The Disston Extreme 7pc Black Oxide Drill Bit Set is engineered for durability, precision, and efficiency across a wide range of materials and drilling tasks. Each drill bit is manufactured with high-speed steel and finished with a black oxide coating, which increases wear resistance, reduces friction, and extends the life of the bit. This makes the set a dependable choice for professionals and DIY users alike. This 7-piece set includes the most commonly used bit sizes, providing versatility for general-purpose drilling in materials such as wood, plastic, and soft metals. Whether you're working on construction projects, home repairs, or assembly tasks, this set is designed to deliver consistent performance. The drill bits are equipped with a 135° split point tip, which allows for faster starts and minimizes walking on the material surface. This feature ensures greater control and cleaner results, especially when precision is critical. The black oxide coating not only enhances bit strength but also helps dissipate heat, allowing for longer drilling sessions without compromising performance. All bits come in a compact and durable storage case, which keeps them secure, organized, and easy to transport between job sites or around your workspace.
