Milwaukee 1/2 in. Cobalt Jobber Drill Bit

Milwaukee 1/2 in. Cobalt Jobber Drill Bits are engineered for extreme durability and long life in hard metal applications. Designed with a Variable Helix that includes an aggressive helix angle, these RED HELIX bits provide rapid chip removal to limit heat buildup and stay sharp longer. The split point tip delivers a precision start and prevents walking for fast, accurate holes, while the chip breaker further reduces heat generation. Featuring a Secure-Grip shank to prevent slipping in the drill chuck, these bits deliver up to 10X the life of standard black oxide drill bits across all twist drilling applications.
