Punta in metallo duro ø11.00 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.

ø11.00mm 8D — recommended applications

  • Engine block water jackets
  • Flange bolt-hole patterns
  • Pump housing bore features
  • Railway component deep holes
Consiglio di lavorazione: At ø11.00mm the internal coolant channel diameter increases significantly, improving chip flush at deeper ratios. Peck cycles can usually be eliminated.
