Application
For producing drill holes with a 180° hole base in one operation

Execution
Heavy-duty solid carbide drill with 180° precision grinding and drill heels

Advantage
  • Drilling and sinking in a single work step at high cutting speed
  • Innovative geometry ensures good chip removal

Notes
The maximum permissible inclination of the drilling surface is 45°
inclination up to 15° correction factor = 0.50
inclination up to 30° correction factor = 0.40
inclination up to 45° correction factor = 0.25
For spot drilling, multiply feed f [mm/r] by correction factor Cf
  • Spot drill with reduced feed until the tool cuts to 0.25xD over the total ø

  • For angled spot drilling: Retract at double feed rate f [mm/r]

  • After spot drilling at reduced feed rate (correction factor), drilling continues at feed rate f [mm/r] according to recommended cutting data without correction factors
