Number Punch Set:5mm x 60 - 9pcs Set

A precision number punch set designed to mark digits and symbols onto metal, plastic, or other hard surfaces without drilling or heat. The set contains nine individual punches, each with a nominal diameter of 5mm and a nominal length of 60mm, ensuring consistent depth and clarity for industrial identification tasks. Unlike permanent laser or engraving methods, punch marks are non-conductive and do not affect the electrical continuity of coated components, making them ideal for quality control and traceability. Buyers select these sets for their simplicity and cost-effectiveness, requiring only a hammer or tapping tool to apply marks. To choose the appropriate configuration, verify the required character size matches the 5mm diameter and ensure the 60mm length provides sufficient striking clearance for your specific workpiece thickness and setup.

• Marking serial numbers and lot codes on steel, aluminum, and copper components in fabrication workshops.
• Applying temporary or permanent identification tags to electrical panels and wire terminals in industrial maintenance facilities.
• Dating parts and marking batch numbers on automotive or aerospace assemblies during quality assurance inspections.
