Viking 1/4"-1-3/8" Ultra Bit #00711 Multi-Diameter #12 Step Drill Bit

The 1/4" - 1-3/8" diameter Viking Type 78-UB #00711 Ultra Bit Multi-Diameter Step Drill Bit has a unique dual flute design for cutting fast, clean holes that are accurate and burr-free. The enhanced flute design also rapidly removes chips, ensuring a longer bit life and reducing the possibility of binding. The split point on the tip of the Ultra-Bit is designed for faster penetration and prevents walking. The unique Gold Oxide coating reduces friction and heat for a smoother cut and helps extend the life of the tool. Ultra-Bit Step Drill bits feature a round shank with 3-Flats for a secure grip when used in drills with standard 3-jaw Jacob style chucks.
