Use this nine-piece engraving punch set from RS PRO to permanently mark numbers on metal components. The punches are easy to use as you can simply place them over a metal sheet and tap the head with a hammer. They produce 8 mm numbers and are compatible with a range of materials, including plastic, clay, wood and leather.


The punches have an easy-to-read font to ensure your markings are fully legible. They're made of a hardened and tempered steel material to prevent breaking, chipping and splintering, making them a safe and durable choice. The set comes in a handy plastic box for easy storage and organisation.


You can use the punches in this set on any material with a 40 Rockwell C hardness. This punch set is a good choice for applications like customising jewellery and signs.
