The insert carries the IC806 manufacturer grade and is built from submicron carbide substrate for demanding cutting applications. It features an 80-degree trigon shape (W), a neutral 0-degree relief angle, and an M3M chip breaker designed to control chip flow under aggressive conditions. The insert measures 8.71 mm (0.343 inches) in length with a 1\/2-inch inscribed circle and a 1\/32-inch corner radius. It is double-ended and suitable for turning operations where heat resistance and edge toughness are critical priorities. Installation and use require a qualified machinist or CNC tooling specialist.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for machining superalloys and titanium, material group code S under ISO classification. The M3M chip breaker geometry provides positive rake cutting action, which reduces cutting forces and heat generation when working these difficult materials. It fits into standard WNMG-style toolholders with clamp and pin holding methods and is appropriate for both roughing passes and semi-finishing operations within its maximum depth of cut rating. The Isoturn series is suited for CNC lathe and turning center applications in aerospace, medical, and energy sector component machining where workpiece material hardness and work-hardening behavior demand a robust, wear-resistant insert grade.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC806 grade with TiAlN PVD SumoTec coating for high heat and wear resistance in superalloy and titanium cutting\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide substrate for improved toughness and edge retention\u003c\/li\u003e\n\u003cli\u003eM3M chip breaker with positive rake geometry to reduce cutting forces on difficult materials\u003c\/li\u003e\n\u003cli\u003eDouble-ended insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 5.00 mm (0.197 inches)\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard WNMG-style turning toolholders that accept clamp and pin insert holding.
