Hydraulic Punch Rittal 4055070 hand hydraulic punch set for straight punches M16 M20 M25 M32 M40 M50

The Rittal Hydraulic Punch hand punch set 4055070 contains a range of straight hydraulic punches designed to produce clean, circular holes in metal enclosures and panels. Intended for use where portability and controlled, repeatable force are required, this manual hydraulic system covers common metric sizes for electrical and industrial sheet-metal work. The set is suitable for on-site modifications, cabinet fabrication and maintenance tasks where power tools are impractical or access is limited.

Advantages

This hand hydraulic punch set provides precise, burr-reduced hole cutting with consistent force application for each punch size. The manual hydraulic operation offers controlled punching without the vibration or heat associated with power tools, helping preserve surrounding material and finishes. The included punch sizes allow users to address multiple common cable gland and conduit entry diameters with a single portable tool set.

Suitable for

• Punching circular holes in electrical cabinets and junction boxes
• On-site panel modifications and retrofits
• Maintenance and repair work where portable tools are required
• Sheet-metal workshops and small-scale fabrication

When it may not be suitable

This manual hydraulic punch set is not intended for high-volume industrial production where automated or power-operated punching presses are more efficient. It may be less suitable for very thick plate steel beyond the rated capacity of hand hydraulic punches or for materials that require specialty tooling, such as hardened steel or unconventional alloys.

Key specifications

• Punch type: straight hydraulic punches for circular holes
• Punch sizes included: metric sizes covering M16, M20, M25, M32, M40, M50 hole diameters
• Operation: manual hydraulic actuation for controlled force application
• Typical applications: electrical enclosures, panels, sheet-metal up to the rated thickness for hand hydraulic punches
• Portability: handheld, designed for field and on-site use

How to use

Select the appropriate punch size for the required hole diameter, clamp the workpiece securely and position the punch assembly over the marked centre point. Operate the hydraulic pump to apply force until the punch cleanly cuts through the material. After punching, retract the punch and remove the slug; deburr the hole if necessary to achieve the required finish. Follow standard safety practices such as securing the sheet, wearing eye protection and verifying the material thickness is within the tool’s rated capacity.

What to consider before purchase

• Verify the tool’s rated material thickness and compatibility with the metals you intend to punch
• Confirm the included punch diameters match the cable glands, conduits or fittings you will use
• Consider portability needs versus production volume — manual hydraulics suit fieldwork and low-to-medium volume tasks
• Ensure spare parts and maintenance support are available for hydraulic components

Usage recommendations

For best results, mark and centre-punch the hole location before fitting the hydraulic punch. Use appropriate clamps or a mounting adapter to stabilise thin or flexible panels. Inspect punches and dies for wear and replace worn tooling to maintain hole quality and safe operation.
