Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and coolant delivery efficiency.

Operating Guidelines

  • Tool Overhang: Minimize overhang to ≤ 4×D for optimal rigidity and hole accuracy.
  • Peck Drilling: For holes deeper than 3×D, employ a peck cycle with 1×D–1.5×D peck depth and full retraction every 3–4 pecks.
  • Coolant Pressure: Maintain minimum 20 bar (290 psi) for through-tool coolant; 70+ bar recommended for stainless steel and superalloys.
  • Entry Surface: Ensure flat, perpendicular entry surface. For inclined or curved surfaces, use a center drill or spot drill first.
  • Tool Change Protocol: Monitor flank wear (VBmax = 0.3 mm). Replace immediately when chipping, built-up edge, or discoloration is observed.
  • Speed/Feed Ramping: Reduce spindle speed by 20% and feed by 10% during tool entry and exit to minimize burr formation.
