Product Details
The RED HELIX Cobalt 7/16" Drill Bit is engineered for extreme durability and longer life in hard metal applications. It features a VARIABLE HELIX design with an aggressive 35-degree helix angle that transitions to 15 degrees, enhancing drilling efficiency. The QUADEDGE TIP reduces heat buildup, allowing for faster drilling. The 135-degree split point tip ensures a precision start and prevents walking, making it suitable for fast, accurate holes in hard metal, PVC, and wood. The drill bit is constructed with a new ENHANCED TAPERED WEB that strengthens the core, increasing flute durability. These cobalt twist drill bits are specifically designed for challenging applications, providing up to 15 times the life compared to Black Oxide Drill Bits. The Thunderbolt core is engineered to resist breaking, ensuring reliability during use in specialty drilling tasks, particularly in hard metals such as stainless steel, and are excellent for use in cordless drills.
