Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and extended lifespan. The 9/64" drill bit features a Thunderbolt web design with a thicker core than standard drill bits, providing enhanced strength and protection against side-load breakage. Its specialized parabolic flute form efficiently clears chips and debris, maintaining a cooler drilling temperature. The precision start, 135-degree split point tip ensures immediate engagement upon contact, preventing walking and enabling fast, accurate hole creation. This drill bit is particularly effective for general-purpose drilling in wood and metal and excels in applications on curved surfaces. It requires less effort to drill and is highly recommended for use with portable drills. The black oxide coating adds lubricity and acts as an anti-corrosive agent, enhancing the bit's performance and longevity.
