AlTiN-coated straight-flute step drill bit manufactured from HSS-Co5 M35 cobalt high-speed steel for progressive drilling and hole enlargement in sheet materials. Available in three drilling ranges with diameter-specific 3-flat shanks for compatible handheld drills and stationary drilling machines.

Key Features

  • HSS-Co5 M35 cobalt high-speed-steel substrate provides high hardness, heat resistance and wear resistance
  • AlTiN coating improves surface hardness and wear resistance during demanding metal drilling
  • Straight-flute step geometry supports controlled hole enlargement, deburring and chamfering
  • Clearly marked cutting diameters allow the required hole size to be selected during drilling
  • 3-flat shank provides secure chuck engagement and helps reduce slipping under load

Tool Compatibility

  • The 4–12 mm variant requires a three-jaw chuck capable of accepting a 6 mm 3-flat shank
  • The 4–20 mm variant requires a three-jaw chuck capable of accepting an 8 mm 3-flat shank
  • The 4–32 mm variant requires a three-jaw chuck capable of accepting a 10 mm 3-flat shank
  • Compatible with suitable high-power handheld electric drills, pillar drills, drill presses and magnetic drilling machines
  • A stationary drilling machine is recommended for thicker material and larger hole diameters

Operating Guidance

  • For approximately 1 mm stainless steel, the supplier recommends a handheld electric drill rated above 750 W
  • For material approximately 2–5 mm thick, use a stable pillar drill or drilling machine and keep spindle speed below approximately 500 r/min
  • Apply suitable coolant or cutting fluid continuously when drilling stainless steel
  • Reduce spindle speed as the active drilling diameter or workpiece thickness increases
