• Material compatibility: Steel
• Type: Round hole punch
• Application: Professional metalworking

How to use

To use the Erko WO 18.5mm punch, first mark the exact center point where the hole is required on the steel sheet. Ensure the punch is properly aligned with the pilot hole if applicable. Apply consistent pressure using a compatible hydraulic or manual punching device to drive the punch through the material. Once the punch has passed through, remove the tool and clear away the metal slug to ensure a clean finish.

What to consider before purchase

• Verify the thickness of the steel sheet against the tool's maximum capacity
• Ensure compatibility with your existing punching equipment or press
• Confirm the required hole diameter matches your specific project needs

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating metal punching tools. Regularly inspect the punch for signs of wear to maintain optimal cutting performance and ensure the longevity of the tool.
