Milwaukee 48-89-2528 12.5mm Cobalt RED HELIX Twist Drill Bit

Description

Built for extreme performance in tough metals, the 12.5mm Cobalt RED HELIX™ Twist Drill Bit delivers exceptional strength, speed, and longevity. Its advanced variable helix design—transitioning from a 35° to 15° angle—promotes fast chip evacuation, lowers heat buildup, and helps maintain a sharp cutting edge. The precision-ground 135° QUAD EDGE™ split point enables accurate, no-walk starts for clean, consistent holes. Four cutting edges produce smaller chips for smoother drilling and reduced friction, while the reinforced taper web enhances core strength to resist breakage.
