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?
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
Ungewöhnlich hoher Werkzeugverschleiß
- Check material composition
- Check collet chuck/replace if necessary
- Adjust parameters
- Check machine
CNC tools: developed by experts for experts
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
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.

Frequently asked questions and answers about vhf tools
When selecting and using tools, many questions arise regarding cutting geometries, coatings, suitable materials, or machining parameters. Below you will find the most important questions and answers on these and other topics:
What are the advantages of using original vhf tools?
vhf tools are made exclusively from high-quality ultra-fine grain or super-fine grain carbide grades manufactured in Germany. After being manufactured on our state-of-the-art six-axis precision grinding centers, they undergo strict quality controls. They are primarily solid carbide tools or diamond-set solid carbide shanks, which are characterized by a particularly long service life. With over 1,000 cutting edge geometries and numerous hard coatings, you will find the right tool for every material and every application.
Our tool specialists have perfectly matched vhf tools to the requirements and typical areas of application of vhf machines. Of course, vhf tools are also ideally suited for use in third-party machines. We regularly test the quality of our tools in practical use. At vhf, we use our own tools to manufacture numerous machine parts for our CNC milling machines in-house. As a result, we not only check the production quality, but also have our own incentive to constantly optimize our tools.
What materials are single tooth cutters used for?
The large flute on single-tooth milling cutters enables easy plunging into the material and ensures that the chips are removed more easily. The single-tooth cutter has a clear advantage, particularly with plastics (e.g. PVC or acrylic glass) and some non-ferrous metals (e.g. aluminum), as the problem of cutting edge erosion is less of a problem than the risk of clogging due to chips.
vhf offers a selection of single tooth cutters that is unparalleled on the market. For example, there are tools with left-hand or right-hand twist, tools with or without coating and a huge selection of cutting edge and shank diameters – all developed and manufactured by vhf. And to ensure that you are guaranteed to find the right tool for every application, our expert tool consultants will be happy to help you.
When are double- or multi-tooth cutters recommended?
The more cutting edges a milling cutter has, the more the open space decreases, but at the same time the wear is distributed over several cutting edges, which increases the tool life. The milling cutter also runs smoother. A double-tooth milling cutter is well suited for machining harder non-ferrous metals such as brass and harder types of aluminum. We recommend multi-tooth cutters for fiber-reinforced materials and highly abrasive materials such as ferrous materials.
When is it advisable to use coated tools?
Hard coatings are generally used to improve the service life and performance of tools. They are often used in metalworking, especially when machining hard materials such as steel, cast iron or titanium. vhf offers several strong coatings for various applications with the STRATUM series.
A coating offers several advantages: The tool life is extended as the cutting edges are protected from wear. In addition, coated tools often improve the surface quality of the machined workpiece as they have a lower risk of wear marks or chipping.
However, as a coating also minimally rounds off the cutting edges, the sharpness of the cutting edge decreases slightly, which is why it is recommended to use uncoated tools for materials such as acrylic glass.
When are carbide tools used and when are diamond tools used?
Due to their outstanding hardness, wear resistance and toughness, carbide tools are far superior to those made of HS steel (HSS). This means that vhf tools made of solid carbide are ideally suited for HSC milling (High Speed Cutting). In addition to the large selection of carbide tools, vhf also offers diamond tools. These offer a multiple of tool life and are therefore the more economical alternative for many machining tasks. Another advantage of diamond tools is that they can be re-sharpened several times.
Why are there so many different tool geometries?
vhf offers so many different tool geometries for milling tools because they are each optimized for different applications and materials. Each tool geometry has specific properties that affect cutting force, surface quality, chip formation and tool life. Different materials require different tool geometries in order to achieve optimum results. For example, machining aluminum requires a different tool geometry than machining steel or plastic.
The different work steps also require different tool geometries. For example, there are special tools for roughing, finishing, contour milling, slot milling, thread milling, engraving, drilling, deburring, etc. The cutting conditions such as cutting depth, feed rate and cutting speed also influence the choice of suitable tool geometry. In addition, the tool geometry influences the way in which the chips form and flow away. A suitable tool geometry can make a significant contribution to improving chip formation and facilitating chip evacuation. It also has an influence on the surface quality of the machined workpiece.
