Milwaukee® COBALT RED HELIX™ drill bits are engineered for extreme durability and long life in hard metal applications. Designed with a variable helix ™ that includes an aggressive 35. helix angle which ends at 15., the cobalt bits with RED HELIX™ provide Rapid Chip Removal™ limiting heat buildup to Stay Sharper Longer™. The 135. split point tip delivers a precision start and prevents walking for fast, accurate holes. Ideal for tough applications and provide up to 10X life vs. Black Oxide Drill Bits™ but can be used in all twist drilling applications.
