???? Operating Guidelines

  • Tool Setup: Ensure insert seat is clean and free of debris before mounting. Use correct torque (2.5–3.5 Nm for clamping screw).
  • Coolant: High-pressure coolant (70+ bar) recommended for chip evacuation and extended tool life. Use water-soluble coolant for steel and emulsion for stainless.
  • Run-In: Reduce cutting speed by 20% for the first 5 minutes of operation to stabilize the cutting edge.
  • Inspection: Check for flank wear (VB ≤ 0.3 mm) and crater wear (KT ≤ 0.1 mm) at regular intervals. Replace insert before catastrophic failure.
  • Storage: Store in original packaging at 15–25°C, humidity <60%. Avoid direct sunlight and corrosive atmospheres.

???? Toolholder Compatibility
