LOGIQ3CHAM - correct insert mounting

Highlights
ISCAR is expanding the application range of the successful LOGIQ3CHAM drilling line by adding an 8 L/D ratio holder.



The new holder with an 8 L/D ratio has a unique flute design that utilizes the productivity advantages of the LOGIQ3CHAM line. The flute length a has minimal influence on the tool’s structural strength.

  • The recommended cutting conditions are the same as those recommended for the existing LOGIQ3CHAM line.
  • The new 8 L/D holder is appropriate for any LOGIQ3CHAM drilling head geometries with the same pocket size.
