Metallic Rittal AS 4055.774 matrix for 11.5 mm round punches — spare part

Rittal AS 4055.774 metallic matrix is a spare part intended for use with 11.5 mm round punches in Rittal punching systems. The matrix provides the cutting profile required to produce clean, uniform round holes in metal panels and busbars. Designed for compatibility with the appropriate male die, it is used where precise 11.5 mm circular openings are necessary in electrical enclosures, control cabinets and related sheet metal applications.

Advantages

The metallic construction ensures durability and consistent hole quality over repeated cycles. When combined with the matching male die, the matrix forms precise 11.5 mm round holes with minimal burr and reliable repeatability. Its design is focused on professional cabinet and enclosure fabrication workflows, supporting efficient punching operations and reducing the need for secondary finishing.

Suitable for

• Punching 11.5 mm round holes in electrical enclosures and control cabinets
• Creating openings in busbars when used together with the corresponding male die
• Sheet metal fabrication tasks requiring consistent circular holes of 11.5 mm diameter
• Replacement or spare-part use in Rittal punching systems to maintain production uptime

When it may not be suitable

This matrix is specifically sized for 11.5 mm round holes and will not produce other diameters or hole shapes. It must be used together with the compatible male die; using it alone or with incompatible tooling may cause poor results or damage. For non-metal materials, very thick material stacks, or non-round hole requirements, alternative tooling or machining methods should be considered.

Key specifications

• Hole shape: round
• Hole diameter: 11.5 mm
• Material: metallic matrix suitable for punching operations
• Application: designed for use with matching male die to punch busbars and sheet metal panels
• Compatibility: intended for Rittal punching systems and standard male dies of corresponding geometry

How to use

Install the matrix into the punch press or Rittal punching system following the machine manufacturer’s instructions. Fit the corresponding male die that matches the matrix profile, align the workpiece so the intended hole positions correspond to the tooling, and perform punching operations at recommended press settings. Inspect punched holes for correct diameter and edge quality; replace the matrix if wear affects hole quality.

What to consider before purchase

• Confirm the required hole diameter is 11.5 mm and that round holes meet your application needs
• Verify compatibility with your Rittal punching system and availability of the matching male die
• Assess material type and thickness to ensure the matrix is suitable for the intended workpiece
• Plan for periodic inspection and replacement based on production volume and wear

Usage recommendations

Use the metallic matrix together with the correct male die and operate within the machine’s specified press capacities. Regularly inspect tooling for wear, maintain alignment during setup, and perform test punches on scrap material to confirm settings before production runs.
