Number Punch Set (digits) 8 mm, Beta Tools 100080K0 — metal number stamps for marking

Beta Tools Number Punch Set (digits) 8 mm provides a set of metal digit stamps designed for manual marking of numbers onto metal, wood and other softer materials. The set is intended for imprinting serial numbers, dates and component identifiers directly into parts or assemblies using a hammer strike. The durable construction and clear digit profiles support repeatable, legible impressions for traceability and inventory control in workshops, production and maintenance environments.

Advantages

The punch set features hardened steel construction for wear resistance and consistent impression quality. Each digit has a clearly defined 8 mm high profile to ensure uniform size and readability across a range of substrates. The compact set is compatible with standard hammer striking and does not require specialised equipment, enabling fast and economical marking on site. The design minimises deformation of the stamped surface while producing deep enough impressions for long-term identification.

Suitable for

• Marking serial numbers on metal parts
• Stamping production dates on housings and plates
• Applying numeric identifiers on wooden components or soft alloys
• Workshop, maintenance and small-scale manufacturing marking tasks

Key specifications

• Digit height: 8 mm
• Material: hardened steel
• Type: numeric digit stamps (0–9)
• Operation: manual hammer striking
• Finish: machined stamp face for clear impressions

How to use

Select the required digit stamp and position its face squarely on the target surface. Hold the stamp firmly and use a standard hammer to strike the top of the punch with controlled force until a clear impression is formed. For multi-digit markings, align stamps sequentially or use a guide to ensure even spacing. When stamping on thin or coated materials, support the workpiece on a solid backing to reduce bending and achieve a sharper mark. Clean the stamp faces after use to remove debris and preserve imprint quality.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves when striking. Test on a scrap piece of the same material to determine the required striking force and verify spacing. Avoid excessive force that could damage thin components; for hard or hardened surfaces consider pre-marking using a center punch or selecting a suitable alternative marking method.
