Description
A cobalt drill bit is a type of drill bit that is made from a high-speed steel alloy containing a significant amount of cobalt. The addition of cobalt to the steel composition enhances the drill bit’s performance and durability, particularly when drilling into hard materials such as stainless steel, cast iron, and titanium.
The main advantage of cobalt drill bits is their superior hardness and heat resistance compared to standard high-speed steel drill bits. The cobalt content increases the bit’s ability to withstand high temperatures generated during drilling, reducing the risk of overheating and prolonging the lifespan of the drill bit.
Cobalt drill bits also have excellent strength and wear resistance, allowing them to maintain their sharp cutting edges for longer periods. This makes them suitable for repetitive or heavy-duty drilling applications.
