Carbide Inserts Versus HSS

One of the main benefits of using carbide inserts versus high speed steel (HSS) is that carbide is able to withstand much higher temperatures. Some times carbide will allow the machine operator to permit faster speeds increasing productivity. Addtionally carbide inserts may leave a better finish when tested against HSS. Carbide is typically considered to be more brittle than other materials. This can result in more frequent chipping or breaking. To compensate for this most manufacturers make tools that allow for inserts that fit within an insert holder. This allows for easy replacement of the carbide inserts at low costs since the entire tool does not need to be replaced. Today the majority of mills, end mills and lathe tools utilize carbide inserts.
