The 27/64-inch Cobalt RED HELIX™ Twist Drill Bit is designed for exceptional strength and reliable performance when drilling through tough metals. Its variable helix design, transitioning from an aggressive 35° angle to 15°, promotes fast chip evacuation, reduces heat buildup, and helps maintain a sharp cutting edge for longer use.
A 135° QUAD EDGE™ split-point tip delivers accurate, walk-free starts for clean and precise holes, while the four cutting edges break material into smaller chips for faster removal and improved efficiency. The reinforced internal web taper adds structural strength to resist breakage during demanding applications. Finished with a cobalt coating, this drill bit provides outstanding durability—offering up to 10 times longer life compared to standard black oxide bits. Built for heavy-duty drilling tasks, it delivers professional-grade results from Milwaukee Tool.
