ø20.00 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.

Where This Tool Excels

ø20.00mm 8D — recommended applications

  • ▸ Large-scale structural drilling
  • ▸ Mining and energy equipment
  • ▸ Heavy vehicle chassis features
  • ▸ Offshore component machining
Machining Tip: At ø20.00mm, the 3D and 5D ratios are well-managed with external flood coolant. For 8D depths at this diameter, strongly consider the coolant-thru variant — chip jam risk is high without internal flush at large diameters.
Coolant Advice: Flood coolant mandatory at all depths. Coolant-thru variant strongly recommended for 8D holes at this diameter.
