- The Milwaukee® 23-piece cobalt RED HELIX™ drill bit kit is engineered for extreme durability and long life in hard metal applications. The drill bits are designed with variable helix featuring an aggressive 35 deg helix angle ending at 15 deg. This allows for rapid chip removal, limiting heat buildup to stay sharper longer. The 135 deg split point bit tip delivers a precision start and prevents walking for fast, accurate holes. The heavy duty drill bits are ideal for tough applications and provide up to 10X life vs black oxide drill bits. The bit in the kit can be used in all twist drilling applications.
