Tungsten carbide is approximately twice as stiff as steel, with Young’s modulus of approximately 530?700 GPa (77,000 to 102,000 psi), and is double the density of steel? Nearly midway between that of lead and gold. It is comparable with corundum (?-Al2O3) in hardness.
They all feature toughened and hardened steel shanks that provide strength. This prevents bending and reduces vibrations for improved tool life.
