The AGEMA Technologies

Two Technologies – One Machine

Erosive Hole Drilling

Die Sinking

The AGEMA Start Hole Drilling Machines combine both technologies, the erosive hole drilling and die sinking, on one machine.

Electrical Discharges

Our AGEMA EDM Machines use electrical discharges to achieve a thermal abrasion on the workpiece surface without damaging the micro structure.

Hole Drilling as technology enables

We are happy to offer trials on your workpieces or test processings. You can also schedule an appointment for a personal or video call visit at our demonstration and test center.

  • Start holes: electrode diameters from 0.30 up to 10.00 mm

  • Fine drill holes: electrode diameters from 0.06 bis 0.30 mm

  • Functional drill holes, also at an acute angle to the workpiece axis

  • precision drill holes in carbide and steel with a proven minimal damage of the material

  • high accuracy of the drill holes (position, straightness, cylindricity)

  • high ablation speed

Die Sinking

AGEMA Machines are also suitable to perform die sinking applications

  • planetary deviation for expansion, e.g. manufacturing of fittings

  • thread sinking in carbide and steel on the basis of predefined technologies e.g. M3 to M8

  • realisation of a variety of roughness levels in the sinking process

Work Piece Materials

The AGEMA Maschines can process all electrically conductive materials:

coated materials

e.g. PCD, CBN


steel, stainless steel, special steel

Without microcracks!


any brass alloys.


all materials of porcelain and ceramics


all kinds of aluminium: whether pure aluminum, naturally hard or hardenable alloys.



Eroding Result

Through oil as dielectric we achieve highest precision and quality in our eroding result:

  • high process reliability in carbide due to years of process optimization and experience

  • non-destructive generation of drilling holes

  • realisation of a variety of roughness levels in the sinking process

  • minimal damage of the material due to low thermal impact in carbide, thus avoiding microcracks

  • high surface quality

  • optimum flushing effect within the drilling hole due to low-viscosity dielectric
