Detailed Description:

The Milwaukee 48-89-2803 15-Piece Thunderbolt Black Oxide Drill Bit Set is a high-quality set of jobber length drill bits designed for durability and long life. The Thunderbolt web features a thicker core than standard drill bits, providing ultimate strength and protection against side-load breakage. The specially designed parabolic flute clears chips and debris quickly to keep the bit cool, while the precision start 135 Split Point tip prevents the bit from walking for fast, accurate holes. These drill bits are excellent for drilling on curved surfaces, require less effort, and are highly recommended for use with portable drills. The 3-Flat Secure-Grip shank ensures the bit won't slip in the drill chuck, and the reduced shank diameter is compatible with 3/8-Inch chucks.
