Milwaukee SHOCKWAVE HSS-G Red Hex Impact Rated Drill Bit Set (10 Piece). This set features 10 impact-rated drill bits with a 1/4" hex shank, optimized for impact drivers. The Titanium Nitride coating efficiently dispenses heat, making the bits suitable for high-speed applications. The unique QUAD EDGE™ Tip combines a 135° split point for precise and fast drilling starts without walking, and four cutting edges that create smaller chips to prevent heat build-up for longer life. Variable flute geometry allows for faster material ejection, helping the bits run cooler and preventing burnout. An enhanced tapered web design strengthens the core towards the shank for increased overall flute durability. The set includes bits in sizes from 3mm to 10mm and comes with a convenient organizer case.
