The King Tony 5mm Letter Punch Set A–Z Heavy Duty is a professional-grade marking tool set designed for permanent letter marking on metal and other hard materials. Manufactured from high-quality chrome vanadium alloy steel, this set delivers sharp, consistent impressions and long service life in workshop, engineering, and industrial environments. Each punch is precision hardened and tempered to ensure controlled impact performance and reliable marking accuracy. The working end is hardened to approximately HRC60 for clean impressions, while the striking end is softened to approximately HRC40 to absorb impact force, reducing chipping and extending tool lifespan. The set includes the full alphabet from A to Z, with an additional ampersand (&) character for extended marking versatility.
