The insert is solid carbide with a multilayer CVD coating of TiC, TiCN, and TiN, which provides a balance of wear resistance and toughness across a range of workpiece materials. It carries a neutral hand orientation, a 0.0156-inch corner radius, and an inscribed circle of 0.375 inches. The 60-degree included angle and negative rake geometry make it well suited for interrupted and continuous cuts where edge stability is critical. This insert is part of the KENLOC series and is sold individually with a minimum order of 5 pieces.\u003c\/p\u003e\n\u003cp\u003eThe 1160292 is designed for turning, facing, and boring operations on steel, stainless steel, and cast iron, as well as special and super alloys. Its KC850 grade characteristics span moderate wear resistance and toughness to high toughness across ISO material groups P, M, K, and S. Typical applications include medium machining operations in production shops, job shops, and aerospace or general manufacturing environments where a versatile carbide grade is preferred. The insert delivers 6 cutting edges per piece, reducing per-edge tooling cost in high-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 grade with multilayer CVD TiC, TiCN, and TiN coating for wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003e6 cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation — compatible with both right-hand and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance (clearance code N) for strong, stable cutting edge\u003c\/li\u003e\n  \u003cli\u003eMedium chip breaker geometry suited for medium-depth finishing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eDual holding method: clamp and pin, compatible with KENLOC-style toolholders\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for reduced built-up edge on steel and stainless\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept TNMG-style negative-rake triangular inserts with clamp and pin retention.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate KENLOC clamp screw and torx or hex key as specified by the toolholder manufacturer — do not overtighten the clamp, as this can fracture the carbide body. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG321\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG160304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\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 (Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 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\u003eInsert Length\u003c\/strong\u003e: 16.50 mm (0.6495 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative rake geometry)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\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, Stainless Steel, Cast Iron, Special and Super Alloys (ISO P, M, K, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 0.0099 pounds\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: 1160292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732664254770,"sku":"1160292","price":128.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d52a257550c7a2b04264c59a1bfc92fc.jpg?v=1788745490","url":"https:\/\/voomisupply.com\/products\/kennametal-1160292-turning-insert-tnmg321-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
