Applications in steel construction
Peddinghaus lever punches produce round holes in flat and strip steel via a hand lever that transfers the punching force to punch and die. They are used wherever individual holes are made without drilling, for example for bolted connections or fittings. Punching works without chip removal and leaves a clean hole pattern.
Typical applications
- Making individual holes in flat and strip steel without drilling
- Preparing hole patterns for bolted connections
- Punching fittings, straps and angles
- Chipless working in the workshop and mobile on the construction site
- Fast punching of thin steel cross-sections in single and small-batch production
Which businesses use it
Used in locksmith shops, in metal and structural fabrication and in assembly operations that make individual holes without a drilling machine.
Frequently asked questions
How does a lever punch work?
A hand lever brings punch and die together and punches through the material without chip removal. A round hole is produced without the need to drill.
When is punching more sensible than drilling?
When making individual holes in thin flat steel, punching is faster, works without chips and without heat input. For bolt holes in straps and fittings this is often the quicker solution in practice.
Which material can be punched with the lever punch?
It is designed for thinner flat and strip steel cross-sections. Hole diameter and material thickness depend on the punching force of the respective model.
