* mandatory fields

Details

Application Areas:

Drilling of sheet, profiles and pipes up to 5 mm material thickness of structural steel, non-ferrous metal, stainless steel or plastics

Double-sided sheet deburring up to 1.5 mm material thickness

For core holes and through holes of cable tube fittings M12 x 1.5 / M16 x 1.5 / M20 x 1.5 / M25 x 1.5 / M32 x 1.5 (size 7 - 32.5)

Advantages:

  • No tool change necessary
    • Edge breaker zone enables drilling and reciprocal deburring without tool change
  • Long life
    • TiAlN (titanium nitride aluminum) coating ensures long life and high surface hardness and enables dry machining thanks to low friction
  • Fast drilling progress
    • 3-flat shank prevents slipping in the chuck and ensures optimum power transmission
    • Spiral flute guarantees a low-power, clean cut and fast chip removal (hardly any scratch marks on painted sheets)
  • Easy handling
    • Automatic chamfering and deburring due to the phase to the next larger diameter
    • No remeasuring due to readable drill diameter in the flute
    • Lasered speed recommendations for steel and stainless steel
    • Split tip without center punching and without drilling (also for curves)

Processing information

Do not use coolants and lubricants (it would destroy the coating)
Speed​​:
Steel 200-500 1/min
Stainless steel 100-250 1/min
