Ergom N3W 16.2/M16 Manual Three-Point Punch

The Ergom N3W 16.2/M16 is a professional-grade manual three-point punch engineered for high-precision hole cutting in sheet metal. This specialized tool is designed to create clean, burr-free holes with a diameter of 16.2 mm, which are perfectly sized for M16 cable glands. Its robust mechanical design allows for reliable operation in both demanding workshop conditions and on-site field installations, providing a consistent and efficient solution for electrical panel preparation.

Advantages

The primary benefit of this manual punch is its three-point cutting geometry, which ensures that the force is distributed evenly during the punching process, resulting in a perfectly circular hole without deforming the surrounding metal. The tool is built for durability, featuring high-quality materials that withstand frequent use in industrial environments. Its compact and portable design eliminates the need for external power sources, making it an essential tool for technicians who require mobility and precision in their daily tasks.

Suitable for

• Creating precise 16.2 mm holes in sheet metal panels
• Installing M16 cable glands in electrical enclosures
• Professional electrical installation and maintenance work
• Field operations where power tools are impractical

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 plates, or non-metallic materials. It may not be suitable for high-volume production lines where automated hydraulic punching systems are required for speed and efficiency.

Key specifications

• Hole diameter: 16.2 mm
• Compatibility: M16 cable glands
• Operation type: Manual three-point punch
• Material application: Sheet metal

How to use

To use the Ergom N3W, first mark the center point where the hole is required and drill a pilot hole of the appropriate size to accommodate the punch bolt. Insert the punch bolt through the pilot hole and attach the cutting die on the opposite side of the sheet metal. Tighten the nut manually or with a wrench to draw the punch through the material. Continue tightening until the punch has completely penetrated the metal, then unscrew the assembly to remove the slug and finish the process.

What to consider before purchase

• Ensure the thickness of your sheet metal is within the tool's operational capacity
• Verify that the 16.2 mm diameter matches your specific cable gland requirements
• Consider the accessibility of the workspace, as manual operation requires space to turn the wrench

Usage recommendations

Always ensure the punch and die are properly aligned before applying force to prevent damage to the tool or the workpiece. Regularly clean and lubricate the punch bolt threads to maintain smooth operation and extend the service life of the device.
