Summary: Methods to improve chip handling

Reduce the blade rake angle (*side effect: increased cutting resistance)

Reduce the width of the chip flute (*side effect: increased cutting resistance)

Reduce cutting speed (*side effect: working hours increase)

Increase feed (*side effects: increased cutting resistance, risk of chipping, poor finish)
