Insert Grade Finds Use with Groove Milling Tools


GC1130 insert grade delivers high metal removal rates and secure performance levels in both wet and dry machining operations.


Machine shops can now use grade GC1130 inserts with CoroMill QD for deep and narrow grooving in both external and internal roughing and finishing operations. For additional groove milling requirements, GC1130 inserts can also be applied to CoroMill 331, a multi-purpose side and face milling cutter.


GC1130 overcomes such issues as flaking, abrupt chipping, and thermal cracks that are commonly encountered when milling materials in the ISO P application area,




Grade GC1130 inserts offer:

  • high edge-line security
  • reduced flaking
  • longer insert life
  • stable production
