Number Punches

About Number Punches

Number punches are essential marking tools used to permanently stamp numerical digits onto metal, leather, wood and other materials. Each set contains individual punches for digits 0-9, allowing tradespeople and engineers to mark part numbers, dates, measurements and identification codes with precision. MyToolShed.co.uk stocks professional number punch sets from trusted brands including Draper, Faithfull and Priory, designed to deliver clear, consistent impressions across a range of materials and applications.

Available in various sizes typically ranging from 2mm to 10mm character heights, these hardened steel tools withstand repeated hammer strikes whilst maintaining sharp, defined edges. Quality number punch sets are heat-treated for durability and come organised in storage cases for easy identification and protection. Whether marking fabricated components, tool inventories or engineering projects, number punches provide a permanent identification solution that won't fade or wear over time.

Applications

• Engineering and fabrication: Marking part numbers, batch codes and assembly sequences on metal components
• Automotive mechanics: Identifying custom parts, engine numbers and modification dates
• Metal fabricators and welders: Stamping job numbers, material grades and inspection dates
• Maintenance engineers: Asset tagging, equipment numbering and service date recording
• Leatherwork and crafts: Adding decorative numbers or identification to leather goods
• Tool and equipment marking: Permanent identification for inventory control and theft prevention
• General workshops: Dating projects, marking measurements and creating reference numbers

Choosing The Right Number Punches

Character size determines readability and application suitability. Smaller 2-4mm punches suit detailed work and limited space, whilst 6-10mm sizes provide better visibility for asset marking and identification tags. Consider the viewing distance and material thickness when selecting size.

Material quality affects longevity and impression clarity. MyToolShed.co.uk offers hardened and tempered carbon steel punches that resist mushrooming and maintain sharp edges through extensive use. Premium sets feature properly heat-treated striking ends to prevent chipping.

Storage case quality keeps individual punches organised and protected. Look for clearly labelled compartments that allow quick digit selection and prevent loss. Robust cases protect the punches during transport and storage.

Brand reputation matters for consistent quality. Established manufacturers like Draper, Faithfull and Priory maintain strict tolerances ensuring uniform character height and depth across all digits in the set.

Safety Information

Always wear safety glasses when using number punches to protect against metal fragments and debris. Ensure the workpiece is securely clamped or supported to prevent movement during striking. Use an appropriate hammer weight for the punch size—excessive force can damage the punch or workpiece. Inspect punches regularly for mushroomed striking ends and file smooth to prevent dangerous fragmentation. Work on a stable surface and keep fingers clear of the striking zone.

Frequently Asked Questions

What size number punch set do I need?
For general workshop use, 4-6mm sets offer versatility for most marking tasks. Smaller 2-3mm sets suit precision engineering, whilst 8-10mm sizes work best for asset tagging and outdoor applications where visibility matters.

Can number punches be used on hardened steel?
Standard number punches work best on mild steel, aluminium, brass and softer materials. Attempting to mark hardened steel may damage the punch. Anneal or use specialist carbide-tipped punches for hardened materials.

How do I prevent unclear impressions?
Ensure the punch is held perpendicular to the surface and strike with a single, firm blow. Centre punch a small location mark first for accurate positioning. Clean the punch face regularly and work on a solid backing surface for best results.
