Ergom N3WY/28,6/PG21 Hydraulic Three-Point Punch

The Ergom N3WY/28,6/PG21 is a professional-grade hydraulic three-point punch engineered for high-precision hole cutting in sheet metal. This specialized tool is designed to deliver clean, burr-free edges, which is essential for maintaining the integrity of electrical enclosures and control panels. Its robust construction ensures long-term durability and consistent performance in demanding industrial environments, facilitating efficient and accurate punching of PG21 standard holes.

Advantages

The primary benefit of this hydraulic punch is its ability to produce perfectly shaped holes without the need for extensive filing or finishing. The three-point design ensures optimal centering and stability during the punching process, which significantly reduces mechanical stress on the tool and the workpiece. Its hydraulic operation minimizes the physical effort required by the operator, allowing for repetitive, high-quality results even in thick sheet metal applications.

Suitable for

• Electrical installation projects
• Control panel and switchgear manufacturing
• Sheet metal fabrication workshops
• Industrial maintenance and repair tasks

This tool may not be suitable for cutting through hardened steel, stainless steel of excessive thickness, or non-metallic materials like wood or plastic. It is specifically calibrated for standard sheet metal applications and may experience premature wear or failure if used on materials exceeding its rated capacity or hardness specifications.

Key specifications

• Punch type: Hydraulic three-point punch
• Hole size: PG21 standard
• Material compatibility: Sheet metal
• Operation method: Hydraulic

To use the Ergom N3WY/28,6/PG21, first mark the center point where the hole is required and drill a pilot hole of the appropriate diameter 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 metal, and connect the hydraulic mechanism. Gradually apply hydraulic pressure until the punch cleanly shears through the material, then release the pressure to remove the tool and the punched slug.

What to consider before purchase

• Verify that the PG21 hole size matches your specific cable gland or component requirements.
• Ensure you have access to a compatible hydraulic pump or manual hydraulic driver.
• Check the maximum material thickness capacity of your specific sheet metal type.

For optimal tool longevity, ensure the punch and die surfaces are kept clean and lightly lubricated before each use. Regularly inspect the cutting edges for signs of dulling and avoid exceeding the recommended material thickness to prevent structural damage to the punch.
