Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and extended lifespan. Each drill bit features a Thunderbolt web that incorporates a thicker core than standard options, offering enhanced strength and protection against side-load breakage. The specially designed parabolic flute form facilitates rapid chip and debris clearance, effectively maintaining cooler operating temperatures. A precision start, 135-degree split point tip ensures immediate engagement upon contact, preventing bit walking for quick and precise hole creation. These drill bits are particularly effective on curved surfaces, requiring minimal effort for drilling tasks. They are highly recommended for use with portable drills and are suitable for general-purpose drilling in wood and metal. The black oxide material adds lubricity and serves as an anti-corrosive agent, enhancing the performance and longevity of the bits.
