Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and longevity, making them ideal for general-purpose drilling in wood and metal. The 9/32" drill bit features a Thunderbolt core that boasts a thicker design than standard drill bits, providing enhanced strength and resistance to side-load breakage. Its specially designed parabolic flute form efficiently clears chips and debris, maintaining a cooler bit during use. The precision start is facilitated by a 135-degree split point tip, which ensures fast starts without walking, allowing for accurate hole placement. This drill bit is particularly effective for drilling on curved surfaces and requires less effort, making it highly suitable for use with portable drills. The black oxide finish adds lubricity and serves as an anti-corrosive layer, further enhancing the bit's performance and lifespan.
