## Long description

Rittal AS 4055.537 is a round splitter hole punch designed for creating clean, circular entry points in sheet steel. The tool is built to produce triple splitting for a defined opening size, enabling installation of cable glands or conduit fittings in metal enclosures. The product has a metallic finish and is compact and lightweight for handheld use.
Advantages
The round splitter hole punch provides precise, repeatable holes in sheet steel with a triple-split cutting action that reduces deformation of the surrounding material. Its compact design and low weight make it easy to handle during on-site installation work, and the metallic construction delivers durability for repeated use.
Suitable for
 Creating circular entry holes in sheet steel enclosures
 Preparing openings for cable glands and conduit fittings (around PG 29 / Ø-Loc sizes)
 Electrical cabinet and control panel modifications on site
When it may not be suitable
This tool is intended for use with sheet steel; it may not perform correctly on thicker plate, stainless steel grades with high hardness, or non-metal materials. For precision machining of large numbers of holes or very thin sheet where edge finishing is critical, alternative methods such as punching equipment or drilling with deburring may be more appropriate.
Key specifications
 Shape of hole: round
 Material compatibility: sheet steel
 Cutting action: triple split
 Typical application size: for cable gland / PG 29 / Ø-Loc style openings
 Finish: metallic
 Package weight (approx.): 314 g
How to use
Mark the desired hole position on the sheet steel and secure the workpiece to prevent movement. Place the round splitter punch over the mark and apply steady force to initiate the triple-split cutting action, following the manufacturer's guidance for the required pressure or hand tool to be used. After punching, remove any sharp burrs if necessary and check the fit of the cable gland or fitting before final installation.
What to consider before purchase
 Compatibility with the sheet material thickness and steel grade to be worked
 Required hole diameter and suitability for PG 29 / Ø-Loc type fittings
 Frequency of use and whether a handheld punch is sufficient or a powered/punch press is needed
Usage recommendations
Use the punch on securely clamped sheet steel and remove burrs after cutting. Verify the hole size with the intended gland or fitting and avoid using the tool on materials outside its recommended compatibility to ensure reliable results and tool longevity.
