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
