Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and longevity. The 15/64" drill bit features a Thunderbolt web that incorporates a thicker core than standard drill bits, providing enhanced strength and resistance to side-load breakage. Its specially designed parabolic flute form effectively clears chips and debris, ensuring the bit remains cool during use. The precision start is facilitated by a 135-degree split point tip that initiates on contact, preventing the bit from walking and enabling the creation of 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, making it suitable for general-purpose drilling in wood and metal applications.
