Milwaukee 48-89-2301 1/16in Cobalt RED HELIX Twist Drill Bit

Description:

The 1/16 in. Cobalt RED HELIX™ Twist Drill Bit is built for maximum strength and reliable performance when drilling tough metals. Its advanced variable helix design transitions from a 35° aggressive angle to 15°, allowing faster chip evacuation, reduced heat buildup, and longer edge retention. The 135° QUAD EDGE™ split-point tip delivers accurate, no-walk starts for clean and precise holes. Four cutting edges create smaller chips for smoother removal, helping control heat and extend bit life. A reinforced internal taper web adds extra durability to resist breakage, while the cobalt construction provides up to 10X longer life than standard black oxide bits—making it ideal for demanding twist-drilling applications.
