It features a multilayer PVD coating of TiN, TiCN, and TiN, which provides thermal stability and extended edge life in finishing operations. The insert carries a 55-degree diamond (rhombic) shape with a neutral hand orientation, a 0.5-inch inscribed circle, and a 1\/64-inch corner radius. The FW chip breaker geometry is engineered for wiper finishing, producing tight surface finishes at elevated feed rates. This insert is installed and indexed by machinists and CNC lathe operators in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations on steel (P), stainless steel (M), and cast iron (K) workpiece materials. The KT315 grade delivers high wear resistance across all three material classifications, making it appropriate for both general-purpose and precision finishing passes in light-to-moderate cut depths. Maximum depth of cut is 0.0492 inches (1.25 mm). It fits toolholders within the KENLOC series and is compatible with clamp and pin holding methods.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer PVD coating (TiN \/ TiCN \/ TiN) for high wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eFW wiper chip breaker geometry optimized for finishing passes at increased feed rates\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with negative rake and negative side clearance (DNMG style)\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for use in a wide range of KENLOC-style toolholders\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces microchipping at the edge on interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC series toolholders that accept DNMG431 inserts with clamp or pin holding methods.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can crack the insert body. Inspect the insert pocket and locating surfaces for chips or debris before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150404\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\u003eManufacturer Grade\u003c\/strong\u003e: KT315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN \/ TiCN \/ TiN Multilayer PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FW (Wiper Finishing)\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: 15.50 mm (0.5-inch width class)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\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: 0.0492 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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 0.0115 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: 1783137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730744181042,"sku":"1783137","price":227.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34cc6a1c354ad4e12e3373dbc85721a1.jpg?v=1788722107","url":"https:\/\/voomisupply.com\/products\/kennametal-1783137-dnmg431fw-kt315-cermet-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
