8D · Solid Carbide Drill · ø4.00mm

Punta integrale ø4.00 mm 8DSenza refrigerazione interna · compatibile con refrigerante esterno

The 8D solid carbide drill without internal coolant is suited to machines with external high-pressure coolant delivery or where through-coolant tooling is not available. Peck drilling cycles with proper chip-break intervals are essential at this depth. Consistent substrate quality and Balzers PVD coating maintain cutting edge integrity across the full flute length.

Dove questo utensile eccelle

ø4.00mm 8D — recommended applications

  • ▸ PCB sub-assembly fixtures
  • ▸ Small instrument housings
  • ▸ Jig & fixture components
  • ▸ Prototype precision parts
Consiglio di lavorazione: At ø4.00mm, use compressed air rather than flood coolant to prevent re-cutting of fine chips. Feed rate 0.04–0.08 mm/rev; spindle speed up to 8,000 RPM depending on material.
Coolant Advice: Compressed air or light oil mist recommended. External flood coolant acceptable at lower feed rates.
