The Exact 07014 HSS Step Drill Set is a three-piece drill set designed for metalworking applications. This precision tool set, made in Germany, includes drills with diameters of 4-12 mm, 4-20 mm, and 6-30 mm, all featuring a titanium nitride (TiN) coating for enhanced durability and wear resistance. The HSS construction (high-speed steel) ensures long-lasting performance when working with metal and plastic. Each drill has a three-flat shank for a secure grip in chucks and a cross tip for optimal centering during operation. The variable spiral flute geometry allows for a smooth cut, high cutting performance, and efficient chip removal. This step drill set is particularly suitable for countersinking holes, sinking screws, and deburring uneven edges on metal surfaces. The TiN coating reduces friction and heat generation during drilling, extending tool life. The set consists of three precision step drills that cover a comprehensive diameter range from 4 mm to 30 mm, making it versatile for various metalworking tasks. All components are packaged as a complete set and are ready for immediate use in professional workshops or industrial applications that require precise hole preparation and surface finishing.
