  • 50 Sizes: The step drill bits set includes 5 standard bits that can replace 50 individual drill bits and an automatic center punch. Please mark the spot that you are to drill for easier drilling
  • Titanium Coating: Our high-speed steel drill bits, fortified with a titanium coating, offer exceptional durability and maintain sharpness even through demanding tasks. The titanium coating increases wear resistance and minimizes friction, resulting in cooler operation.
  • PRODUCT Design: The split point tip, set at a 118-degree angle, significantly enhances wear resistance, making the drill bits long-lasting and efficient. The innovative two-flute design facilitates smoother cutting and enables easy evacuation of material particles, promoting cleaner and more precise drilling operations.
  • WIDELY Application: Perfect for home repairs and light jobs such as drilling holes in plastic, aluminum, copper, iron, and many other types of sheet metal(recommended to add coolant or water when drilling metal plates and the speed should not be too high).
  • CONVENIENT Storage: All the bits come in a well-organized case for easy transport and storage.
