• WFN-WFX and OHN-OHX are the blade's extension range • Grooving depth (CDX) varies in conformance with blade's overhang (OHN-OHX) and depends on the bore
diameter(D). For grooving capacity, see graph
• When using TIP inserts, the toolholder seat needs to be modified • For user guide, see pages 419-428, 432-436
