## Long description

Rittal AS 4055.528 is a round splitter hole punch designed for creating clean, circular holes in sheet steel. Finished in a metallic colour, the tool is intended for use with steel panels where a precise round opening is required. The compact tool is lightweight and aimed at panel fabricators and installers working with steel enclosures and sheet metal components.
Advantages
The punch produces a neat, round hole in sheet steel with a splitter action that helps separate material cleanly and reduce burr formation. Its metallic finish provides corrosion resistance suitable for workshop environments. The tool’s compact size and moderate weight make it easy to handle for repetitive punching tasks.
Suitable for
 Punching round holes in steel sheet panels
 Creating cable or conduit entry points in enclosures
 Panel fabrication and on-site installation work
When it may not be suitable
This punch is intended specifically for sheet steel and may not perform as intended on non-ferrous metals, very thin laminates, or hardened steels. It is also not a replacement for powered hole saws when very large-diameter holes, very high production rates, or variable hole sizes are required.
Key specifications
 Shape of hole: round
 Material compatibility: sheet steel
 Finish: metallic colour
 Weight (package): 167 g
How to use
Mark the desired hole position on the steel panel, align the round splitter punch with the mark, and apply steady mechanical force as specified by the tool manufacturer until the punch creates the hole. After punching, remove any loose material and deburr the edge if necessary to ensure a clean finish suitable for cable or conduit passage.
What to consider before purchase
 Confirm the punch diameter matches the required hole size for cables or fittings.
 Ensure compatibility with sheet steel thicknesses you will work with.
 Consider whether a manual punch suits your production volume or if a powered solution is needed.
Usage recommendations
Use the punch on properly supported steel panels to avoid deformation, wear appropriate personal protective equipment, and deburr punched edges before inserting cables or fittings.
