It features a physical vapor deposition (PVD)-applied AlTiN (TiAlN) coating engineered for high wear resistance across a range of workpiece materials. The triangular insert shape provides three usable cutting edges, a 0.5 inch inscribed circle, a 1\/64 inch (0.0156 inch) corner radius, and an 11-degree relief angle with positive rake geometry. Maximum depth of cut reaches 0.2884 inches. The flat-top chip breaker design and honed cutting edge style suit finishing to medium-roughing turning operations. Licensed machinists and CNC turning specialists are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for turning, facing, and boring operations on steel (P), stainless steel (M), cast iron (K), aluminum and non-ferrous materials (N), superalloys and titanium (S), and hardened materials (H). The KCU10 grade delivers high to moderate wear resistance with adequate toughness for interrupted and continuous cuts on these material groups. It seats in a top-clamp (clamp-style) insert holder accepting TPG-style inserts. The KENDEX series is a multi-use line suited to general-purpose turning centers in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating applied by PVD process for elevated wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003eThree cutting edges per insert with neutral hand orientation for flexible setup\u003c\/li\u003e\n  \u003cli\u003e11-degree positive relief angle and positive rake geometry reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker with honed edge style for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.2884 inches suitable for finishing through medium roughing\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; compatible with clamp-style TPG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in clamp-style (top-clamp) toolholders that accept TPG-style triangular inserts per ANSI size code 431 and ISO size code 220404.
