## Long description

Rittal AS 4055.776 metallic — 14.0 mm round die (Matrize) is a precision accessory designed for forming or punching 14.0 mm circular holes in metal enclosures and related components. Supplied as a female round die, it is intended for use in combination with the corresponding male die to produce clean, accurately sized round holes. The tool is suitable for modifications to electrical cabinets, busbar processing and general panel fabrication where reliable, repeatable circular knockouts are required.
Advantages
The Rittal 14.0 mm round die is manufactured for consistent hole quality and dimensional accuracy, reducing rework and fitting time. Its metallic construction offers durability for repeated use in workshop presses and production environments. Designed for compatibility with Rittal enclosure systems and matched male dies, the accessory enables reliable punching of round holes in busbars and sheet metal with minimal deformation.
Suitable for
 Creating 14.0 mm circular openings in electrical enclosures and panels
 Punching holes in busbars when used together with the corresponding male die
 Cable entry preparation and fitting of gland or conduit components
 Workshop press operations and small-scale fabrication tasks
When it may not be suitable
This female die must be used paired with the appropriate male die; it will not function alone for punching operations. It is intended for metal sheet and busbar work — it may not be suitable for non-metal materials, extremely thick plate, or applications requiring profiles or non-circular openings.
Key specifications
 Die shape: round
 Nominal hole diameter: 14.0 mm
 Material: metallic construction for durability
 Intended use: forming/punching 14.0 mm circular holes in sheet metal and busbars

How to use
Install the female die in the press or die-holder according to the press manufacturer's instructions, then locate and fit the corresponding male die. Position the sheet metal or busbar between the male and female die, ensure correct alignment and clamping, and operate the press to form or punch the 14.0 mm round opening. After punching, remove the slug and inspect the hole for correct dimensions and edge quality. Follow standard workshop safety procedures and use appropriate personal protective equipment.
What to consider before purchase
 Ensure you have the corresponding male die that matches this female 14.0 mm round die
 Confirm compatibility with your press or die-holder and the maximum material thickness you plan to work with
 Verify that a 14.0 mm circular hole meets your component or cable gland requirements
 Consider the material type (sheet metal or busbar) and whether the die's metallic construction suits your application
Usage recommendations
Use the Rittal female die together with the matching male die and a press rated for the material thickness. Maintain dies by cleaning contact surfaces after use and inspect regularly for wear to sustain hole quality and ensure safe operation.
