Ergom N3W 18.8/PG11 Manual Three-Point Punch

The Ergom N3W 18.8/PG11 is a professional manual three-point punch engineered for creating precise, clean holes in sheet metal. This specialized tool is designed to meet the requirements of electrical installations, specifically facilitating the mounting of PG11 standard cable glands. Its robust construction provides the necessary strength for repetitive metalworking tasks, ensuring that every cut is accurate and free of burrs, which is critical for maintaining the integrity of electrical enclosures.

Advantages

The primary benefit of this manual punch is its ability to produce high-quality, burr-free holes without the need for additional finishing work. The three-point cutting design ensures even pressure distribution, which minimizes material deformation and extends the lifespan of the tool. Its compact and manual nature makes it highly portable and ideal for use in tight spaces or on-site installations where power tools may not be practical or necessary. The durable materials used in its construction guarantee long-term reliability for professional panel builders and electricians.

Suitable for

• Cutting holes for PG11 cable glands
• Electrical cabinet and enclosure modifications
• Sheet metal processing in electrical installations
• On-site maintenance and repair tasks

When it may not be suitable

This tool is not intended for use on hardened steel, stainless steel of significant thickness, or non-metallic materials. It is specifically calibrated for standard sheet metal thicknesses used in electrical enclosures and may not perform effectively on materials exceeding its design capacity.

Key specifications

• Hole diameter: 18.8 mm
• Compatibility: PG11 standard
• Operation: Manual three-point punch
• Material application: Sheet metal

How to use

To use the Ergom N3W 18.8/PG11, first mark the center point where the hole is required on the sheet metal. Drill a pilot hole of the appropriate size to accommodate the punch bolt. Insert the punch bolt through the pilot hole, attach the cutting die on the opposite side, and tighten the nut manually or with a wrench. As the bolt is tightened, the three-point cutting edges will cleanly shear through the metal to create the desired hole.

What to consider before purchase

• Verify the required hole diameter for your specific cable gland
• Ensure the sheet metal thickness is within the tool's operational limits
• Confirm that you have sufficient clearance around the hole location for the tool's operation

Usage recommendations

Always ensure the punch is properly aligned before applying force to prevent uneven cutting. Regularly clean and lubricate the threads of the punch bolt to maintain smooth operation and extend the tool's service life.
