Punches and dies – tooling for hydraulic and sheet metal punches

Punches and dies are the key wear parts in hydraulic punchers, busbar punchers and sheet metal punches. They define the hole diameter, shape and edge quality and must be matched to the material and application.

This category includes punch and die sets for round and slotted holes in steel, stainless steel, aluminium and copper or aluminium busbars – suitable for hydraulic and electro-hydraulic punchers as well as sheet metal punches.

What are punches and dies?

In punching, the punch is the cutting tool that drives the material into the die. The punch geometry defines the hole shape and size, while the die supports the material and receives the slug. Only correctly matched punch and die sets ensure accurate holes with clean edges and long tool life.

Typical applications of punch and die sets

hole patterns in doors, walls and mounting plates of enclosures
round and slotted holes in copper and aluminium busbars
replacing drilling in flat bars, angles and profiles
electrical installation, switchgear and general metalwork

Variants and geometries

round punches for standard diameters (e.g. cable glands)
slotted punches for elongated holes and adjustable joints
special shapes for rectangular or combined cut-outs (model dependent)

Selecting the right punches and dies

When selecting punch and die sets, pay particular attention to:

compatibility with your puncher or sheet metal punch
material type and thickness (steel, stainless, aluminium, Cu/Al busbars)
required hole diameters and shapes
expected tool life and required edge quality

This ensures that your hydraulic punchers and busbar punchers deliver precise, economical results over the long term.
