FEATURES:

• The step drill bits are made of high-performance HSS steel with a TiAlN coating, providing high surface hardness, wear resistance and long service life, even when working with demanding materials such as steel and stainless steel
• They are ideal for drilling holes of progressively increasing diameters in thin materials, such as sheet metal, tubes and profiles, without having to change tools
• Each step progressively enlarges the hole, while the next step helps remove burrs and finish the edges, ensuring precise and clean holes.
• In many cases, they allow drilling and countersinking in a single operation, reducing machining time
• Suitable for sheet metal up to 6 mm thick. Each step has a height of 6 mm.
• The three-flat shank ensures a secure grip in the drill chuck and reduces the risk of slipping during drilling
• Suitable for use with handheld drills and drill presses
