ø9.00 mm 8D Solid Carbide DrillNo Internal Coolant · External Flood Compatible

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.

ø9.00mm 8D — recommended applications

  • Engine block features
  • Gearbox component drilling
  • Hydraulic manifold ports
  • Fixture plate tooling
Machining Tip: At ø9.00mm, chip volume is significant. Peck depth should not exceed 1.5×D for 5D+ holes without internal coolant. Increase coolant pressure to ≥ 20 bar for improved chip flush.
Coolant Advice: High-pressure external coolant (≥ 20 bar) strongly recommended. Regular peck cycles mandatory at 5D+.
