## Long description

Rittal AS 4055.525 is a round splitter hole punch designed for use with sheet steel. The tool creates a clean circular cut with a triple-splitting action, suitable for producing M25-sized openings in steel panels and enclosures. It is finished in a metallic colour and supplied as a compact, lightweight accessory for panel fabrication and electrical enclosure work.
Advantages
The round splitter hole punch provides precise round openings in sheet steel with a triple-splitting mechanism that reduces deformation and improves edge quality. Its compact design and low weight make it easy to handle and position on panels, while the metallic finish offers basic corrosion resistance and a professional appearance.
Suitable for
Cutting M25 circular holes in steel sheet panels
Preparing openings for cable glands, conduit entries, or small fittings
Electrical enclosure and control cabinet modifications
On-site panel work where lightweight, manual tools are required
When it may not be suitable
This hole punch is intended for sheet steel and for creating M25-sized round holes; it may not perform correctly on thicker plate materials, stainless steel grades with high hardness, or non-metal materials such as plastics without appropriate tooling. For larger hole diameters or precision-machined finishes, a different cutting method or power tool may be preferable.
Key specifications
Hole shape: round
Typical hole size: M25 / Ø suitable for M25 fittings
Material application: sheet steel
Cutting method: triple splitting action
Finish: metallic colour
Weight (package): 133 g
How to use
Mark the desired hole centre on the steel panel, secure the sheet to prevent movement, and position the round splitter punch over the mark. Apply steady manual force or use an appropriate press to operate the punch so the triple-splitting cutters penetrate the sheet and create the circular opening. Deburr the cut edge if necessary and install the intended gland or fitting.
What to consider before purchase
Verify the tool is rated for the thickness and steel grade you will be working with
Confirm the hole diameter matches the fittings or glands you plan to install (suitable for M25)
Check compatibility with your punching press or manual operation method
Usage recommendations
Use the punch on properly supported sheet steel and follow manufacturer safety guidance; after cutting, remove sharp burrs and verify hole dimensions before fitting components.
