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 fast, while the 3-Flat Secure-Grip™ shank holds the bit firmly in the drill chuck. 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.
- 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
