Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and extended lifespan. Featuring a Thunderbolt web design, these bits have a thicker core than standard drill bits, providing enhanced strength and protection against side-load breakage. The specially designed parabolic flute form ensures rapid chip clearance, while the 3-flat Secure-Grip shank firmly holds the bit in the drill chuck, preventing slippage during operation. The 135-degree split point tip facilitates precision starting and minimizes walking, allowing for fast and accurate hole creation. These bits are effective for drilling on curved surfaces and require less effort to penetrate materials such as metal, wood, and PVC. They are highly recommended for use with portable drills. The black oxide finish adds lubricity and serves as an anti-corrosive agent, making them suitable for general-purpose drilling in various applications.
