## Long description

Rittal AS 4055.128 is a metal punch designed for creating round cut-outs in stainless steel panels. It is supplied in a metallic finish and intended for use where precise, clean circular holes are required in thin sheet materials.
Advantages
The tool produces consistent round holes with minimal burrs, helping to maintain panel integrity and appearance. Its compact, handheld design and moderate weight make it easy to position and operate in confined spaces. Built for use with stainless steel, the punch is suitable for robust industrial and electrical enclosure applications.
Suitable for
 Punching Ø holes in stainless steel panels
 Creating feed-throughs for cables, conduits or fittings
 On-site panel modification in control cabinets and enclosures
When it may not be suitable
This punch is intended for use with sheet materials compatible with its tooling and may not be suitable for very thick plate or non-metallic materials. For high-volume production or very large hole diameters, dedicated power tools or press equipment could be more efficient.
Key specifications
 Material suitability: stainless steel (designed for use with metal panels)
 Finish: metallic
 Weight (package): 181 g
 Hole shape: round
How to use
Position the punch over the marked centre of the desired hole on the stainless steel panel and ensure the workpiece is supported underneath. Apply steady, perpendicular force to create the round cut-out. After punching, deburr the hole edges if necessary to remove any sharpness and ensure a clean finish.
What to consider before purchase
 Confirm compatibility with the specific panel material and thickness you will be working on.
 Verify the required hole diameter and whether the punch produces the exact size needed.
 Consider whether manual punching meets your volume and speed requirements or if powered equipment is preferable.
Usage recommendations
For best results, mark the hole centre precisely, support the panel firmly, and perform finishing deburring to maintain a neat appearance and safe edges after punching.
