This 170-piece HSS drill bit set is an indispensable addition to any workshop, whether you work professionally or regularly take on DIY projects. The set includes a complete range of drill sizes from 1.0 mm to 10.0 mm, with multiple pieces per size, so you always have a spare on hand for intensive use. Especially in the smaller diameters, such as 1.0 to 3.0 mm, extra pieces have been included because these wear out or break most often. The drill bits are made from high-quality high-speed steel and feature a titanium coating, making them more wear-resistant and better able to withstand heat when drilling in metal, wood, and plastic. Thanks to the ground spiral flute and self-centering tip, you can start drilling quickly and accurately without slipping, even on smooth surfaces. This makes the set ideal for a wide range of applications, from fine finishing work to heavier drilling in construction materials. The sturdy and well-organized storage case keeps the drill bits sorted and protected. With its compact size and durable finish, the case is easy to take to any job site and keeps the drill bits well organized. This set is highly suitable for anyone who often works with different materials and doesn’t want to keep searching for the right size. The combination of durability, precision, and completeness makes this a reliable choice for both professionals and demanding DIY users.
