Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and extended life. The 7/16" drill bit features a thunderbolt web design, which incorporates a thicker core than standard drill bits to enhance strength and minimize the risk of side-load breakage. A parabolic flute form is specifically designed to clear chips efficiently, ensuring optimal drilling performance. The 3-flat Secure-Grip shank provides a secure hold in the drill chuck, preventing slippage during use. With a 135-degree split point tip, this drill bit enables precision starting and prevents walking, allowing for fast and accurate hole creation. The bit is effective on curved surfaces and is capable of drilling through metal, wood, and PVC with reduced effort. The black oxide finish adds lubricity and serves as an anti-corrosive agent, making it particularly suitable for use with cordless drills, enhancing overall drilling efficiency and effectiveness.
