Laser drilling: micrometre-precision drilling in all your materials

From a few microns to several hundred microns, cylindrical or tapered geometries, slots, access to the most difficult areas: IREPA LASER develops bespoke laser drilling processes.

Laser drilling: one process, several modes

Compared with mechanical drilling, there is no cutting force and, whatever the hardness of the material, the laser is not subject to tool wear.

Unlike EDM, the laser drills regardless of the material’s electrical properties. The case-by-case features of laser drilling are:

  • Diameter down to <10µm
  • High aspect ratio 1:50
  • Throughput / productivity

Metals, ceramics, composites: tailored laser drilling solutions

Drilling parameters must be adapted to each material and each drilling configuration, as the challenges differ depending on whether you are drilling titanium, ceramic or CFRP. The main families we work with are:

  • Metals and alloys: steel, aluminium, nickel, titanium…
  • Engineering polymers
  • Ceramics and glass
  • Composites (CFRP, CMC…)

Thanks to our mastery of laser–material interactions, we select the laser technology and adapt its parameters to guarantee precision, geometry and quality.

Comprehensive support for your laser drilling projects

Every laser drilling project begins with a precise definition of the surface property to be achieved. Here is our typical process.

Feasibility study and choice of laser parameters

Development and optimisation of patterns and textures

Trials and prototypes on real parts

Industrialisation and process transfer

Quality control and surface validation

Training in laser drilling

The new generation of pulsed lasers delivers performance that can place laser engraving in a strong position compared with traditional tools. Many applications are already operational in industry, particularly in watchmaking and even for the manufacture of injection moulds or dies

Our training courses enable you to :


  • Be able to adapt settings according to the laser technology.
  • Apply the basic principles of laser engraving and micro-machining.
  • Master the influence of operating parameters.
  • Acquire a process optimisation methodology.

Our training course aims to give you the skills to set up and optimise your engraving or micro-machining processes.

Your questions about laser drilling

What is laser drilling?

A precise process for producing micrometre-scale holes by vaporising or sublimating the material.

Which materials can be drilled?

Metals, alloys, polymers, ceramics, composites, glass…

What precision can be achieved?

From a few microns to several hundred microns, depending on the technology and materials.

Can laser drilling be industrialised?

Yes, with automated processes that guarantee repeatability and productivity.

What are the advantages over traditional methods?

No contact, no tool wear, access to difficult areas, complex geometries and respect for the material.
