It features a Physical Vapor Deposition (PVD) TiN coating applied to a 55-degree diamond (rhombic) carbide substrate, delivering high wear resistance across a range from moderate to demanding cuts. The insert is neutral-hand, uses an LF chip breaker geometry rated for finishing and light machining operations, and holds four usable cutting edges. At 15.5 mm in length with a 0.5-inch inscribed circle and a 1\/64-inch corner radius, it fits KENLOC-style toolholders that accept clamp-and-pin holding. Licensed machinists and CNC turning specialists install this insert in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations on steel, stainless steel, and cast iron, with secondary capability on superalloys and titanium. The KC730 grade is engineered for ISO material groups P (steel), M (stainless steel), and K (cast iron), providing a balance of wear resistance and toughness that covers both finish passes and light stock-removal work. It conforms to ANSI and ISO standards and carries material grade designations C2, C3, and C4, making it appropriate across a broad range of production turning setups where surface finish and edge life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 grade PVD TiN coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DNGG) with LF chip breaker for finishing and light machining\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert, neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style with negative rake angle (10 degrees) and negative side clearance\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 0.0492 inches (1.25 mm) for controlled finishing passes\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods in KENLOC-series toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ANSI code DNGG431, ISO code DNGG150404\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept DNGG-style inserts with clamp and pin holding.

Confirm the toolholder clamp and pin are free of chips and seating surfaces are clean before securing the insert to maintain proper geometry and runout. Consult the toolholder manufacturer specifications for correct clamping torque and insert seating procedure. Verify depth-of-cut and feed parameters are within the LF chip breaker range before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNGG431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNGG150404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF - Finishing \/ Light Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.5 mm (1.2208 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0265 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1160850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728540762418,"sku":"1160850","price":312.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/868ab5fe1319a2816afb93c98baa2ddf.jpg?v=1788692996","url":"https:\/\/voomisupply.com\/products\/kennametal-1160850-turning-insert-dngg431lf-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
