Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and longevity in general-purpose drilling applications in wood and metal. The 5/32" drill bit features a Thunderbolt web that 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, maintaining optimal cooling during use. The precision start is facilitated by a 135-degree split point tip, which ensures immediate engagement upon contact, preventing the bit from walking and enabling fast, accurate hole drilling. This drill bit excels on curved surfaces, requiring less effort to operate and is highly recommended for use with portable drills. The black oxide finish adds lubricity and serves as an anti-corrosive agent, enhancing the bit's performance and lifespan.
