With the Turnus 329-210 letter punch set, you create clear, permanent, and indelible markings on metal components, machinery, and tools. This 27-piece set includes letters a through z plus the ampersand (&), allowing you to stamp serial numbers and identification codes with a distinct 10 mm character height. Manufactured from hardened tool steel with punch heads treated to 58–61 HRC, they withstand repeated impacts on materials with a tensile strength up to 900 N/mm² (27 HRC). The robust 12 mm body width and 80 mm total length provide stable handling and maximum control with every hammer blow.
