Built from solid carbide and finished with a multilayer MTCVD TiCN and Al2O3 coating, it balances moderate wear resistance with toughness to handle both roughing and medium machining passes. The insert features an 80-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, and a 1\/64-inch corner radius. With four usable cutting edges and a neutral hand orientation, it delivers consistent performance across a variety of CNC lathe setups. Licensed machinists and tooling technicians working in production or job-shop environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary use on steel (P-grade workpieces) and stainless steel (M-grade workpieces), with secondary suitability for superalloys and titanium (S-grade). The MP chip breaker geometry supports roughing and medium machining applications, making it a practical choice for high-material-removal roughing passes as well as transitional medium-cut operations. The KENLOC series designation indicates compatibility with KENLOC-style toolholders that accept CNMG-style inserts held by clamp or pin. Maximum depth of cut is 1.25 mm (0.0492 inches) under recommended conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCM15 grade with multilayer MTCVD TiCN and Al2O3 CVD coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake and negative side clearance for strong cutting edge\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker geometry suited for roughing and medium machining passes\u003c\/li\u003e\n  \u003cli\u003eFour indexable cutting edges with chamfered and honed cutting edge style\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for use in standard right- or left-hand turning setups\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI CNMG431 and ISO CNMG120404 standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG-style inserts secured by clamp or pin.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and evenly in the toolholder pocket before tightening the clamp or pin to avoid micro-fracture at the cutting edge. Verify proper seating and torque the clamping screw per the toolholder manufacturer specifications 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: CNMG431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM15\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: TiCN and Al2O3 (Multilayer CVD, MTCVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 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 (5.16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MP (Roughing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 6 degrees (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\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: C2, C3\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: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (sold in multiples of 5)\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: 3755684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740690678066,"sku":"3755684","price":182.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63ca32f144b6e2592a1e58b4be243474.jpg?v=1788826746","url":"https:\/\/voomisupply.com\/products\/kennametal-3755684-turning-insert-cnmg431mp-kcm15-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
