3/16" THUNDERBOLT® Black Oxide Drill Bit

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° 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.

• Corrosion resistant: Black oxide coating provides lubricity and resists corrosion of the bit

• Extreme durability: Thicker web provides greater strength and longer life

• Fast, accurate drilling: 135° split point tip starts on contact to prevent walking, while the parabolic flute clears chips fast

• Versatile: reduced shank diameter for use in 3/8 in. chucks
