3 Toolholder lineup to meet various applications Fine and extra fine pitch types available. Fine pitch (Example: ø125, 12 inserts) • Recommended for unstable setups • General purpose for wide application ranges Extra fine pitch (Example: ø125, 18 inserts) • Recommended for rigid setups • Finer pitch for higher efficiency 4 Chipbreaker lineup for wide range of applications General purpose: GM chipbreaker Heavy duty: GH chipbreaker Finishing: GL chipbreaker (Ground) Wiper edge: W chipbreaker (Ground) 5 Long tool life and stable machining CA420M features advanced CVD coated CRIOS technology. Longer tool life Controlled α-Al2O3 crystal growth for improving wear resistance and fracture resistance. Prevents lm peeling 40 % improved lm adhesion by optimized interface. Increased edge strength Higher lm strength and fracture resistance with high aspect ratio TiCN.
