This insert features a 55-degree diamond (rhombic) shape with a negative rake angle of 12 degrees, a neutral hand orientation, and a honed cutting edge style. It carries four usable cutting edges and is engineered for finishing operations on steel, stainless steel, superalloys, and titanium. Licensed HVAC and machining professionals handling high-wear applications in P, M, K, N, S, and H workpiece material categories will recognize the KCU10 grade as a high wear-resistance to moderate toughness performer across those material groups.\u003c\/p\u003e\u003cp\u003eThis insert is suited for light finishing passes in CNC turning centers and manual lathes. Applicable operations include turning, facing, boring, back turning, and back boring. The FS chip breaker geometry is optimized for finishing cuts at shallow depths of cut, making it a reliable choice for close-tolerance work on steel and stainless steel components in both production and repair-shop environments. The insert fits KENLOC-series toolholders that accept DNGG-style inserts secured by a clamp and pin holding method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating for high wear resistance across steel, stainless steel, and cast iron applications\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape provides a sharp, low-force cutting geometry for finishing operations\u003c\/li\u003e\n\u003cli\u003eFS chip breaker designed for finishing cuts with a maximum depth of cut of 0.080 inches (2.03 mm)\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert, neutral hand orientation for flexible toolholder fitment\u003c\/li\u003e\n\u003cli\u003eKCU10 grade rated for Steel (P), Stainless Steel (M), Cast Iron (K), Aluminum, Superalloys, and Titanium workpiece materials\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping during light finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting DNGG-style inserts with a clamp and pin holding method.

Ensure the toolholder pocket and locating pin are free of chips and debris before seating the insert. Torque the clamping screw according to the toolholder manufacturer specifications — do not substitute generic torque values. Inspect the cutting edge for micro-chipping before each use; a damaged edge on a finishing insert can compromise part surface finish and dimensional tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: DNGG150404FS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNGG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55-Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FS (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 12 degrees (Negative)\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.2208 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\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: 0.080 inches (2.03 mm)\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\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium, Cast Iron, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5109296\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749639094578,"sku":"5109296","price":305.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cab67dbe981004697f5842fdfc25d8f_43066fb0-a7b1-4201-bed5-81105d734b84.jpg?v=1788908659","url":"https:\/\/voomisupply.com\/products\/kennametal-5109296-dngg431fs-kcu10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
