Milwaukee 48-89-2516 6.8mm Cobalt RED HELIX Twist Drill Bit

Description

The 6.8mm Cobalt RED HELIX Twist Drill Bit is designed to deliver outstanding strength and high-performance drilling in tough metal materials. Its advanced variable helix flute design, transitioning from a 35° aggressive angle to 15°, improves chip evacuation, reduces heat buildup, and helps maintain long-lasting sharpness during heavy-duty applications.
