  • TiAIN Coating for Enhanced Performance: Featuring an industrial-grade TiAIN coating with exceptional hardness, these step drill bits deliver extended service life, higher processing speeds, and improved heat resistance. The coating also offers superior wear and corrosion resistance, strong adhesion, and reduced friction for smoother operation.
  • Premium M35 Steel Construction: Crafted from high-speed M35 steel, these bits effortlessly drill through a variety of materials—including stainless steel up to 3mm thick, and iron, aluminum, and other metals up to 5mm thick. The optimized conical design and deep double-flute helix ensure efficient chip removal and stable performance.
  • Comprehensive Size Range – Grade 15 (Ø4-32mm): This set includes diameters ranging from 4mm to 32mm in 2mm increments (4, 6, 8, 10… 32mm), making it ideal for pre-drilling, drilling, deburring, and other everyday metalworking tasks.
  • 10mm Drill Bit with Universal Shank: Specifically engineered for compatibility with cordless screwdrivers, drill guns, and bench drills, this 10mm bit features a 24mm shank length and a minimum torque capacity of 1100 Nm, offering both versatility and power in demanding applications.
  • Usage Tips: For best results, use cutting oil during initial operation to facilitate easier starts and reduce friction. Since drill bits are subject to wear, inspect them regularly and replace when significant wear occurs to maintain drilling precision and safety.
