Milling Cutters Materials

There are many cutting procedures that are best suited to certain situations. Because of the differences in methods and environments, different milling cutter materials are required. The following are the most frequent materials used to manufacture milling cutting tools.

Carbon Tool Steel

This is a low-cost metal with good machinability for creating mill-cutting tools. This material typically contains 0.6-1.5% carbon and less than 0.5% manganese and silicon. Depending on the grain size and hardness desired by the maker, it may additionally incorporate metals such as chromium and vanadium.

Because of its great wear resistance, milling cutters manufactured of carbon tool steel keep their cutting edge for a long time. However, at temperatures exceeding 250°C, the hardness of this material rapidly decreases. This makes it perfect for the production of low-speed machining tools such as twist drills, milling tools, and forming and turning tools. It's also perfect for cutting soft metals like magnesium, aluminum, and brass.

High-Speed Steel (HSS)

This is carbon steel with a minor quantity of molybdenum, tungsten, chromium, and other alloying elements that distinguishes it from standard carbon steel. High-speed steel gains toughness, wear resistance, and hardenability with the addition of these alloys, resulting in a higher metal removal rate.

Manufacturers utilize both re-sharpening and coolants to extend the life of this tool (since it loses hardness at temperatures above 650°C). This mill tool material is perfect for the manufacture of drills, broaches, and single-point lathe-cutting tools.

Cemented Carbide Tool and Cermet

This mill tool made using powder metallurgy technology is highly robust and can endure high-speed cutting operations. This substance, which is made of tungsten, titanium carbide, and tantalum, can withstand temperatures of up to 1000°C. Manufacturers employ several binders to bind the elements of this instrument, which include cobalt, nickel, and molybdenum.

Cermet is a tool used for diverse finishing and semi-finishing milling operations on various materials, including alloy and stainless steel, where the binding ingredient includes nickel and molybdenum. Tools with low cobalt content, on the other hand, are better for finishing operations, while high-cobalt tools are best for rough cuts.


This substance is non-reactive and more durable than cermets. It also has superior heat resistance, wear resistance, and tear resistance than carbides. Because of their high heat resistance, ceramic milling cutters are perfect for milling super alloy workpieces. High heat is essential for ceramics to perform well in hard materials.


This is a non-ferrous alloy substance that can only be created through grinding or casting. It contains varying amounts of chromium and cobalt. It could also have tungsten or molybdenum in it. This material's cutting edges keep their quality even at extremely high temperatures and speeds.

On larger cutters, stellite teeth are attached to a steel disk; on smaller cutters, solid stellite is used. Stellite cutters are perfect for mass-producing vehicle engine castings and other parts.
