MILWAUKEE® Thunderbolt Black Oxide jobber length drill bits are designed for extreme durability and long life. The Thunderbolt web features a thicker core than a standard drill bit to provide ultimate strength and protect against side-load breakage. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. The 135 degree split point tip delivers a precision start and prevents walking for fast, accurate holes. Effective for drilling on curved surfaces, MILWAUKEE® Thunderbolt Black Oxide bits require less effort to drill through metal, wood and PVC, and are highly recommended for use with portable drills. Sizes 1/8" and smaller have 2 bits per card. 9/64" and larger are 1 bit per card.
- Fast, accurate drilling: 135 split point tip starts on contact to prevent walking, while the parabolic flute clears chips fast
- Extreme durability: Thicker web provides greater strength and longer life
- Corrosion resistant: Black oxide coating provides lubricity and resists corrosion of the bit
