Milwaukee® Thunderbolt® titanium coated drill bits are designed for extreme durability and up to 3X longer life. The thunderbolt web features a thicker core than a standard drill bit to provide ultimate strength and protect against side-load breakage. The titanium coating reduces heat build-up and keeps the bit sharp to extend performance. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. Effective for drilling on curved surfaces, Milwaukee® Thunderbolt® titanium coated bits require less effort to drill through wood, metal and PVC, and are highly recommended for use with portable drills. Includes two bits.
