Our Milwaukee® Thunderbolt® 20 pc titanium drill bit set offers heavy-duty performance on the jobsite. Titanium coating reduces heat build-up and keeps the bit sharper providing up to 3x longer life. The thicker core provides ultimate strength and protects against side-load breakage while a specially designed parabolic flute form clears chips and debris fast to keep the bit cool. The 135° split point tip delivers a precision start 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 in Packout™. Milwaukee® 48-89-1105 Thunderbolt® Titanium Drill Bit Set, 20 pc
