It features an 80-degree diamond (rhombic) shape with a neutral hand orientation, a 0.5-inch inscribed circle, and a 0.03125-inch corner radius. The insert carries Kennametal grade K68, engineered for high wear-resistance across stainless steel, cast iron, aluminum, and other non-ferrous materials. With 4 cutting edges and a negative rake and side clearance design, it delivers consistent performance in medium machining conditions. Licensed machinists and CNC operators install this insert in turning, facing, and boring applications where dimensional repeatability and edge life are priorities.\u003c\/p\u003e\u003cp\u003eThis insert is suited for CNC turning centers and manual lathes performing turning, facing, and boring operations. Its K68 grade characteristics make it effective on stainless steel (M), cast iron (K), aluminum, and non-ferrous materials (N), as well as superalloys and titanium (S). The CNMS432 geometry is a common fit in KENLOC-style toolholders that accept clamp and pin insert-holding methods. The medium chip breaker profile supports stable cuts at moderate feeds and depths, with a maximum depth of cut of 0.0492 inches (1.25 mm). It conforms to both ANSI and ISO standards under codes CNMS432 and CNMS120408, respectively.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake and negative side clearance for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003eSolid carbide K68 grade with bright\/uncoated finish for high wear-resistance on stainless steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with both left- and right-hand tooling setups\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for consistent edge integrity on medium machining applications\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI (CNMS432) and ISO (CNMS120408) standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept CNMS432 geometry inserts secured by clamp and pin holding methods, conforming to ANSI and ISO insert standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Use the appropriate torque wrench and clamp hardware specified for KENLOC-style holders to avoid insert movement or chipping. Inspect the insert pocket for debris or damage before each insert change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMS432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMS120408\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\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03125 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5077 inches (12.90 mm)\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\u003eInsert Width\u003c\/strong\u003e: 0.5 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: 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\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 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\u003eChip Breaker\u003c\/strong\u003e: Common (Medium Machining)\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\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys and Titanium, Stainless Steel, 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: 0.019 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: 1161155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732686962994,"sku":"1161155","price":144.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93af924fe41b24e9cad6be40d48ec7f3.jpg?v=1788745730","url":"https:\/\/voomisupply.com\/products\/kennametal-1161155-cnms432-k68-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
