Milwaukee 48-89-2329 1/2in Cobalt RED HELIX Twist Drill Bit

Description:

The Milwaukee 1/2 inch Cobalt RED HELIX™ Twist Drill Bit is engineered for superior performance and unmatched durability in hard metals. Its variable helix design, ranging from a steep 35° angle to 15°, ensures rapid chip evacuation, reduces heat buildup, and maintains edge sharpness for long-lasting use. The QUAD EDGE™ 135° split-point tip allows precise starts with no walking, while four cutting edges generate smaller chips for faster removal and smoother drilling. Reinforced with an enhanced internal taper web, this drill bit resists premature breakage and provides consistent strength. Its cobalt coating delivers up to 10× the lifespan of standard black oxide bits, making it ideal for demanding metalworking and construction tasks.
