  • Four-Spiral-Flute Design: This M35 cobalt step drill bit set features four spiral flutes that enable chip removal and smoother cutting, reducing heat buildup during drilling in tough materials like stainless steel or aluminum, which significantly extends the tool’s lifespan and ensures cleaner holes.
  • Multi-Size Drilling Capability: Each step drill bit in this set drills multiple precise hole sizes—from 1/8 inch up to 7/8 inch—without needing to switch tools, making the M35 cobalt step drill bit perfect for fast, efficient work on metal, wood, and plastic projects.
  • Wide Application Versatility: The step drill bit set works effectively on stainless steel, sheet metal, aluminum, copper, wood, and plastic, serving DIYers, electricians, HVAC technicians, and metal fabricators who need clean, burr-free holes for panels, enclosures, or repairs.
  • Premium M35 Cobalt Construction: Made from high-speed M35 cobalt steel with 89HRC surface hardness, this step drill bit maintains sharpness far longer than standard HSS bits, offering superior wear resistance when cutting hard or abrasive materials repeatedly.
  • Universal 1/4 Inch Shank Compatibility: Featuring a standard 1/4 inch straight shank, the step drill bit fits most drill presses, hand drills, and impact drivers right out of the box; the kit includes three step drill bits and one standard drill bit for immediate use.
