90 Notes for use of HJ-type inserts

HJ-type inserts can be used for high feed machining.

When using the insert, care should be taken with the following:

Others a

  • The maximum depth of cut is p = 2 mm. Select feeds within the above value.
  • Do not use the HJ-type inserts with other types (such as MJ- and MS-types) in the same body.
  • The outer shape of the HJ-type insert is different from those of other types (such as MJ- and MS-types), but the insert can be held in the same insert pocket.
