Per the ISO designation, the insert is 15.875 mm (5\/8 in) inscribed circle, 4.76 mm thick, with a 0.8 mm nose radius, a 7° clearance angle (N), medium (M) chipbreaker geometry (EGZ — Sumitomo's EGZ chipbreaker designed for medium interrupted and continuous cuts), and a cylindrical through-hole (G hole) for screw clamping. The dark PVD\/CVD black topcoat with gold TiN inner layer is clearly visible in the photos, consistent with AC405K's published appearance. Compatible toolholders follow the DDJN\/DDNN\/PDDN turning holder families accepting 55° diamond inserts with screw-lock (hole-type) clamping; the box label confirms a 10-piece factory pack made in Japan.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
