• Longer life - titanium-coating reduces heat build-up for up to 3X longer life Extreme durability - thicker web provides greater strength Fast, accurate drilling - 135 deg split point tip starts on contact to prevent walking, while the parabolic flute clears chips fast Corrosion-resistant - titanium-coating keeps the bit sharp and provides added protection from heat build-up Versatile - reduced shank diameter for use in 3/8 in chucks

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 deg 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.
