Numeric Punch/Stamp Set Beta Tools 3 mm digits (model 100030K0) 10-piece metal stamps

Metal numeric stamp set Beta Tools 3 mm digits (model 100030K0) is a 10-piece kit of hardened metal punches designed to create permanent numeric impressions on metal, wood or plastic. Each stamp features a single digit sized approximately 3 mm in height, enabling clear, compact marking for serial numbers, component identification and workshop labelling. The stamps are intended for hand striking with a hammer and for use in standard marking operations in workshops and production settings.

Advantages

The set provides durable, wear-resistant metal punches that maintain character clarity over repeated use. Individual digit stamps allow flexible numbering combinations without the need for custom dies, and the compact 3 mm character height is suitable for marking small parts or tight layouts. The design supports straightforward manual use: align the chosen digit, strike with a hammer and produce a permanent embossed or indented mark.

Suitable for

• Serial numbering of metal components
• Identification of tools, parts and assemblies
• Workshop marking on steel, aluminum, brass, wood and hard plastics
• Proofing or indexing small items where space for marks is limited

Key specifications

• Set composition: 10 individual digit stamps (0–9)
• Character height: 3 mm
• Material: hardened metal punch (tool steel)
• Intended marking method: hand striking with hammer
• Mark type: embossed or indented permanent numerals

How to use

Select the required digit stamp and position its tip perpendicular to the workpiece surface at the desired marking location. Hold the stamp firmly and strike the head with a suitable hammer using controlled force; multiple blows may be required depending on material hardness. For aligned multi-digit marks, use a straightedge, jig, or temporary guide to maintain consistent spacing and orientation. Clean the stamps after use to remove debris and protect the faces from corrosion.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Test strike on a scrap piece to verify impression depth and alignment before marking finished parts. Avoid excessive striking force to reduce head mushrooming; periodically dress the striking face if necessary and store the set in a dry place to preserve tool life.
