Deep, Permanent Marks on Metal Surfaces — Deep Enough For Paint and Powdercoat

MarknStamp SPRD-155 deep marking pneumatic portable dot peen machine

When standard dot peen marking isn't deep enough or the surface isn't flat, you need a machine built specifically for the job. The Hand Held Deep Marking Pneumatic machine delivers marks up to 1mm deep on irregular surfaces with variations of up to 12mm — marks that survive painting, shot blasting, anodising and the harshest industrial environments.

Who This Machine Is For

This machine is purpose built for applications where depth and durability are non-negotiable.

Ideal for:

Oil and gas pipelines and heavy fittings requiring lifetime identification
Structural steel and large fabricated components
Defence equipment requiring tamper-evident deep marking
Mining equipment marked before surface treatment
Any application requiring marks that survive coating or treatment processes

What You Can Mark

Serial numbers and part numbers
Asset identification codes
Compliance and traceability marks
Characters up to 5 per second with Vibropeen technology

What Makes It Different

Pneumatic dot peen technology with long stylus strokes handles surface irregularities up to 12mm — ideal for rough cast surfaces, weld seams and uneven industrial components.

Permanent magnets provide superior grip on ferrous surfaces

Special front holding attachments can be customised for specific component shapes and sizes.
