Ergom NW 25.5/M25 Punch Tool

The Ergom NW 25.5/M25 punch tool is a professional-grade instrument engineered for creating precise, clean holes in metal sheets. Designed specifically for the installation of M25 cable glands, this tool is an essential component for electrical panel builders and industrial technicians who require high accuracy and efficiency in their daily operations. Its robust construction ensures long-term reliability even under demanding workshop conditions.

Advantages

This punch tool offers exceptional precision, allowing for perfectly sized openings that ensure a secure fit for cable glands, which is critical for maintaining the integrity of electrical enclosures. The design minimizes material deformation around the hole, resulting in a clean finish that requires no additional deburring or manual refinement. Its ergonomic build simplifies the punching process, reducing physical strain on the operator while significantly increasing productivity during large-scale installation projects.

Suitable for

• Electrical panel building and cabinet assembly
• Installation of M25 cable glands in metal enclosures
• Industrial maintenance and electrical infrastructure projects
• Workshop metalworking tasks requiring precise hole diameters

When it may not be suitable

This tool is specifically calibrated for metal sheets and may not be suitable for use on hardened steel, extremely thick plates, or non-metallic materials like thick plastics or wood. It is not intended for use with materials exceeding the manufacturer's recommended thickness capacity.

Key specifications

• Hole diameter: 25.5 mm
• Compatible thread size: M25
• Material compatibility: Metal sheets
• Application: Cable gland mounting

How to use

To use the Ergom NW 25.5/M25 punch tool, first mark the exact center point where the hole is required on the metal sheet. Drill a pilot hole of the appropriate size to accommodate the punch bolt. Insert the punch bolt through the pilot hole, attach the punch and die components on either side of the sheet, and tighten the mechanism. As the bolt is tightened, the punch will cleanly shear through the metal, creating a precise 25.5 mm opening suitable for M25 cable glands.

What to consider before purchase

• Verify the thickness of the metal sheet to ensure it falls within the tool's operating range
• Ensure the pilot hole drill bit size matches the requirements of the punch bolt
• Confirm that the M25 size is correct for your specific cable gland hardware

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating metal punching tools. Regularly lubricate the punch bolt threads to maintain smooth operation and extend the service life of the tool.
