1/2 in. Thunderbolt® Titanium Coated Drill Bit

Milwaukee® Thunderbolt® Titanium Coated Drill Bits are engineered for extreme durability and up to 3X longer life. The Thunderbolt’s thicker core provides ultimate strength and protects against side-load breakage. The titanium coating reduces heat buildup and keeps the bit sharper for longer performance. A specially designed parabolic flute form quickly clears chips, while the 3-Flat Secure-Grip™ shank holds the bit firmly in the drill chuck. The 135° split point delivers a precise start and prevents walking for fast, accurate holes. Effective in drilling on curved surfaces, Milwaukee Thunderbolt titanium coated bits require less effort to drill wood, metal, and PVC, and are highly recommended for use with portable drills.
