Drills
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.
Lances and knives
This section contains lances and knives for vhf cutting heads.
Diamond tools
We also offer CNC tools with cutting edges of polycrystalline diamond for milling and with monocrystalline diamond for polishing.
High-quality CNC tools, produced in house
Our tool specialists develop sophisticated cutting geometries to precisely design the tools for their use in a wide range of different materials with the optimal machining strategy.
vhf manufactures its CNC tools on modern six and seven-axis precision grinding centers. These guarantee optimal conditions for the production of complex milling tools of highest quality. For our tools, we exclusively use high-quality ultrafine grain or superfine grain carbide grades from German production. This means that you always get a carbide tool of absolute top-quality for your tasks that perfectly meets your requirements.
Order today, use it tomorrow
If you order your CNC tools by 12 noon, they are usually shipped the same day. In addition, our online shop stocks all the necessary consumables and important accessories for customers who already own a vhf milling machine. For all orders placed via the vhf shop, the delivery within Germany, the EU and Switzerland is free of shipping costs, for all other regions attractive shipping rates apply.
Over 1,000 different cutting geometries
So you can find the right CNC tool for every application. That not only gives you higher feed rates and greater durability, but also improves the finished surface of your workpieces.
You can rely on carbide tools
Their exceptional hardness, durability and rigidity make carbide tools vastly superior to those made of high-speed steel (HSS). Carbide tools from vhf are therefore ideally suited for high-speed cutting.
vhf diamond tools: developed by experts for experts
Diamond tools – at vhf these are CNC tools with a carbide shank and a diamond tip – are several times more durable and so the more cost-effective alternative for many machining tasks. In addition to their exceptional hardness, another major advantage of diamond tools is that they are suitable for dry machining and can be reground several times.
Coatings for additional longevity
Increase the working life of your CNC tools significantly by choosing a coated vhf carbide tool. vhf offers you a wide range of alternative coatings to ensure you always get the best result for every application.

Tips for using your CNC tools
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:
- type of the material (with data sheet, where necessary)
- the maximum thickness which you want to process
- your intended tool diameter
- basic information concerning your machine (manufacturer and model, rotational speed of the spindle and its power, fixation of the workpiece)
Setting the machining parameters
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:
- Which material should be processed?
- How will the workpiece be fixed?
- Are cooling/lubrication or suction available?
- Which machine is in use (structure, rigidity)?
- What is the power and maximum speed of your milling spindle?
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.
Dipping depth
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:
- rigid foam: up to 4-fold diameter
- plastics (acrylic, etc.): up to 2-fold diameter
- aluminium: up to 0.5-fold diameter
- steel/stainless steel: up to 0.2-fold 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.
Choice of the milling direction
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.
- Up-cut milling: the tool runs against the material in the feed direction and increases the chip thickness from the entry of the cutting edge to the center.
- Synchronous milling: the tool runs in the feed direction with the material. This reduces the chip thickness from the entry to the exit of the cutting edge.
Examine your workpiece edge and the edge of the remnant. If necessary, the direction must be reversed.
Cooling the cutting edge of the tool
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.
What to do in case of problems?
| 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 |
