Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials. It's used mostly for production drilling where a high-quality tool holder and equipment is used.

What Makes Cobalt Different from HSS? Cobalt steel is a variation of high speed steel with a higher content of cobalt. Common grades are M-35 and M-42, having 5% and 8% respectively. These steels are ideal for cutting tools because they have a high red hardness that gives it much higher heat resistance. This allows tools made of cobalt to be run at faster speeds and higher
