Turning troubleshooter · Insert wear

Inserts wear out fast

Even wear land on the flank grows quickly; size drifts and finish fades well before the expected life.

Likely causes

  • Cutting speed too high
  • A grade too tough, without the wear resistance
  • Hard spots or inclusions in the material
