What is Tungsten Carbide Insert

Tungsten carbide insert is made from tungsten carbide powder and other binders, thanks to high precision and high reliability, tungsten carbide inserts have been widely used worldwide for improving productivity.

Tungsten carbide insert is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use tungsten carbide insert, as well as many lathe tools and endmills. In recent decades, though, solid-carbide endmills have also become more commonly used, wherever the application's characteristics make the pros outweigh the cons.

Mining and tunneling cutting tools are most often fitted with cemented carbide tips, the so-called "Button Bits". Only man-made diamond can replace the cemented carbide buttons when conditions are ideal, but as rock drilling is a tough job the cemented carbide button bits remain the most used type throughout the world.
