⚡ At a Glance
- • Punch Precision: Consistent centre marks, dependable depth control for drill starts
- • Best for: DIYers, machinists and tradespeople who need accurate starter holes
- • Not ideal for: Heavy industrial work that requires specialised impact tools
Two-piece set of automatic centre punches, 130mm long and 12mm in diameter. High-carbon steel construction with an adjustable spring mechanism, suitable for wood, metal and glass.
Accurate starter marks - with an adjustable spring-loaded impact mechanism
A spring compresses under pressure and then releases a focused impact through a high-carbon steel tip, while tension adjustment changes the striking force. Knurled surfaces stabilise grip during each press, helping maintain a consistent centre mark.
Precise, repeatable marks make pre-drilling simpler and reduce drill-bit wandering, saving time when aligning holes.
Durable, workshop-ready build - with high-carbon steel and knurled handles
All-steel construction uses high-carbon steel for handles and internal parts, chosen for wear resistance and longevity. Deep knurling increases friction between hand and tool, improving control under greasy or dusty conditions.
Long service life and a secure grip mean fewer replacements and safer, steadier use on-site or in the garage.
One-handed operation and emergency utility - thanks to spring action and compact size
Automatic push action removes the need for a hammer, operating by a single-handed press that triggers the internal spring. Compact dimensions make the set easy to carry in a tool roll or pocket.
Quick, no-fuss marking speeds up repetitive tasks and adds an emergency option for breaking glass if ever required.
