THUNDERBOLT™ Black Oxide Drill Bit Set – 21 Pieces

Our MILWAUKEE® THUNDERBOLT® Black Oxide 21-piece drill bit set delivers strong performance on the jobsite. The black oxide coating reduces heat buildup and offers corrosion resistance. The thicker core provides ultimate strength and protects against side-load breakage, while a specially designed parabolic flute shape quickly clears chips and debris to keep the bit cool. The 135° split point provides precise starts and prevents walking for fast, accurate holes. MILWAUKEE® THUNDERBOLT® titanium coated bits are ideal for various drilling applications in wood, plastics, and metals. The set is organized in a customizable accessory case designed for use with PACKOUT™.
