36-piece letter and number punch set, hardened carbon steel, 4 mm high, for stamping on metal, leather and wood

This set of 36 professional punches is designed for discerning craftspeople who want to permanently mark letters and numbers on a variety of materials. Made from high-carbon steel, each punch is forged, hardened, and tempered to ensure superior hardness (approximately 58–62 HRC) and increased durability. The consistent 4 mm height ensures a uniform marking depth, suitable for a range of materials such as full-grain leather, ash or walnut wood, as well as non-ferrous metals (copper, brass, 925 silver, 18-karat gold). The included case makes storage and transport easy, while the polished finish minimizes micro-scratches on delicate surfaces. Usable with a rubber- or wooden-headed hammer, this tool is ideal for personalizing jewelry, crafting signage, or decorative engraving on metal or leather objects.
