Punta in metallo duro ø8.00 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.

ø8.00mm 8D — recommended applications

  • Automotive fuel-system components
  • Hydraulic manifold ports
  • Gearbox housings
  • General precision engineering
Consiglio di lavorazione: ø8.00mm represents the sweet spot for coolant-thru drilling — feed rates of 0.15–0.25mm/rev are achievable with correct coolant pressure (20–40 bar).
