Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and long life, specifically designed for general-purpose drilling in wood and metal. The 11/32" drill bit features a Thunderbolt web, which incorporates a thicker core than standard drill bits, providing enhanced strength and protection against side-load breakage. Its specially designed parabolic flute form efficiently clears chips and debris, ensuring the bit remains cool during operation. The precision start is facilitated by a 135-degree split point tip that begins on contact, preventing the bit from walking and allowing for fast, accurate holes. This drill bit is particularly effective for drilling on curved surfaces, requiring less effort and is highly recommended for use with portable drills. The black oxide finish adds lubricity and serves as an anti-corrosive layer, further extending the bit's longevity and performance in various applications.
