Identified by ISO code TNMG 543-GN, this insert carries the IC8250 manufacturer grade and features a CVD-applied tri-layer coating of TiCN, Al2O3, and TiN. The coating sequence delivers thermal resistance and wear protection suited to continuous and interrupted cuts. The GN chip breaker geometry supports controlled chip formation across a range of feeds and depths. With an inscribed circle of 0.625 inches and an insert length of 1.083 inches, this is a mid-size triangular insert suitable for production turning on CNC lathes and manual turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is classified under the Isoturn series and carries ISO 13399 compliance. It is intended for single-end use and is compatible with clamp and pin-style toolholders that accept TNMG-geometry inserts. Primary workpiece material codes are P (steel) and M (stainless steel), making it a practical choice for job shops and production facilities running mild steel, alloy steel, and austenitic stainless grades. Maximum depth of cut is 6.00 mm (0.236 inches). It is installed by machinists and CNC operators in metalworking environments. Minimum order quantity is 10 inserts; package quantity is 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC8250 grade with CVD TiCN\/Al2O3\/TiN coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eGN chip breaker geometry for controlled chip evacuation across varied feed rates\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape (TNMG style) with 0-degree relief angle and N clearance code\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.047 inches (3\/64 inches) for general-purpose finishing and semi-finishing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 6.00 mm (0.236 inches)\u003c\/li\u003e\n\u003cli\u003eISO 13399 compliant; compatible with clamp and pin toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders accepting clamp and pin holding methods.
