Recommended Cutting Conditions

Parameters below are starting recommendations for external coolant setups. Adjust based on machine rigidity, workpiece fixturing, and coolant pressure.

MaterialCutting Speed Vc (m/min)Feed fn (mm/rev)Coolant
Carbon Steel (P1)80 – 1200.10 – 0.18Emulsion / MQL
Alloy Steel (P2–P3)60 – 900.08 – 0.15Emulsion 8–10%
Stainless Steel (M1)40 – 650.06 – 0.12High-pressure coolant
Cast Iron (K1)70 – 1000.10 – 0.20Compressed air / MQL
Titanium (S1)25 – 400.05 – 0.10High-volume emulsion

Operating Guidelines

  • Runout Tolerance: Maintain spindle runout < 0.01 mm (0.0004") for optimal tool life and hole quality.
  • Coolant Pressure: For 8XD drilling, minimum 70 bar (1,000 psi) through-spindle coolant is strongly recommended to ensure chip evacuation.
  • Peck Cycle: Use a variable peck depth (Q) of 1.5–2.0×D for the first peck, reducing to 1.0×D for subsequent pecks.
  • Entry Angle: Ensure perpendicular entry or use a spot drill to prevent chipping of the cutting corners.
  • Re-sharpening: Not recommended; this solid carbide drill is designed as a disposable tool for consistent performance.
  • Storage: Keep in original packaging until use. Avoid contact between cutting edges and hard surfaces.
