Enclosure accessory Rittal AS 4055.748, red — stamping tool 18.0 mm round

Rittal AS 4055.748 is a red enclosure accessory supplied as an 18.0 mm round stamping tool intended for use with industrial enclosures, electrical cabinets and panel housings. The tool is designed to create clear circular impressions or marks on metal and sheet surfaces for identification, labelling and preparatory work during maintenance, assembly and electrical installation tasks. When used together with appropriate dies, the stamping system supports punching round holes in busbars from 6.6 mm to 21.5 mm diameter.

Advantages

The stamping tool features a round 18.0 mm stamping face for consistent, repeatable impressions and is finished in red for quick visual identification among other accessories. It is compatible with the Rittal stamping/die system so it can be combined with dies to punch round holes in busbars within the stated diameter range. The design is intended to integrate with enclosure and cabinet workflows, allowing marking and hole preparation without the need for separate marking devices or complex setups.

Suitable for

• Creating circular impressions on metal panels and enclosure doors for identification and labelling
• Preparing guide marks for drilling or punching during electrical installation and assembly
• Use with dies to punch round holes in busbars (6.6 mm–21.5 mm) when combined with compatible stamping components
• Maintenance and service work where quick and repeatable marking is required

When it may not be suitable

This stamping tool is intended for marking and punching tasks on sheet metal and busbars; it is not a general-purpose hand tool for cutting, shaping or heavy machining of enclosure materials. Very thick or hardened materials that exceed the stated punching range or that require specialised cutting equipment may not be suitable for use with this tool.

Key specifications

• Stamping face: round, 18.0 mm diameter
• Colour: red finish for visual identification
• Application: marking and creating circular impressions on enclosures and panels
• Compatible punching range with dies: round holes from 6.6 mm to 21.5 mm in busbars
• Intended environment: industrial enclosures, electrical cabinets, panel housings

How to use

Select the appropriate die if punching holes in busbars and assemble the stamping tool into the compatible holder or press according to the stamping system instructions. Position the tool on the intended location of the panel or busbar, ensure stable support and alignment, then actuate the stamping or pressing mechanism to make the impression or punch the hole. For marking only, use controlled force to produce a clear, repeatable circular impression without distorting surrounding material. Follow the manufacturer’s guidance for die selection, assembly and safe operation.

What to consider before purchase

• Confirm compatibility with your existing stamping holder, press or Rittal stamping/die system
• Check that the 18.0 mm round stamping face meets your marking or hole-size requirements
• Verify the material thickness and hardness of panels or busbars to ensure they fall within the tool and die punching capacity (6.6–21.5 mm hole range when using dies)
• Assess whether the red finish is required for visual identification in your workflow

Usage recommendations

Use the stamping tool together with the correct dies and a stable press or holder to achieve precise, repeatable impressions and punched holes. Wear appropriate personal protective equipment when punching metal and follow safe handling practices for stamping tools and dies.
