Milling tools made of cermet
Milling tools made of cermet are cutting tools that are used for metalworking, especially for milling. "Cermet" is a combination of the words "ceramic" and "metal". It refers to materials that contain both ceramic and metallic components. This combination of materials offers an excellent balance between hardness and toughness, which makes milling tools made of cermet particularly wear-resistant and heat-resistant.
Cermet milling tools are particularly suitable for milling hard and abrasive materials and for applications where a high surface finish is required. They retain their cutting properties even at high cutting speeds, which leads to more efficient machining processes and longer tool life. The properties of cermet milling tools make them a popular choice for fine machining and finishing workpieces.
However, they can be sensitive to impact and shock due to their relative brittleness. Due to their higher cost, however, they may not be the best choice for one-off or small batch applications.

Milling tools made from HSSE (high-speed steel)
Milling tools made from HSSE (high-speed steel with cobalt alloy) are cutting tools that are used for metalworking. HSSE stands for"High-Speed Steel with Cobalt" and refers to a special type of high-speed steel (HSS) that is improved by the addition of cobalt. This alloy increases the heat resistance and wear resistance of the milling tools, making it particularly suitable for demanding milling work where higher cutting speeds and longer tool life are required.
Compared to a conventional HSS milling cutter, milling tools made from HSSE are more resistant to wear and retain their sharpness for longer. This makes them ideal for milling both soft and harder materials such as stainless steel, titanium alloys and other difficult-to-machine materials. They offer a good combination of toughness and cutting performance and are therefore versatile, from coarse milling work to fine machining. They are not particularly suitable for machining hard or abrasive materials, as they wear more quickly and have lower heat resistance than other milling tool materials.
Due to their performance and durability, HSSE milling tools are popular in many manufacturing industries. Milling tools made from high speed steel with cobalt alloy are a cost-effective option where tool life is less critical. They are used for a variety of milling operations, including peripheral milling, face milling, slot milling and profile milling.

Milling tools made of HM (carbide)
Carbide (carbide) milling tools are high-performance cutting tools for metalworking that are made from a carbide alloy. Carbide is also known as tungsten carbide (WC). It is a composite material made from fine particles of hard materials, typically carbides (such as tungsten carbide), bonded with a metal, usually cobalt (Co). This material combines the extreme hardness and wear resistance of the carbides with the toughness of the metallic binder, making carbide tools particularly resistant to wear and high temperatures.
Compared to tools made of high-speed steel (HSS) or HSSE (high-performance high-speed steel with cobalt alloy), carbide milling tools offer significantly higher cutting performance and a longer tool life. They enable higher cutting speeds during milling and are capable of efficiently milling even very hard materials such as hardened steel, cast iron, non-ferrous metals and various plastics. These milling tools are suitable for both rough and fine machining. However, due to their hardness, they are also more brittle and less flexible than HSS or HSSE tools. This makes them more susceptible to breakage in the event of improper handling or extreme loads.
Carbide milling tools are manufactured in a variety of cutters, including end mills, face mills, slot cutters and many other profiles optimized for specific machining processes and requirements. Their excellent performance makes them a preferred choice in modern manufacturing where precision and efficiency are critical.

These tools are characterized by their exceptional hardness, wear resistance and heat resistance. This makes them ideal for demanding milling work at high cutting speeds and temperatures.
Compared to coated or carbide-tipped tools, solid carbide milling tools offer greater precision during milling and a longer tool life. They are capable of efficiently milling a wide range of materials, including hardened steel, stainless steel, aluminum, plastics and composites. Due to their robustness and durability, these milling cutters are particularly suitable for high-speed machining (HSC) and dry machining where no coolant is used.
The range of solid carbide milling tools includes a wide selection of geometries and sizes, including end mills, ball nose end mills, torus cutters and many specialized profiles designed for precise and efficient machining operations. Their excellent performance makes solid carbide end mills a preferred choice in various industries where high demands are placed on machining quality and productivity. However, due to their high cost, they may not be the best choice for all applications. Especially when machining softer materials where other milling tool materials would suffice.

Milling tools made of PCD (polycrystalline diamond)
Milling tools made of PCD (polycrystalline diamond) are high-performance cutting tools that are used for milling extremely hard and abrasive materials. PCD is a synthetically produced material consisting of microscopically small diamond particles that are sintered under high pressure and high temperature in a metal matrix (usually cobalt). These diamond particles are polycrystalline, i.e. they consist of many small diamond crystals which together form an extremely hard and wear-resistant material.
The main advantages of PCD milling tools are their exceptional hardness and abrasion resistance, which makes them ideal for milling non-ferrous metals such as aluminum, copper as well as plastics, fiber-reinforced plastics (CFRP/GRP) and other abrasive materials. They offer an outstanding tool life and enable very high machining speeds during milling, which can lead to a significant increase in productivity.
PCD tools are characterized by their ability to produce extremely smooth surfaces during milling. This makes them particularly valuable for applications where a high surface finish is required without the need for reworking. Although PCD tools are more expensive to purchase than conventional milling tools, the costs are amortized by their long service life and the reduction in machine downtime due to tool changes.
Due to their specific properties, PCD milling tools are primarily used where high demands are placed on machining quality and efficiency.

How do I achieve optimum results when milling?
To achieve optimum milling results, it is important to choose the right combination of tool, machining strategy and machine settings.
- Tool selection: Choose the right tool for the material and the specific machining task. For rough machining, use roughing cutters that can efficiently remove large amounts of material. For fine machining and achieving a high surface quality, a finishing cutter with fine cutting edges and, if necessary, a special coating should be used.
- Tool geometry and coating: Pay attention to the tool geometry and coating, which should be matched to the material to be machined. Different materials require different cutting edge geometries and coatings in order to minimize wear and increase tool life.
- Cutting conditions: Carefully match the cutting speed, feed rate, depth of cut and infeed to the material and cutter type. Overly aggressive conditions can lead to tool breakage, while overly conservative settings can unnecessarily increase machining time and affect surface finish.
- Machine stability: Ensure that the milling machine is stable and vibration-free. Vibrations can impair the surface finish and shorten tool life.
- Cooling and lubrication: Use suitable coolants or lubricants to minimize heat generation and improve cutting performance. For some materials and machining processes, dry machining or the use of minimum quantity lubrication (MQL) can also be advantageous.
- Workpiece fastening: Ensure that the workpiece is securely and precisely fastened to prevent movement during machining.
- Inspection and maintenance: Regularly check the sharpness and condition of the milling tools and change them if necessary. Blunted or damaged tools can significantly impair the quality of the machining process.
