What are carbide tips?

Carbide (or more specifically tungsten carbide and titanium carbide) is a very common material on any sort of cutting tool: For example saw blades lathe bits drill bits router bits and dental drilling tips are generally made of carbide Carbide is so popular in these sorts of tools because it stays sharper longer than most other materials Additionally some ball-point pens use carbide
