When the air blow is less effective at discharging chips, we recommend wet cutting. Note 2) When wet cutting, tool life may become shorter than dry cutting. When carrying out wet cutting for the applications recommended with dry cutting, reduce the cutting speed by 25%. Note 3) When large vibration occurs, reduce the cutting conditions. Note 4) For interrupted cutting, reduce the cutting speed and feed rate by 20%. M176
