groove.
S – Load-Bearing Section Width
The width of the main supporting section beneath the V-groove.
R – V-Groove Radius / Edge Radius
The radius geometry around the V-groove.
These dimensions can be selected from the standard combinations below or manufactured according to the customer's actual workpiece requirements.
Available T-Type Lower Die Specifications
| Model | V-Opening V (mm) | Radius R (mm) | Load-Bearing Width S (mm) | Max. Capacity (t/m) |
|---|---|---|---|---|
| T6 | 6 | 0.4 | 14 | 100 |
| T8 | 8 | 0.5 | 14 | 100 |
| T10 | 10 | 0.8 | 18 | 100 |
| T12 | 12 | 2.75 | 18 | 100 |
| T16 | 16 | 2.75 | 24 | 100 |
| T20 | 20 | 3 | 30 | 100 |
| T25 | 25 | 3 | 35 | 100 |
| TR6 | 6 | 2.75 | 14 | 100 |
| TR8 | 8 | 2.75 | 14 | 100 |
| TR10 | 10 | 2.75 | 18 | 100 |
These values represent available standard configurations. Non-standard V-openings, radii and load-bearing widths can also be manufactured according to customer requirements.
T-Series and TR-Series Groove Options
The standard specification range includes both T-series and TR-series configurations.
The T6, T8 and T10 versions use smaller groove radii:
T6 – R0.4
T8 – R0.5
T10 – R0.8
The corresponding TR configurations use a larger R2.75 radius:
TR6 – R2.75
TR8 – R2.75
TR10 – R2.75
This gives customers additional groove-radius options while retaining the T-type wide-base lower-die structure.
Overall Height Equals Effective Height
For the illustrated configuration:
Overall Height: 80 mm
Effective Height: 80 mm
The tool height can also be customized according to the customer's machine and tooling combination.
Different effective heights may be required to match:
- Existing press brake punches
- Existing lower tooling
- Machine daylight
- Clamping systems
- Required bending centerline
- Customer-specific tooling arrangements

Available configurations include:
TRUMPF Type, WILA Type, LVD Type, Bystronic Type, Amada / Promecam Type, European Type and other customized press brake tooling systems.
The T-shaped structure illustrated on this page is only one available configuration.
The bottom mounting profile, locating geometry, base structure, effective height and complete tooling cross-section can all be adapted according to the customer's press brake.
Customers can provide a machine model, existing tooling drawing, lower-die cross-section, die-holder dimensions, tooling sample or workpiece drawing for technical evaluation.
Custom V-Opening and Die Angle
The standard specification table includes V6, V8, V10, V12, V16, V20 and V25, but customers are not limited to these sizes.
Different V-openings can be manufactured according to:
- Sheet thickness
- Material grade
- Required bend angle
- Required inside radius
- Minimum flange dimension
- Springback characteristics
- Required forming clearance
- Bending force
- Machine configuration
The 85° groove angle can also be changed when another angle is more suitable for the customer's bending process.
Custom Load-Bearing Width and V-Groove Radius
The load-bearing width S and radius R can be customized together with the V-opening.
This allows the complete working profile of the die to be designed around the required bending process rather than forcing the customer to use one fixed standard geometry.
For special bending applications, WYS Machinery can manufacture the lower die according to a customer drawing or design a suitable tooling cross-section based on the finished workpiece.
Custom Press Brake Tooling Design Service
Customers can provide:
workpiece drawings, material grade, sheet thickness, required bend angle, desired inside radius, existing tooling information and press brake model.
Our engineering team can evaluate the bending requirement and recommend a suitable tooling configuration.
The lower die can then be manufactured with the required V-opening, angle, height, base width, load-bearing width, radius, length and mounting structure.
