They are manufactured to Aerospace Standard 907 and have a high red hardness, making speeds up to 30% higher than conventional M2 high speed steel. Cobalt drill bits have a self-centering 135 degree cross point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118 degree point. Cobalt steel provides longer life compared to high speed steel drill bits and maintains the toughness and hardness of the tool at high drilling temperatures. A gold oxide coating acts as a lubricant and provides wear resistance, and the round shank fits most drill chucks. This drill bit set comes in a unique round drill index that combines form and function in a beautifully designed, easy-to-carry drill set. The shatterproof, water-resistant case fits easily anywhere you need it. Effortlessly grab the set in one hand like a travel coffee mug, leave it in your truck's cup holder while you're on your way to work, or hang it on your belt when all hands are on deck.
