It features a 60-degree triangular shape with a negative side clearance (N clearance code) and a flat-top chip breaker geometry. The inscribed circle measures 3\/8 inches (0.375 inches), insert thickness is 1\/8 inches (0.125 inches), and the corner radius is 1\/32 inches (0.031 inches). Manufactured to grade TCN55 with an ISO material grade of C5, this insert is suited for turning operations on steel and stainless steel workpiece materials. It is held in the toolholder via clamp and pin method.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in CNC and manual turning centers where a negative-rake TNMA-style seat is required. The TCN55 grade and C5 material classification make it appropriate for general-purpose turning of ferrous materials including carbon steels and stainless steels, corresponding to ISO material codes P and M. Machinists and tooling technicians select this geometry for interrupted and continuous cuts where the triangular insert shape provides up to six usable cutting edges across both faces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, manufacturer grade TCN55, ISO material grade C5\u003c\/li\u003e\n\u003cli\u003eANSI insert code TNMA322 \/ ISO insert code TNMA160308\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape with flat-top chip breaker\u003c\/li\u003e\n\u003cli\u003eInscribed circle: 3\/8 inches (0.375 inches); corner radius: 1\/32 inches (0.031 inches)\u003c\/li\u003e\n\u003cli\u003eNegative side clearance (N), tolerance code M\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in TNMA toolholders\u003c\/li\u003e\n\u003cli\u003eHole diameter: 0.150 inches for locating pin engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMA-style negative-rake turning toolholders that accept a 322 ANSI size code insert with clamp and pin retention.
