ø20.00 mm 5D Solid Carbide DrillNo Internal Coolant · External Flood Compatible

The 5D ratio extends capability beyond standard depth without requiring the higher tooling cost of through-coolant drills. With external flood coolant and correct chip-breaking cycle, the 5D solid carbide drill achieves consistent hole quality in structural steel, cast iron, and aluminium alloys. A cost-effective choice when machine spindle does not support internal coolant.

ø20.00mm 5D — 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.
