  • 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.
  • PRO-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.
  • PREMIUM STEP BITS: Each unibit is constructed of industrial high-speed steel with a titanium nitride coating for durability and strength to punch and drill clean holes in materials like plastic, aluminum, wood, copper, stainless steel, and other types of sheet metal.
  • QUICK CHANGE: The 1/4-inch hex shank makes for easy, convenient, and quick stepper bit switches and is compatible with impact ready power tools.
