Enclosure accessory Rittal AS 4055.547 – metallic Spalt-Blechlocher for steel sheet, PG 36 Ø-Loc

Rittal AS 4055.547 is a metal sheet punch designed for creating round cut-outs in steel sheet. The tool is supplied in a metallic colour and comes as a compact, single-piece unit with a package weight of approximately 509 g. It is intended for precise, repeatable hole punching in sheet metal where circular openings are required.

Advantages

The punch provides clean, circular cut-outs in steel sheet with consistent diameter and minimal deformation at the edges. Its robust metallic construction ensures durability during repeated use and maintains alignment for accurate results. The compact weight and straightforward design make it easy to handle and integrate into manual or bench-mounted operations.

Suitable for

• Punching round openings in steel sheet
• Making PG 36 compatible cable or conduit entries
• Shop or workshop metalworking tasks requiring repeatable round holes

When it may not be suitable

This punch is designed specifically for steel sheet and for producing round cut-outs of the matching diameter; it may not perform as intended on very thick plate, hardened steels, non-metal materials, or when a different hole size is required. For precision work on thin or delicate materials where deformation must be avoided, alternative tooling or support may be necessary.

Key specifications

• Material: metal construction suitable for steel sheet
• Application: round hole punch for steel sheet
• Colour: metallic
• Approximate package weight: 509 g
• Hole type: circular (PG 36 / Ø-compatible as indicated by offer name)

How to use

Position the punch over the marked location on the steel sheet and secure the sheet to prevent movement. Apply force using the appropriate press or manual drive compatible with the punch until the circular blank is fully cut out. Remove the punched-out slug and inspect the hole for burrs; deburr if required. Follow standard safety procedures for sheet metal work, including eye and hand protection.

What to consider before purchase

• Confirm compatibility with the desired hole diameter (PG 36 / Ø specification)
• Ensure the punch is suitable for the steel thickness and grade you will work with
• Verify your press or mounting setup can accommodate this punch
• Consider whether additional deburring or finishing will be needed after punching

Usage recommendations

Use with a stable press or fixture and clamp the workpiece securely. Check the punch edge regularly and replace if worn to maintain clean cut-outs. For consistent results, match the punch to the material thickness and perform test punches on scrap material before production.
