Product Details
Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and long life, featuring a Thunderbolt web that incorporates a thicker core than standard drill bits, providing enhanced strength and protection against side-load breakage. The drill bits are designed with a specially formulated parabolic flute that efficiently clears chips and debris, maintaining cooler operational temperatures. The precision start is facilitated by a 135-degree split point tip, which allows for immediate engagement upon contact, preventing the bit from walking and ensuring fast, accurate hole drilling. These drill bits excel in drilling applications on both wood and metal surfaces, are particularly effective when used with portable drills, and their black oxide coating adds lubricity and serves as an anti-corrosive barrier, enhancing overall performance and longevity.
