Milwaukee THUNDERBOLT™ 15-PC Black Oxide Drill Bits are expertly designed to make drilling through metal, wood, PVC, and curved surfaces easier and more efficient. Featuring a durable black oxide coating, these drill bits resist corrosion to ensure long-lasting performance. The thicker core web provides added strength to prevent side-load breakage, while the specially engineered parabolic flute quickly clears chips for smoother drilling. With a 135° split point tip, these bits start drilling immediately upon contact, reducing walking for precise results. The 3-Flat Secure-Grip™ shank keeps the bit firmly in place within the drill chuck, enhancing control and stability. This set includes a variety of sizes and comes in a sturdy hard case, making it highly for use with portable drills. Model Number: 48-89-2803
