Dual cutting blade design: The HSS step drill bit set is designed with double cutting blades, which provides faster, smoother and accurate drilling
HSS Titanium Coating: Crafted from high-speed steel (HSS) and enhanced with a titanium coating, our drill bits deliver outstanding durability and retain sharpness, even under challenging conditions. The titanium layer boosts wear resistance, reduces friction, and ensures cooler operation
Versatile Hole Processing: Our set of five standard step drill bits covers a wide range of hole diameters, effectively replacing 50 individual bits. This design eliminates the hassle of switching between multiple bits, allowing you to drill various hole sizes to meet all your DIY needs
Size marking: The 118° split point tip can minimize friction and resistance during the cutting process, thereby improving cutting efficiency. The laser-etched size markings provide positioning assistance for precise drilling, making the operation more user-friendly
Wide Range of Applications: Ideal for drilling holes in plastic, aluminum, wood, iron, and various other types of sheet metal (it is recommended to add coolant when drilling metal plates, and the speed should not be too high). Suitable for home DIY, handymen, and professionals
