Cobalt may be incredibly tough, but you need to treat the drill bits with care because if they are dropped or mishandled, they can become damaged and may need to be replaced. The strength of cobalt, when mixed with an alloy, means they can safely operate at high speeds for long periods, without the need for cooling or cutting fluids.Ĭobalt drill bits are corrosion resistant, which means if they are treated with care they can deliver long-term performance. Pan American Tools line of cobalt drill bits are made from heat-resistant, cobalt high-speed steel, with heavy-duty flute construction and a 135-degree split point. Cobalt has a melting point of 1495☌ and a boiling point of 2927☌, which makes it the ideal material for high RPM drilling. One of the strengths of cobalt is its ability to withstand high temperatures. Cobalt drill bits aren’t made from solid cobalt, but are a combination of steel and a percentage of cobalt – typically between 5-7%.
