It carries a CVD-applied multilayer coating of TiC, TiCN, and TiN, which delivers a balance of moderate wear resistance and toughness across a range of workpiece materials. The insert features a triangular shape with a 60-degree included angle, a 0.5-inch inscribed circle, and a 0.0312-inch corner radius. Neutral hand orientation makes it suitable for both right-hand and left-hand toolholders configured for TNMG-style inserts. Licensed HVAC techs and machinists in production and job-shop environments rely on this insert for consistent chip control using the K chip breaker geometry.\u003c\/p\u003e\u003cp\u003eThe 1160285 is suited for turning steel, stainless steel, cast iron, and select superalloys in moderate to high material removal applications. The KC850 grade is characterized as offering moderate wear resistance combined with toughness, making it a versatile choice when surface finish and tool life must be balanced against interrupted cuts or variable stock conditions. It is appropriate for residential and commercial machine shops, production turning cells, and maintenance repair operations where KENLOC-series tooling systems are already in use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiC, TiCN, and TiN for wear resistance and toughness across steel, stainless, and cast iron\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape with 60-degree included angle and negative side clearance for stability under load\u003c\/li\u003e\n\u003cli\u003e0.5-inch inscribed circle and 0.8661-inch insert length for rigid seating in KENLOC-compatible holders\u003c\/li\u003e\n\u003cli\u003eK chip breaker geometry designed to control chips during moderate-depth turning passes\u003c\/li\u003e\n\u003cli\u003eCompatible holding methods include top clamp and center pin for secure insert retention\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.0492 inches (1.25 mm) as rated by manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for KENLOC-series toolholders accepting TNMG-style inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert firmly into the TNMG pocket and torque the clamp or tighten the center pin according to the toolholder manufacturer specifications. Inspect the insert seat and clamp for chips or debris before securing to ensure proper contact and prevent insert movement during the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG220408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\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: 0.0312 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.8661 inches (22 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\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\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\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P, M, K, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Codes\u003c\/strong\u003e: K, M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 220408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0364 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: 1160285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731895157042,"sku":"1160285","price":196.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db4c681e07df99878e814d0b5e794d1b.jpg?v=1788736219","url":"https:\/\/voomisupply.com\/products\/kennametal-1160285-tnmg432k-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
