Milwaukee THUNDERBOLT 21-PC Black Oxide Drill Bit Set

Milwaukee THUNDERBOLT 21-PC Black Oxide Drill Bit Set is engineered for extreme durability, heavy-duty performance, and long-lasting use. These drill bits feature a thicker core web than standard bits to protect against side-load breakage, providing increased strength for demanding tasks. The 3-Flat Secure-Grip shanks ensure a firm, wobble-free hold in drill chucks, enhancing precision during drilling. Designed with a special parabolic flute, these bits clear chips quickly, while the 135 split point tip allows for accurate holes with precision starts and less walking. The black oxide coating makes them ideal for use with portable drills on a variety of materials including metal, wood, and PVC, and they perform effectively even on curved surfaces. This set includes a comprehensive range of sizes to cover many drilling needs.Model Number: 48-89-2801
