The 20-Piece Milwaukee® Titanium coated drill bit set is designed for extreme durability. The tapered web resists side-load breakage, while the the 3-Flat Secure-Grip™;;; shank holds the bit firmly in the drill chuck. The titanium coating reduces heat build-up and keeps the bit sharp to extend performance while the 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. The set comes in a resilient case and includes bit sizes (2) 1/16", (2) 5/64", (2) 3/32", (2) 7/64", (2) 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 1/4", 5/16", 3/8", and 1/2".
