Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and long life, featuring a Thunderbolt web design that incorporates a thicker core than standard drill bits, providing enhanced strength and protection against side-load breakage. The specialized parabolic flute form is designed to clear chips quickly, ensuring efficient drilling. Equipped with a 3-flat Secure-Grip shank, the bit maintains a firm hold in the drill chuck, enhancing stability during use. The 135-degree split point tip allows for precision starting, effectively preventing walking and facilitating fast, accurate hole creation. These bits are particularly effective for drilling on curved surfaces and require less effort to penetrate materials such as metal, wood, and PVC, making them highly suitable for use with portable drills. The black oxide finish adds lubricity and serves as an anti-corrosive feature, ensuring longevity and reliability in general-purpose drilling applications.
