Built from solid carbide with a multilayer CVD coating of TiC, TiCN, and TiN, this insert delivers a balanced combination of wear resistance and toughness across a wide range of workpiece materials. The 80-degree diamond (rhombic) insert shape provides strong cutting-edge geometry suitable for turning, facing, and boring. With a 3\/4-inch inscribed circle, 1\/4-inch thickness, and a 1\/32-inch corner radius, it fits standard KENLOC-style toolholders and is held in place by clamp or pin methods. Four usable cutting edges reduce per-edge tooling cost on high-volume production runs.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium machining applications on steel, stainless steel, and cast iron, and also performs in special and super alloy cutting. The neutral hand orientation makes it adaptable across a range of turning setups. Typical use cases include general-purpose OD turning, facing passes, and boring operations in both job-shop and production environments. The chamfered and honed cutting edge style helps manage entry forces and extend tool life on interrupted or continuous cuts. It is a field-replaceable consumable installed by machinists, CNC operators, and toolroom technicians as part of routine insert indexing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade with multilayer CVD TiC\/TiCN\/TiN coating for wear resistance and toughness across steel, stainless, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake and zero-degree relief angle for robust edge strength\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended usable life and lower per-edge cost\u003c\/li\u003e\n\u003cli\u003e1\/32-inch corner radius with chamfered and honed edge prep for controlled entry and reduced chipping\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin holding methods in KENLOC-style toolholders\u003c\/li\u003e\n\u003cli\u003eQualified to ANSI and ISO standards with dual insert codes CNMG642 and CNMG190608\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG642 (ISO: CNMG190608) inserts with clamp or pin holding.

Use the appropriate torque wrench and clamp hardware specified for the KENLOC toolholder to seat the insert securely before resuming cuts. Inspect the insert pocket for chips or debris before seating a new insert. Do not exceed the recommended maximum depth of cut of 0.0492 inches (1.25 mm) for the conditions specified by the toolholder manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG642\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG190608\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Grade\u003c\/strong\u003e: KC850\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: TiC, TiCN, TiN (Multilayer CVD)\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 19.34 mm (0.7616 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3125 inches (7.93 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K), Special and Super Alloys (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0595 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: 1160199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729430479154,"sku":"1160199","price":369.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1266661951abe53d9defe6d4c17875e.jpg?v=1788704542","url":"https:\/\/voomisupply.com\/products\/kennametal-1160199-cnmg642-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
