Key Product Features
  • Premium HSS Engineering: Thermal-treated high-speed steel construction ensures exceptional durability, remaining sharp and rigid even under prolonged commercial use.
  • Titanium Protective Coat: Specially coated with ultra-thin titanium layer to minimize operational friction drag and dramatically reduce heat buildup.
  • Anti-Skid Hex Shank Layout: Features a deliberate 3-sided shank layout that locks securely into power tool chucks, ensuring zero slipping during high-torque applications.
  • Dual Flute Engineering: Dual specialized chip channels drive clean cutting action, automatically deburring holes as you transition seamlessly through sizing layers.
Broad Material Application Matrix:

Flawlessly handles drilling, sizing, and clean circular boring across a wide spectrum of project profiles:

  • Thin Sheet Iron, Structural Steel, & Brass plates
  • Aluminum sheeting & structural profiles
  • Rigid and flexible plastics, plexiglass, and acrylics
  • Hardwoods, plywoods, softwoods, and composite panels
Tool Compatibility & Best Practices:
  • Supported Tools: Seamlessly drops into standard Pistol Drills, Hand Drills, Charging/Cordless Drills, and industrial Bench Drill Presses.
  • Pro Tip for Extended Longevity: Injecting standard water or cutting-fluid cooling while cutting effectively doubles your bit's functional lifespan—highly advised during continuous thick metal drilling cycles.
Package Includes:
  • 1 x Premium HSS Titanium Step Drill Bit (Of your selected variant choice)
