Milwaukee 15/64" Thunderbolt Black Oxide Drill Bit
Description
The Milwaukee Thunderbolt 15/64" Black Oxide Drill Bit is a jobber-length twist bit built for extreme durability and long life in demanding drilling applications. Milwaukee engineered the Thunderbolt to outlast standard drill bits through a reinforced core structure, a specialized surface coating, and precision cutting geometry. The bit measures 6.0 inches in overall length with a 4.0-inch flute length and a 0.25-inch shank diameter, sized to fit standard chucks on most portable drills. Curved and irregular surfaces demand extra accuracy, and the Thunderbolt geometry makes correct positioning noticeably easier while reducing the force needed to drill. Milwaukee recommends this bit for portable drill applications where accurate starts and long bit life matter most on the job.
