Conforming to ANSI insert code TNMP321 and ISO insert code TNMP160304, this insert features a 60-degree triangular shape with a negative side clearance and a 0 degree relief angle. The inscribed circle measures 3\/8 inches and the corner radius is 1\/64 inches, making it well-suited for moderate finishing and light roughing passes. Manufacturer grade TCN55 indicates a coated carbide grade appropriate for steel and stainless steel workpiece materials. Installation is performed by machinists and toolroom technicians as part of standard insert changeout procedures.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in turning operations on ferrous workpiece materials, including carbon steel and stainless steel, corresponding to primary workpiece material codes P and M. The TNMP insert style uses a combination clamp and pin holding method, which provides rigid seating in compatible toolholders. Typical applications include OD turning, facing, and light contouring on both manual and CNC lathes in job shop and production environments. Each package contains one insert. The minimum order quantity is 10 inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in manufacturer grade TCN55 for wear resistance on steel and stainless workpieces\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape provides three usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle with 1\/64 inch corner radius for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eNegative side clearance with clamp and pin holding method for secure toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eANSI insert code TNMP321 and ISO insert code TNMP160304 for cross-reference compatibility\u003c\/li\u003e\n  \u003cli\u003eChip breaker style P to support controlled chip formation during steel turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style turning insert for toolholders accepting TNMP321 ANSI-standard inserts with clamp and pin holding configurations.
