Thread polygoning cutter

With traditional machining, the production of micro-screws can be challenging and can represent a considerable production time.

With the 5000 series polygon milling cutters, standard or special profiles can be generated very quickly and in very high quality.

It will only take a few seconds to obtain a perfect thread.

The innovations of Louis Bélet SA allow, among other things, to produce very fine, longer threads or by drastically reducing the vibrations and thus the facets induced by them.

The 5000 series polygon milling cutters are ground on our profiling machines designed and assembled by our teams. They enable us to produce perfect profiles while maintaining flexibility in terms of the size of the tool or the profile to be produced.


Polygon turning requires a synchronization of the spindles. Often, a dedicated tool holder for swiss machines is required.

The spindle of the 5000 polygon cutter and the workpiece must be driven at the same speed.

This means that Nmill = Npiece.

The thread is produced by driving into the material. No lateral movement is necessary and the screw is produced in a few seconds. The rotational speeds vary depending on the material to be machined.

Quality of surface finish

« The result obtained with your tools is similar or even better than traditional threading by turning! »

Here is a testimonial from a customer who uses our tools which makes us particularly proud of our achievements.

Indeed, the surface finish is often the obstacle that keeps customers from using this technology.

The attention paid to the production of the 5000 milling cutters as well as the singularity of our grinders make our technology meet the needs of the most demanding companies.


Innovation is in Louis Bélet's DNA. In order to maximize the longevity of our 5000 tools, a grinding principle has been developed by our R&D teams in order to double the life of this tool.

Once the critical wear of a face has been reached, you simply turn the tool over and continue your operation.

No more need for regrinding or worrying about the direction of rotation of the tool.

The 5000 Reverso series is completely neutral in this respect!

Custom made

The features of this 5000 polygon tool can be customized to your needs. Initially imagined for the watchmaking field, these tools quickly became the reference for the realization of screws in large volumes in various fields such as medical or precision connectors.

Pitches between S0.30 and S1.4 mm for tool diameters of 40 or 45 mm are available as standard. Profile and pitch dimensions or dedicated tool diameter are as many possibilities as we can offer for these tools. Do not hesitate to challenge us!
