    Cobalt Drill bits are ground from solid cobalt alloyed high speed steel for superior drilling performance. The higher cobalt alters the material characteristics by increasing the hardness and high resistance to abrasion. This type of drill is suited to drilling materials that have high toughness and tensile strength, such as cast iron, bronze, weld seams and stainless steel.
