Original vhf tools are manufactured by a particularly quality-conscious supplier: ourselves. We develop and produce to the highest standards carbide and diamond tools for milling, cutting, thread milling, engraving, chamfering and more.
On this page, we introduce our versatile CNC tools and provide valuable tips on how to use them so that you can reliably process almost any material.

CNC tools on stock
We offer carbide tools with one to six cutting edges in more than 600 variants and with different kinds of coatings.
Gravers and engraver’s milling cutters for processing materials from plastics to stainless steel.
This tool is used for deburring, countersinking, chamfering of non-ferrous metals and plastics.
Available in eight different variants for chamfering edges or milling slots, characters and radii. These router bits are used for working on wood and plastics.
Available as thread whirling cutters or as combined circular thread cutters with drill.
For materials like plastics, non-ferrous metals, printed circuit boards or thermosetting plastics and thermoplastics. With shank diameters up to 6 mm and optional coating.
This section contains lances and knives for vhf cutting heads.
We also offer CNC tools with cutting edges of polycrystalline diamond for milling and with monocrystalline diamond for polishing.

Always choose a CNC tool that is suitable for your material. Please refer to the detailed descriptions of the tools and their fields of application in the vhf catalog and in our online shop.
You may also use the possibility of a personal advice on tools by phone or email. In order to be able to give you the most suitable recommendation, please give us some information about your application:
In order to be able to set optimum values for lowering speed, dipping depth, feed rate and rotational speed, a number of factors are important. It is not always possible to provide generally valid information on the tool parameters.
Take advantage of our personal parameter advisory service – by phone or email. Please provide us with the following information about your application and machine:
Our recommendations are empirical values, which should serve you as an aid and introduction. In any case, please observe all safety and protective regulations of your machine.
The dipping depth of the CNC tool depends on the power of your spindle and must be in relation to the feed rate and speed. When milling deeper grooves, it is recommended to choose lower removal rates at higher feed rates. The following guide values apply to the ratio of milling depth to cutting edge diameter:
Please pay particular attention to the load display of the spindle controller, especially for large tool diameters in difficult-to-machine materials such as stainless steel. Therefore, approach the specified dipping depth only step by step.
The choice of milling direction depends mainly on the design of the milling machine (portal milling machine or machining center). The material, the milling tool and the parameters also play a role. When milling a groove, there is always a leading and a trailing edge.
Examine your workpiece edge and the edge of the remnant. If necessary, the direction must be reversed.
When machining non-ferrous metals as well as steels, continuous cooling of the milling cutter during machining is essential to ensure both the durability of the CNC tool and the quality of the workpiece edge. For some plastics, cooling by compressed air can already help.
If cooling is not possible, the feed rate of the milling tool should not be set too low. The heat dissipation takes place here through the chip. Otherwise, there is the danger of excessive heat development in the material.
Problem | Possible solution |
---|---|
Melting of the material, sticking of the chips, heat problem | – Increase the feed rate – Decrease rotational speed – Reduce material removal if necessary |
Clogging of the tool’s flute | – Reduce chip volume through reduced material removal – Check suction – Use a tool with larger flute |
Burr formation on the workpiece edge | – Increase the feed rate – Decrease rotational speed – Increase cooling – Replace blunt tool |
Tool breaks off | – Adjust parameters – Reduce removal rate – Check collet chuck/replace if necessary – Check clamping and machine for vibrations |
Poor edge quality due to chatter marks | – Reduce the feed rate – Increase the rotational speed – Check collet chuck/replace if necessary – Check clamping and machine for vibrations |
Unusually high tool wear | – Check material composition – Check collet chuck/replace if necessary – Adjust parameters – Check machine |
