This is a factory-new, sealed box of 10 Iscar GFN 4B IC308 carbide grooving inserts, manufactured in Israel. The GFN designation identifies these as single-ended grooving inserts in Iscar's GIGA-N system, with a 4mm grooving width and 'B' chipbreaker geometry optimized for medium-feed grooving; the uncoated IC308 grade is a fine-grain cemented carbide without PVD or CVD coating, suited for grooving stainless steel and other ISO M materials. Per the package label, recommended cutting parameters are Vc = 140–180 m/min (460–590 sfm) and feed fz = 0.10–0.30 mm/t (0.004–0.012 ipr). These inserts are compatible with Iscar GIGA-N toolholders designed for the GFN insert family, including holders in the GHDR and GHBL series that accept 4mm-width single-ended grooving inserts.
