SMG
(G class)
  • For medium cutting.
  • 3D moulded chipbreaker provides good chip control.
  • G class insert gives sharp cutting action, allowing high precision machining.
 CCGH/CCGT Type － －
FV
(M class)
  • Sharp cutting edge and low resistance design achieves excellent cutting performance.
  • Suitable for low depths of cut and low feed rates.
 － CCMH/CCMT/CPMH/CPMT Type DCMT Type
SV
(M class)
  • For light cutting.
  • A peninsular dot ensures chip control at depths of cut under 1mm.
 － CCMH/CCMT/CPMH/CPMT Type DCMT Type
MV
(M class)
  • A positive insert and the large rake angle achieve sharp cutting edge performance.
  • The double breakers and round-shaped dots in the rake face achieve a wide range of chip discharge.
 － CCMH/CCMT/CPMH/CPMT Type DCMT Type
Standard
(M class)
  • For medium cutting.
  • Balance of edge strength and sharpness due to a combination of a flat land and large rake angle.
 － CCMH/CCMT/CPMH/CPMT Type DCMT Type
FJ
  • The curved edge allows smooth chip discharge.
  • The large rake angle highly suitable for finishing difficult-to-cut materials.
 CCGH/CCGT Type － －
MJ
  • The curved edge allows smooth chip discharge.
  • Large rake angle highly suitable for finish-light cutting difficult-to-cut materials.
