It features a 55-degree diamond insert shape, a neutral hand orientation, and a TiCN plus NbC coating classification listed as uncoated process with a TN60 manufacturer grade cermet substrate. The insert carries a 0.0156-inch corner radius, an inscribed circle of 0.375 inches, and an insert length of 0.914 inches. The HQ chip breaker geometry and honed cutting edge style make this insert well-suited to finishing and semi-finishing passes. Licensed machinists and CNC operators handling production turning work will find it appropriate for demanding dimensional tolerances on steel and stainless steel workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily applied to external turning, boring, and copying operations. Primary workpiece material is steel, with stainless steel listed as the secondary workpiece material. It carries material grade designations of P01, P10, and P20, indicating suitability across a range from precision finishing to light roughing cuts on ferrous materials. The ISO insert code is DNMG110404HQ and the industry standard number is DNMG331HQTN60. The insert conforms to both ANSI and ISO standards and is classified under UNSPSC code 23242105. This is a multi-use insert compatible with boring, copying, and external turning applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCermet substrate with TN60 grade for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (shape code D) with negative rake angle of -15 degrees\u003c\/li\u003e\n  \u003cli\u003eHQ chip breaker with honed cutting edge for controlled chip formation in finishing cuts\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3047 inches suitable for semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code DNMG110404HQ\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting DNMG-style inserts with clamp or pin holding methods.
