V125 80° Stepped-Base Single-V Press Brake Lower Die – H120 × W154 mm, 100 Ton/m
This V125 80° stepped-base single-V press brake lower die features a 125 mm V-opening, 80° die angle, 120 mm overall height and 154 mm main body width, with a 90 mm bottom base width and 20 mm stepped mounting section. The rated load capacity is 100 ton/m. Unlike conventional plug-in single-V lower dies, this model uses a stepped-base mounting structure rather than a narrow plug-in shank. The V-opening, die angle, overall height, body width, base width, step geometry, groove radii, tooling length and mounting interface can all be customized according to the customer's press brake and bending requirements.

Description
V125 80° Stepped-Base Single-V Press Brake Lower Die
This V125 80° press brake lower die combines a very large single-V working groove with a stepped lower mounting structure, providing a robust lower-tool configuration for sheet metal bending applications that require substantial forming clearance and a large V-opening.
The illustrated configuration features:
V-Opening: V125 / 125 mm
Die Angle: 80°
Overall Height: 120 mm
Main Body Width: 154 mm
Bottom Base Width: 90 mm
Stepped Section Height: 20 mm
Shoulder Radius: R12
V-Bottom Radius: R15
Rated Load Capacity: 100 ton/m
The lower mounting profile is structurally different from the narrow plug-in mounting structure used on many standard single-V lower dies. In this design, the wide 154 mm body transitions to a 90 mm stepped bottom base, forming a broader mounting profile for compatible lower-die holders and press brake systems.
The tooling shown represents one available configuration only. WYS Machinery can manufacture different V-openings, angles, heights, widths, radii and mounting profiles according to customer requirements.
V125 Opening for Very Large Forming Clearance
The 125 mm V-opening provides a very large working zone and substantial clearance around the workpiece during bending.
Compared with smaller V-opening dies, the V125 configuration is suitable for applications requiring:
- Very large V-opening air bending
- Greater workpiece clearance
- Larger expected inside bend radii
- Broader flange and sheet geometry
- Large-section forming applications
- More space around the sheet during bending
The correct V-opening should always be selected according to the material grade, sheet thickness, required inside radius, minimum flange dimension and required bending force.
80° V-Groove for Custom-Angle Air Bending
The illustrated lower die uses an 80° single-V groove.
Compared with wider-angle lower dies such as 85°, 88° or 90°, the 80° geometry provides additional angular clearance and can be used in applications where a more acute lower-die angle is required.
The final bending result depends on factors including:
- Material grade
- Sheet thickness
- Punch geometry
- V-opening
- Material springback
- Required inside bend radius
- Flange dimensions
- Required bending force
The illustrated 80° groove is one available configuration only. Different die angles can also be manufactured according to the customer's forming requirements.
Stepped-Base Mounting Structure
A key feature of this lower die is its stepped-base mounting profile.
The illustrated structure includes:
Main Body Width: 154 mm
Bottom Base Width: 90 mm
Step Height: 20 mm
This differs from a plug-in lower die, which normally uses a narrower bottom mounting shank beneath the main tool body.
The stepped-base design combines a wide main working body with a narrower supporting base and can be adapted according to the customer's lower-die holder, machine interface and existing tooling arrangement.
The base width, step height, body width, positioning geometry and complete die cross-section can all be customized.
R12 Shoulder Radius and R15 V-Bottom Radius
The illustrated V125 lower die includes two clearly defined radius features:
Shoulder Radius: R12
V-Bottom Radius: R15
These radii form part of the working profile and can also be customized according to the V-opening, material, sheet thickness and required bending geometry.

Customers can provide a machine model, existing lower-die drawing, die-holder dimensions, tooling cross-section, tooling sample or workpiece drawing for technical evaluation.
Custom V-Opening and Die Angle
The V125 opening and 80° groove shown here are one available specification rather than fixed limitations.

- Material grade
- Sheet thickness
- Required bending angle
- Desired inside radius
- Minimum flange dimension
- Material springback
- Required forming clearance
- Required bending force
