## Long description

Rittal AS 4055.771 metallic accessory — Matrize 9.0 mm, round is a precision female die designed for use with compatible Rittal tooling where a 9.0 mm round die is required. Supplied in a metallic finish and weighing approximately 326 g per package, this component is intended to be paired with the corresponding male die to form or crimp round holes in conductive materials such as busbars. The part supports accurate hole geometry and consistent results when integrated into the appropriate die set and press or punching equipment.
Advantages
The female die provides consistent 9.0 mm round hole dimensions and is manufactured to fit Rittal-compatible tooling. Its metallic construction offers durability for repeated forming or punching cycles and stable alignment when used together with the matched male die. The compact weight and standard geometry make it suitable for controlled punching in assembly and electrical fabrication workflows.
Suitable for
 Punching round holes in busbars and flat conductive strips
 Use in Rittal-compatible presses, punching tools or die sets
 Metalworking tasks requiring a 9.0 mm round female die for forming or crimping
 Replacement or spare part for existing die sets that accept 9.0 mm round matrizes
When it may not be suitable
This female die is not a standalone tool and must be used in combination with the corresponding male die and appropriate press or punching equipment. It is intended for specific tooling systems that accept this form factor; it may not fit non-compatible or proprietary tooling without verification of dimensions and mounting interfaces.
Key specifications
 Die shape: round
 Nominal hole diameter: 9.0 mm
 Material/finish: metallic
 Intended application: forming/punching of round holes in busbars and similar materials
 Package weight: approx. 326 g
How to use
Install the female die into the designated holder or die block of the press or punching tool according to the equipment manufacturer's instructions. Position the matching male die opposite the female die and ensure correct alignment before operation. Place the workpiece, for example a busbar, between the dies and perform forming or punching cycles at the recommended press settings for the material and thickness being processed. Regularly inspect the die faces for wear and maintain alignment to preserve hole quality.
What to consider before purchase
 Verify compatibility with your press, tooling system and the matching male die
 Confirm that a 9.0 mm round hole is the required size for your application
 Check material thickness and type to ensure the die is suitable for the load and wear expected
 Plan for spare dies if you expect high cycle counts or abrasive materials
Usage recommendations
Use the Rittal 9.0 mm round female die only with the correct corresponding male die and within the rated capacity of your pressing equipment. Maintain a regular inspection and sharpening or replacement schedule to ensure consistent hole quality and safe operation.
