Description
The TRUMPF Type Size I SQ20 Square Punch & Die Tooling is manufactured for precision square-hole punching in sheet metal fabrication applications using TRUMPF-style Size I tooling systems.
The tooling shown on this page includes an SQ20 square punching profile manufactured as a representative sample of our punching tooling capability. In the tooling designation, SQ represents a square profile, while 20 indicates a nominal side dimension of 20 mm. The resulting nominal punching profile is therefore 20 × 20 mm.
The SQ20 specification is an example rather than a fixed limitation. We can manufacture TRUMPF Type square punch tooling in different dimensions, together with corresponding lower dies and application-specific die clearances.
In addition to square punching tools, round, rectangular, obround and complex special-shaped tooling can also be manufactured according to customer drawings and sheet metal processing requirements.

What Does SQ20 Mean?
SQ20 is the tooling designation used for the square punching profile shown on this page.
SQ represents a square profile, while 20 indicates a nominal side length of 20 mm.
Therefore:
- Shape: Square
- Width: 20 mm
- Length: 20 mm
- Nominal Profile: 20 × 20 mm
The SQ20 size shown here is only a production sample. Other square dimensions can be manufactured according to the required hole size and sheet metal component design.
Square Punch Tooling for Sheet Metal
Square holes are widely used in fabricated sheet metal components where a conventional round hole cannot provide the required mounting, assembly or functional geometry.
During punching, the square punch and corresponding lower die work together to shear the sheet along four straight cutting edges and form the required square opening.
Accurate machining of the punch profile and die opening is particularly important for square tooling because the straight edges and four corners must work consistently throughout the punching process.
Our TRUMPF Type square punch tooling can be manufactured for different square dimensions according to customer requirements.
Punch and Lower Die Configuration
A complete punching application requires the punch and lower die to work as a matched tooling system.
The punch determines the required punching profile, while the lower die provides the corresponding opening and clearance necessary for material shearing.
For custom SQ punch tooling, customers can provide:
- Required square-hole dimensions
- Sheet material
- Sheet thickness
- Existing punch specification
- Required die clearance
- Workpiece drawing
Based on these parameters, the corresponding punch and lower die can be manufactured for the application.
Custom Die Clearance
The required die clearance depends on factors such as sheet material and material thickness.
For this reason, even when two applications both require an SQ20 square hole, their lower dies may require different clearance specifications.
We can manufacture lower dies with application-specific clearance according to customer requirements. This allows the tooling configuration to better match different sheet metal punching conditions.
Custom Square Punch Sizes
The 20 × 20 mm SQ20 profile is not the only available square size.
Different square punching dimensions can be manufactured according to customer requirements. Customers can specify the required side length directly or provide a component drawing for tooling design.
This makes custom square punch tooling suitable for different hole dimensions used in:
- Mounting features
- Electrical components
- Panel openings
- Mechanical connections
- Sheet metal assemblies
- Equipment housings
- Custom fabricated parts
Standard & Custom Punching Profiles
Our TRUMPF Type Size I tooling capability extends beyond square holes.
Available punching profiles include:
- SQ – Square
- RO – Round
- RE – Rectangle
- OB – Obround / Oblong
- Slot profiles
- Polygonal profiles
- Keyhole-type profiles
- Notching profiles
- Irregular contours
- Special-shaped punching profiles
For non-standard applications, customers can provide a DXF, CAD drawing or finished-part drawing. Custom punch and die tooling can then be manufactured according to the actual geometry of the sheet metal component.
Typical Applications
TRUMPF Type Size I square punch tooling can be used in the production of:
- Electrical cabinets and switchgear
- Control panels
- Sheet metal enclosures
- Machinery covers and guards
- Equipment housings
- Metal cabinets
- HVAC components
- Mounting plates
- Brackets and structural sheet metal parts
- Automotive sheet metal components
- Industrial equipment panels
- Custom fabricated metal products
The SQ20 20 × 20 mm square punch shown on this page is particularly suitable for components requiring a precise square opening, while other dimensions can be manufactured for different sheet metal designs.
Custom TRUMPF Punch Tooling from Your Drawing
The SQ20 tooling displayed here demonstrates only one configuration within our custom TRUMPF Type punch tooling capability.
Customers are not limited to the shape or dimensions shown in the photographs.
Simply provide the required hole dimensions or send us your DXF, CAD or finished workpiece drawing, together with the sheet material and thickness. We can manufacture the corresponding punch and lower die according to the required profile, dimensions and die clearance.
From conventional square, round, rectangular and obround tooling to complex special-shaped profiles, customized punch tooling solutions are available for different sheet metal punching applications.
