Sealey 36 Piece Letter and Number Punch Set 4mm

About this tool

The 4mm character height variant offers an excellent middle ground between fine detail work and general-purpose marking applications. At 60mm long, these compact punches deliver precise control whilst producing clear, legible characters suitable for a wide range of workshop tasks, from component identification to quality control marking. Crafted from high carbon steel and hardened and tempered to professional standards, these punches maintain their integrity through extensive use. The chemical blackening process provides reliable corrosion protection whilst giving the punches a distinctive, professional finish. This comprehensive 36-piece set includes every letter of the alphabet, all numerical digits, and the practical ampersand symbol, with the number 6 conveniently functioning as number 9 when inverted. The 4mm character size produces markings that are substantial enough for easy reading yet refined enough for professional applications across automotive, engineering, and general metalworking sectors. The supplied composite case protects your punches and maintains organisation throughout their working life.
