The Ergom N3W 50.5 is a professional manual three-point punch engineered for creating precise 50.5 mm diameter holes in metal sheets. This tool is specifically designed to accommodate M50 cable glands, making it an indispensable asset for electrical installations and the assembly of control cabinets. Its robust design ensures reliable performance and clean results, allowing for efficient hole punching in various industrial environments.
Advantages
The primary advantage of the Ergom N3W 50.5 lies in its specialized three-point cutting geometry, which ensures that each hole is perfectly circular and free of burrs. This precision reduces the need for secondary finishing work, saving time during installation. The tool is built for durability, utilizing high-quality materials that withstand the rigors of frequent use in demanding industrial settings. Its manual operation provides excellent control and portability, as it does not require an external power source or hydraulic pump to function effectively.
Suitable for
- Creating precise 50.5 mm holes for M50 cable glands
- Electrical installation work in metal enclosures
- Control cabinet assembly and modification
- Industrial metal sheet processing
When it may not be suitable
This tool is not intended for use on materials other than standard metal sheets, such as hardened steel, thick plate metal, or non-metallic materials like wood or plastic. It is also not suitable for high-volume production lines where automated or hydraulic punching systems are required for rapid, repetitive tasks.
Key specifications
- Hole diameter: 50.5 mm
- Compatibility: M50 cable glands
- Operation type: Manual
- Cutting mechanism: Three-point punch
How to use
To use the Ergom N3W 50.5, first mark the 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 cutting die on the opposite side, and tighten the nut manually or with a wrench. As the bolt is tightened, the three-point punch will cleanly cut through the metal sheet to create the 50.5 mm hole. Once the punch has passed through the material, unscrew the bolt to remove the tool and clear the metal slug.
What to consider before purchase
- Ensure the thickness of the metal sheet is within the recommended range for manual punching tools
- Verify that the required hole size matches the 50.5 mm specification for your specific cable gland
- Confirm that you have sufficient clearance around the installation area to operate the manual tightening mechanism
Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating the punch. Keep the cutting surfaces clean and lightly lubricated to maintain optimal performance and extend the lifespan of the tool.
