Recommended Cutting Conditions

Parameters are indicative; optimize based on machine rigidity and setup:

Workpiece MaterialCutting Speed Vc (m/min)Feed fn (mm/rev)Depth ap (mm)
Carbon Steel (≤HB 200)132-1520.16-0.214.5
Alloy Steel (HB 200-280)112-1320.16-0.193.6
Stainless Steel92-1120.14-0.162.7
Cast Iron (HB 180-260)122-1420.18-0.245.3

Note: Reduce cutting speed by 15-20% for interrupted cuts or less rigid setups. Use coolant for stainless steel and heat-resistant alloys.

Operating Guidelines

  • Ensure toolholder runout is below 0.01 mm for optimal hole accuracy
  • Use through-coolant toolholders for deep-hole applications (>2×D)
  • Verify insert seating and clamping force before each operation
  • Monitor flank wear; replace insert when VBmax exceeds 0.3 mm
  • Apply appropriate entry strategy (pre-drill or ramp entry for solid material)
  • Maintain consistent feed rate to avoid chip packing and insert fracture
