The Milwaukee Thunderbolt black oxide jobber length drill bit is a general-purpose drill bit engineered for durability and precision in wood, metal, and PVC. The Thunderbolt web features a thicker core than standard drill bits to provide ultimate strength and protect against side-load breakage. This robust construction makes it ideal for both portable and cordless drills, delivering reliable performance across diverse drilling applications.
The 135-degree split point tip delivers precision starts with no walking, enabling fast and accurate hole placement. The specially designed parabolic flute form clears chips efficiently during drilling, reducing friction and effort. The 3-flat Secure-Grip shank holds the bit firmly in the drill chuck, preventing slipping and ensuring consistent performance. Black oxide coating adds lubricity and provides anti-corrosive protection, extending bit life even in demanding conditions.
