Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and longevity. The drill bit features a thunderbolt web design, which includes a thicker core than standard drill bits, providing enhanced strength and resistance to side-load breakage. It incorporates a specially designed parabolic flute form that efficiently clears chips, facilitating smoother drilling operations. The 3-flat Secure-Grip shank ensures a firm grip within the drill chuck, minimizing slippage during use. The 135-degree split point tip allows for precise starting and prevents walking, enabling the creation of fast, accurate holes. These drill bits are effective for drilling on curved surfaces and require less effort to penetrate materials such as metal, wood, and PVC. Thunderbolt black oxide bits are particularly suited for use with portable drills, adding lubricity and exhibiting anti-corrosive properties.
