Large, versatile drill bits with a reduced 1/2" round shank. Constructed from a high-speed steel substrate. 118° radial point. Standard 6" overall length and 3-1/8" flute length for increased rigidity, less deflection, and improved hole accuracy. Standard lengths allow for minimal adjustment during tool changes in screw machines and machining centers. Ideal for portable drilling due to increased rigidity. The black oxide finish increases wear resistance and adds lubrication, improving chip flow. Use wherever the maximum chuck capacity is 1/2". For drilling carbon steel; suitable for steel, cast iron, and wood. Made in the USA. 30-day warranty.
