It features a 55-degree diamond shape, a 0.5-inch inscribed circle, a 0.0315-inch corner radius, and a flat-top chipbreaker geometry. The insert carries manufacturer grade CBN010, is uncoated (bright finish), and uses a negative rake, neutral hand orientation. With two cutting edges and a chamfered and honed cutting edge style, it delivers consistent performance in demanding interrupted and continuous cut applications on hard materials. Licensed machinists and CNC operators install this insert in production turning operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for primary use on hard materials (ISO material code H) and secondary use on super-alloys and titanium (ISO material code S). Typical applications include back turning, boring, facing, and standard OD turning. It is well suited for finishing and semi-finishing passes where tight tolerances and surface finish quality are critical. The flat-top chip geometry and chamfered-honed edge support stable cutting in hardened steels and similar workpiece materials at elevated surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material (manufacturer grade CBN010) rated for hard materials and super-alloys\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with 0.0315-inch corner radius for precise contouring\u003c\/li\u003e\n  \u003cli\u003eFlat top chipbreaker series with chamfered and honed cutting edge for edge stability\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with back turning, boring, facing, and turning operations\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; multi-tipped construction for extended tool life\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code DNGA150408S-01020-L1-B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNGA-style toolholders accepting a 432 insert size with clamp, pin, or lever-lock holding methods.
