Punta in metallo duro ø17.00 mm 8D
Punta con refrigerazione interna

The 8D ratio tackles deep-hole applications where chip evacuation and heat build-up are the primary failure modes. Internal coolant channels maintain cutting temperature and flush chips continuously, enabling consistent hole quality in steel, stainless, and ductile iron at depths where standard drills fail.

ø17.00mm 8D — recommended applications

  • Pressure vessel nozzle holes
  • Nuclear component drilling
  • Large-bore crankshaft oil passages
  • Ship engine block machining
Consiglio di lavorazione: At ø17.00mm, 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.
