ø7.00 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.

ø7.00mm 5D — recommended applications

  • General engineering components
  • Automotive bracket features
  • CNC machining centre jobs
  • Pump and valve bodies
Machining Tip: ø7.00mm is the most common range for general engineering. Use external flood coolant at 10–15 L/min. Without internal channels, maintain peck depth ≤ 2×D at 5D+ to prevent chip packing.
Coolant Advice: External flood coolant at 10–15 L/min. Peck drilling recommended for depths beyond 3×D.
