Ergom NWY 25.5/M25 Round Punch

The Ergom NWY 25.5/M25 round punch is a specialized industrial tool engineered for creating precise, clean circular openings in sheet metal. Designed specifically for electrical installation tasks, this punch facilitates the seamless mounting of M25 cable glands into enclosures, control panels, and junction boxes. Its robust construction ensures high durability and consistent performance, making it an essential component for professionals working in electrical engineering and metal fabrication.

Advantages

This round punch offers exceptional precision, ensuring that every hole cut is perfectly circular and free of burrs, which significantly reduces the need for secondary finishing work. The high-quality materials used in its manufacturing provide long-lasting wear resistance, even when used frequently in demanding workshop environments. Its design optimizes the force application, allowing for efficient and smooth operation during the punching process, which helps in maintaining high productivity levels during large-scale electrical installations.

Suitable for

• Creating precise openings for M25 cable glands
• Installation of electrical components in metal enclosures
• Preparation of control panels and distribution boards
• Industrial metalworking and electrical maintenance tasks

When it may not be suitable

This tool is specifically calibrated for thin sheet metal and is not intended for use on hardened steel, thick metal plates, or non-metallic materials such as wood or plastic. Attempting to use this punch on materials exceeding its design specifications may result in damage to the tool or poor cut quality.

Key specifications

• Punch diameter: 25.5 mm
• Compatibility: M25 cable glands
• Material application: Sheet metal
• Design: Round punch

How to use

To use the Ergom NWY 25.5/M25, first mark the exact center point where the hole is required on the sheet metal surface. Drill a pilot hole that matches the diameter of the punch's draw bolt. Insert the punch assembly through the pilot hole, ensuring the cutting edges are properly aligned with the surface. Use a compatible manual or hydraulic driver to tighten the bolt, which will draw the punch through the metal to create a clean, accurate opening. Once the cut is complete, disassemble the tool and remove the metal slug.

What to consider before purchase

• Verify the required hole diameter for your specific cable gland
• Ensure your current punching driver is compatible with this tool
• Check the thickness of the sheet metal to ensure it falls within the tool's operational range

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating metal punching tools. Regularly inspect the cutting edges for signs of wear and keep the threads of the draw bolt lubricated to ensure smooth operation and extend the lifespan of the tool.
