Straight flutes drill shallow and horizontal holes in cast iron, and non-ferrous and hardened materials * Carbide resists wear better than high-speed or cobalt steel and withstands high speeds * Uncoated (bright) finish is an untreated surface that can be used on a range of materials * Self-centering 140-degree 4-facet point provides strength and high accuracy to penetrate material more easily than a conventional point, and produces small chips to reduce clogging * Round shank accommodates most drill chucks
