⚡ At a Glance
- • Marking Accuracy: Finds the centre of round bars up to 35 mm diameter with precise alignment
- • Best for: Metalworkers, model makers and small workshops needing reliable centre marks
- • Not ideal for: Round bars larger than 35 mm diameter or specialised industrial setups
Hardened EN31 alloy steel construction keeps the tip geometry stable for accurate marking. Designed to centre punch round stock up to 35 mm quickly and reliably.
Precise centre marks, with EN31 hardened and ground punch tip
EN31 alloy steel is hardened and ground to maintain a consistent tip geometry through repeated use. The ground finish reduces edge chipping and helps the tip register cleanly on curved surfaces.
Accurate, repeatable centre marks make drilling straight and reduce the need for rework on small components.
Quick alignment and marking, with simple hand-operated action
Hand tool design allows rapid positioning and impact marking without complex setup or jigs. The tool registers on round stock and creates a clear centre reference in a single motion.
Speed up repetitive marking tasks and get consistent starting points for pilot drilling, saving time during preparation.
Durable workshop construction, with long-life EN31 alloy steel
EN31 alloy steel is specified as hard and ground for long life performance, offering high wear resistance in the tip area. Robust construction supports repeated use in a busy workshop environment.
Fewer replacements and steady performance mean dependable centre punching over the long term, suitable for regular workshop tasks.
