## Summary description

Rittal AS 4055.770 is an enclosure accessory in a metallic finish. It is supplied as a round die (matrize) with a 6.6 mm diameter suited for panel or enclosure operations. Lightweight and compact, this Rittal accessory is used when forming or preparing circular openings in control cabinets and industrial enclosures.

## Long description

Rittal AS 4055.770 is a metallic-finish round die with a 6.6 mm diameter designed for creating precise circular openings in control cabinets, electrical enclosures and panels. Supplied as a compact female die, it is intended to be used together with the matching male die to punch round holes in sheet metal and busbars. The lightweight construction and standardised shape make it suitable for workshop and on-site panel work where repeatable, clean holes are required.
Advantages
The die provides a consistent 6.6 mm round opening with minimal burr formation when used with the correct male counterpart. Its metallic finish offers corrosion resistance appropriate for industrial environments and ensures dimensional stability over repeated use. The compact and lightweight design simplifies handling and storage, while compatibility with standard male dies enables flexible use across different punching setups.
Suitable for
 Punching round holes (6.6 mm) in control cabinet panels and enclosure sheets
 Forming openings in busbars when combined with the corresponding male die
 Workshop and field operations requiring repeatable circular holes in thin to moderate sheet metal
When it may not be suitable
This female die is not a standalone tool and must be used in combination with the matching male die and an appropriate press or punching tool. It is intended for creating 6.6 mm round holes and therefore is not suitable when different hole diameters or non-circular shapes are required. Very thick material beyond the rated capacity of the punching setup may cause improper forming or damage to the die.
Key specifications
 Shape: round die
 Hole diameter: 6.6 mm
 Finish: metallic
 Type: female die (to be used with corresponding male die)
 Typical applications: panel and busbar punching in control cabinets and enclosures
How to use
Place the female die in the designated holder of the press or punching tool, align the enclosure or busbar material over the die, and position the corresponding male die above. Operate the press according to the tool manufacturer's instructions to form the 6.6 mm round hole. After punching, inspect the hole for burrs and remove any sharp edges if necessary. Follow safe handling practices and wear appropriate personal protective equipment when operating presses or punching tools.
What to consider before purchase
 Ensure availability of the matching male die for the 6.6 mm female die
 Verify that your press or punching tool supports this die size and material thickness
 Confirm the die finish and material suitability for the intended environment
Usage recommendations
Use the Rittal female die in combination with the correct male die and a suitable press rated for the sheet thickness. Regularly inspect dies for wear and keep them clean and lightly lubricated as recommended by tooling guidelines to maintain hole quality and prolong service life.
