It features a 60-degree triangle shape with a neutral hand orientation and a 0 degree relief angle (clearance code N). The insert carries a multi-layer CVD coating of TiC, TiCN, and TiN under manufacturer grade HC335, which improves wear resistance and heat tolerance during interrupted and continuous cuts. The inscribed circle measures 3\/8 inch (0.375 inches), insert length is 0.433 inches, and thickness is 1\/8 inch (0.125 inches). The corner radius is 1\/64 inch (0.0156 inches). This insert is held in place by a clamp-style toolholder and is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003cp\u003eThe 1001351 is suited for turning operations on ferrous workpiece materials, corresponding to ISO material groups P (carbon and alloy steels) and M (stainless steels). Material grades C5 and C6 indicate suitability for finishing to semi-finishing passes. It is appropriate for both residential machine shops and commercial production environments where consistent surface finish and tool life on steel and stainless applications are required. The neutral insert hand makes it compatible with a wide range of standard TNG-style toolholders without requiring a left- or right-hand designation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating under grade HC335\u003c\/li\u003e\n  \u003cli\u003e60-degree triangle insert shape (shape code T) with 0 degree relief angle and tolerance code G\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 1\/64 inch (0.0156 inches) for finishing and semi-finishing applications\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 3\/8 inch supports stable engagement in standard TNG clamp-style toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits a broad range of standard TNG turning toolholders\u003c\/li\u003e\n  \u003cli\u003eNo chip breaker geometry (chip breaker code N) for consistent performance on open-face cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in clamp-style TNG turning toolholders accepting a 3\/8 inch inscribed circle triangle insert.
