Operating Guidelines

  • Ensure toolholder pocket is clean and free of chips before insert installation
  • Torque clamping screw to manufacturer specification (typically 2.5–4.5 N·m)
  • Use water-miscible coolant (5–8% concentration) or neat cutting oil for best tool life
  • Reduce cutting speed by 15–20% for interrupted cuts or scale/rusty workpieces
  • Increase feed by 10–15% for chipbreaker activation in shallow cuts
  • Monitor flank wear (VB) and replace insert when VB exceeds 0.3 mm
  • Store inserts in original packaging away from moisture and direct sunlight
