Are titanium drill bits better than black oxide?
Compared to titanium drill bits, both black oxide and cobalt drill bits are better. In addition to being non-corrosive, durable, and fast like titanium bits, cobalt and black oxide bits can be re-sharpened. While titanium drill bits have more or less the same uses as black oxide, the latter is much cheaper.
Is cobalt or titanium stronger?
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. As a result, it is able to have a much higher polish applied. However, the harder a metal, the less malleability it exhibits.
What is the hardest drill bit for metal?
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.
