Solid Carbide Threadmills


Are you fed up with tap breakage and looking for a more reliable process?

Compared to general tapping, thread milling is a much more stable process, producing a higher quality finish. Whilst tapping can be significantly faster, for projects requiring a high degree of precision or for larger diameter threads then thread milling is the obvious choice.


At our core, we are committed to delivering excellence to our valued customers. That's why we have formed strategic partnerships with industry leaders, such as Louis Bélet and DC Swiss. Through these collaborations, we are able to provide unparalleled precision and create flawless threads, even under the most challenging conditions.

The DC Swiss range of carbide thread milling cutters and thread whirl cutters make easy work of through and blind holes for both left and right hand threads and are suitable for use on a stable CNC machine.

Louis Bélet supplies a range of standard threadmills in carbide or PCD and custom-made tools for the micromechanics sector, suitable for everything from watchmaking and medical to aerospace and automotive. Their special 5000 series thread whirling cutter, for example, is calibrated to compensate for the deformation on threaded parts, producing excellent quality results fast with a cycle time of around a second - even with tight tolerances, the resulting product is first-class.

Whether you’re experienced in thread milling and looking for superior tools to complement your existing systems or considering making the switch from general tapping, we have the knowledge and equipment to help.

The End Mill was an ideal choice due to the unusual shape and the need to have a small radius. They turned out great, and the surface finish is really good.
