Punta in metallo duro ø18.00 mm 3D
Punta con refrigerazione interna

The 3D depth ratio is the workhorse of through-hole and short-blind-hole drilling. With the shortest flute-to-diameter ratio in the range, the 3D offers maximum rigidity and excellent straightness in steels, cast iron, and aluminium alloys. Ideal for high-feed automotive and general engineering applications where cycle time is critical.

ø18.00mm 3D — recommended applications

  • Pressure vessel nozzle holes
  • Nuclear component drilling
  • Large-bore crankshaft oil passages
  • Ship engine block machining
Consiglio di lavorazione: At ø18.00mm, tool deflection becomes a factor in deep ratios. Use a 4-facet point geometry and reduce feed by 15–20% for the first 2D of entry until the drill self-guides.
