Carbide milling inserts and high-speed steel inserts are two common types of cutting tools used for machining operations. Both types of inserts have their pros and cons, so it can be difficult to determine whether one is better than the other. To help you decide which type is best for your application, we’ve put together a comparison of the two.
High-speed steel inserts are composed of a blend of metal alloys such as molybdenum, tungsten, and cobalt. They are very strong and can withstand high temperatures, making them ideal for high-speed machining applications. However, they are not very wear-resistant and can quickly become dull when used for longer periods of time.
Carbide milling inserts are composed of a combination of tungsten carbide and cobalt. They are harder and more wear-resistant than high-speed steel inserts, making them better suited for operations involving high cutting speeds and feeds. They also require less sharpening than high-speed steel inserts, so they can be used for longer periods of time without needing to be replaced. However, they are more brittle than high-speed steel inserts and can be damaged if they are not used properly.
In conclusion, for most applications, carbide milling inserts are better than high-speed steel inserts. They are harder and more wear-resistant, so they last longer and require less sharpening. However, they are also more brittle than high-speed steel inserts, so they need to be used carefully. Ultimately, the best insert for your application will depend on the type of material you are machining and the operating conditions.
