laser precision drilling - blazingly fast with minimal wastage

Drilling was one of the first material processing methods to use lasers. A first major industrial application was the drilling of watch bearing jewels. The laser enables micro-drilling in a wide variety of shapes and in almost any material. Whether circular or elliptical, square or star-shaped, there are almost no limits to the shapes of the drilled openings.

In addition to the wide range of possibilities, the high accuracy and reproducibility as well as the enormous speed, laser drilling has another central advantage: The tool 'laser' works virtually wear-free.


Laser drilling is a non-chipping process in which the material is heated, melted and vaporized. By means of the process gas, the removed material is blown out of the hole.

Pulsed lasers are often used, the energy input of which can be precisely regulated. In addition to a wide variety of shapes, holes with different depths can also be generated. This allows through-holes or blind holes with diameters of less than 5 µm, whose conicity can also be influenced by appropriate laser parameters.

Scope of Service

Depending on the intended drilling depth, the conicity of the hole and the processing speed, a distinction can be made between different processes in laser drilling.

With our laser equipment and contract manufacturing, we can offer you the following processes:

Single pulse method


Trepanning process

Of course, we will be happy to advise you on the selection of the most optimal process to realize laser drilling according to your ideas.

Application examples

Process variants

Flame cutting

As the name suggests, in the single-pulse process the laser creates a through-hole or blind hole with only a single laser pulse. The walls of the resulting hole are usually characterized by a conical geometry.

Since this process requires high pulse energy, it is primarily used when drilling a large number of holes in thin materials.

Typical products whose holes are drilled using this method are filter or vent elements.


The percussion process does not create a hole with a single laser pulse. Instead, several laser pulses hit one and the same position of the component in succession. The high pulse rate melts and vaporizes the material layer by layer.

The percussion process allows higher aspect ratios, i.e. very deep holes with very small diameters. In addition, the conicity can be defined very precisely and significantly harder materials can also be machined. However, the process is associated with longer processing times. Percussion drilling is used, for example, to drill nozzle holes.  

Trepanning procedure

Trepanning drilling is actually a combination of drilling and cutting. Depending on the material and material thickness, a single drill hole is first created using the single pulse or percussion method. The target diameter is then achieved by laser cutting. Depending on the relative movement between the laser beam and the workpiece, a wide variety of drilling geometries are possible. Furthermore, trepanning drilling allows different conicities up to parallel drill walls.

Thanks to the process gas used, the melted material is blown out via the outlet side of the bore.
