Tapping threads yourself in laser-cut parts

With a thread tap you can easily make threads in laser-cut plastic parts. The most suitable material for tapping threads is POM (polyacetal) , because it is tough and strong. In your laser cutting drawing, place circles where the tapped holes should be located. You can then tap the laser-cut holes directly*.

How big do you actually draw the holes for the regular tap sizes? We have sorted it out for you:

* People familiar with metalworking may know that laser-cut holes in steel cannot be directly tapped. They are hardened by the laser and must first be pre-drilled. This is not the case with plastics. You can tap the lasered hole without pre-drilling.
