Application Scenarios

Perfect for metal fabrication shops, automotive repair, HVAC installation, electrical conduit work, and general industrial manufacturing. Ideal for drilling precise stepped holes in mild steel, stainless steel, aluminum, copper, and other non-ferrous metals. Suitable for use with corded drills, impact drivers, and drill presses.

Core Performance

This step drill combines HSS durability with TiN coating technology to deliver 30% longer tool life compared to uncoated alternatives. The spiral flute design reduces cutting forces by 25%, minimizing operator fatigue while increasing drilling speed. The precision-ground point ensures accurate hole placement with less than 0.1mm deviation, even in hard materials up to 10mm thickness.

Quality Assurance

Manufactured to ISO 9001 standards with rigorous quality control at every stage. Each drill undergoes hardness testing (58-62 HRC) and dimensional inspection to ensure consistency. Backed by our 1-year warranty against manufacturing defects.

Differentiation

Unlike standard two-flute step drills, our spiral flute design provides superior chip evacuation, reducing clogging and heat buildup. The TiN coating offers better wear resistance than TiAlN alternatives, while the optimized point geometry ensures faster penetration and reduced bit walking compared to competitors.

FAQ

Q: What materials can this step drill handle?
A: Ideal for carbon steel, stainless steel, aluminum, brass, and copper up to 10mm thickness.
