CW = Cutting Width CDX = Max. Groove Depth CUTDIA = Max. Cut Off Diameter
*1 The maximum groove depth (CDX) varies according to the insert used. Please refer to the maximum groove depth (CDX) of inserts on pages F011 to F015.
**2 The maximum cut off diameter (CUTDIA) varies according to the insert used. The cut off diameter is double the maximum groove depth (CDX ) of inserts on pages F011 to F015.
*3 Dimensions shown are when the gauge insert is used. If other insert geometries are used then LF, LH and LH 2 values may vary.: USA Stock : Stocked in Japan
F0404 The maximum groove depth (CDX) is limited by the workpiece diameter. For details, please refer to page F208.F238as
