Is carbide harder than cobalt?
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.Click to see full answer.

Also asked, which is harder tungsten carbide or cobalt? Scratch Resistance: While cobalt is harder than titanium, and therefore more scratch resistant, tungsten is still the hardest metal currently on the market. In simple terms, although cobalt and tungsten are both extremely hard metals, a tungsten ring will have a higher resistance to scratching. what is the best drill bit for hardened steel? Go to a hardware or home improvement store for a cobalt bit that is designed specifically for drilling through steel. You want a cobalt bit, as it’s a type of high-speed steel (HSS) that has more cobalt in it and is strong enough to cut through hardened steel. Considering this, are cobalt drill bits the best? Cobalt drill bits are best for the toughest materials, like cast iron and other metals that are particularly abrasive.Is Cobalt stronger than titanium?Hardness: As mentioned in the detailing of cobalt and titanium’s scratch resistance, both metals have a similar hardness. But it was noted that cobalt was just a bit harder than titanium. However, the harder a metal, the less malleability it exhibits.
