V64 85° Stepped-Base Single-V Press Brake Lower Die – H75 × W80 mm, 100 Ton/m
This V64 85° stepped-base single-V press brake lower die features a 64 mm V-opening, 85° die angle, 75 mm overall height and 80 mm main body width, with a 60 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 configuration uses a stepped-base mounting structure rather than a narrow plug-in shank. The V-opening, die angle, overall height, body width, base dimensions, groove radius, tool length and mounting interface can all be customized according to the customer's press brake and bending requirements.

Description
V64 85° Stepped-Base Single-V Press Brake Lower Die
This V64 85° press brake lower die uses a single-V working groove combined with a stepped lower mounting structure, providing a stable lower-tool configuration for larger V-opening sheet metal bending applications.
The illustrated model features:
V-Opening: V64 / 64 mm
Die Angle: 85°
Overall Height: 75 mm
Main Body Width: 80 mm
Bottom Base Width: 60 mm
Stepped Section Height: 20 mm
Groove Shoulder Radius: R3
V-Bottom Radius: R8
Rated Load Capacity: 100 ton/m
The lower mounting profile is structurally different from the narrow plug-in mounting configuration used on many other single-V dies. Its 80 mm upper body transitions to a 60 mm wide stepped base, creating a distinct mounting geometry for compatible lower-die holders and machine arrangements.
The dimensions shown represent one available configuration only. WYS Machinery can manufacture different die cross-sections according to the customer's machine, tooling holder and workpiece requirements.
V64 Opening for Large Forming Clearance
The 64 mm V-opening provides a large working zone for sheet metal bending.
Compared with smaller V32, V40 and V50 lower dies, the V64 opening provides additional forming clearance and is suitable for applications requiring:
- A larger forming space
- A larger expected inside bend radius
- Greater workpiece clearance
- Wider flange and sheet geometry
- Larger V-opening air-bending applications
The correct V-opening should always be selected according to the material grade, sheet thickness, desired bend radius, minimum flange size and required bending force.
85° V-Groove for Precision Air Bending
The illustrated lower die uses an 85° V-groove, suitable for precision air-bending applications where additional angular allowance may be required to compensate for springback.
The actual final bend angle depends on several factors, including:
- Material type
- Sheet thickness
- Punch angle
- V-opening
- Material springback
- Inside bend radius
- Flange dimensions
- Bending force
The 85° configuration is not a fixed limitation. 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 structure.
The illustrated geometry includes:
Main Body Width: 80 mm
Bottom Base Width: 60 mm
Stepped Section Height: 20 mm
This differs from a typical plug-in lower die, which normally uses a narrow mounting shank beneath the main tool body.
The stepped-base structure provides a broader and more substantial mounting profile and can be adapted according to the lower-die holder or machine interface.
The base width, step height, body width and positioning geometry can all be customized.
R3 Shoulder Radius and R8 V-Bottom Radius
The illustrated V64 groove includes two clearly defined radius features:
Shoulder Radius: R3
V-Bottom Radius: R8
These radii influence the geometry around the working groove and can be modified when different forming conditions require alternative edge or bottom-radius geometry.
The groove radii are not limited to the values shown.

- Material grade
- Sheet thickness
- Required bending angle
- Desired inside radius
- Minimum flange dimension
- Material springback
- Required forming clearance
- Required bending force
- Press brake configuration
This allows the tooling geometry to be designed around the customer's actual workpiece rather than limiting the application to one standard lower die.
