The 20-Piece Milwaukeer Titanium coated Drill Bit Set offers convenience and heavy-duty performance on the jobsite. Milwaukee Titanium coated drill bits are designed for extreme durability and up to 3X longer life. The tapered web resists side-load breakage, while the the 3-Flat Secure-GripT shank holds the bit firmly in the drill chuck. The titanium coating reduces heat build-up and keeps the bit sharp to extend performance. The 135? split point tip delivers a precision start and prevents walking for fast, accurate holes.Effective for drilling on curved surfaces, Milwaukee Titanium Coated bits require less effort to drill through wood, metal and PVC, and are highly recommended for use with portable drills. 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".
