whirling knives

Ideal for ultra-fine threads

We offer special whirling knives for the production of fine and superfine threads. These have proven themselves especially for the machining of titanium in medical technology, e.g. our vortex knife sets for the production of dental and bone screws according to DIN 588 HA 1.5 / HA 2 / HA 2.7 / HA 3.5 / HA 4.5 - HB 4 / HB 6.5.

In addition, we also offer two-threated tools. All tools are precision ground and polished. We also offer double-threat chasing tools. In addition, we also offer you two-toothed chasing tools. All tools are precision ground and lapped.

As an alternative to our whirling knives, we also manufacture triangular plates for the whirling heads commonly available on the market with multiple inserts, either as single or double thread chasing inserts

Perfect precision and strong service

Due to the high dimensional accuracy and perfect change accuracy of our tools, set-up times during production are considerably minimised. This allows you to significantly increase your machine productivity. In addition to a 24-hour resharpening service, we offer our customers an in-house coating service. Permanent quality control of the coating thicknesses and the documentation of the batches run are part of our quality assurance. In-house coating enables us to achieve the shortest possible delivery times, enabling our customers to carry out short-term trials with different coatings.
