Carbon is not magnetic, but carbide managed to be slightly magnetic due to the cobalt binder used to hold the carbon and tungsten together. This means that if you apply a magnet to a carbide end mill, you will feel a slight pull of magnetic attraction.

The tungsten content is generally 15-25%; and the solid carbide is sintered by a powder metallurgy process with tungsten carbide as the main body and cobalt or other bonding metal, and the tungsten content is generally above 80%. Simply put, all the alloy whose hardness goes beyond HRC65 can be called solid carbide.

Solid carbide end mills provide extreme cutting performance, long tool life, and excellent process safety when machining demanding parts and are suitable for aerospace, medical, mold, power generation, and other industries.

A Steel made of carbon and another alloy metallic element is known as carbide steel. Frequently known as tungsten carbide, a popular type of metal carbide. Harder materials, potentially up to 70+HRC, can be machined using carbide tools.
