It carries an 80-degree diamond (rhombic) shape, a 3\/8-inch inscribed circle, and a 1\/64-inch corner radius. The KC5010 grade delivers high wear resistance to moderate wear resistance with toughness across steel, stainless steel, and superalloy workpiece materials. This is a finishing-geometry insert intended for turning, facing, and boring operations. It is installed and indexed by licensed machinists and CNC operators on production and job-shop lathes. Each insert provides four usable cutting edges, making it an efficient choice for high-volume finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for precision finishing cuts on steel, stainless steel, cast iron, superalloys, titanium, and aluminum. It fits KENLOC-style toolholders that accept CNMG-configuration inserts with a clamp-and-pin holding method. The neutral hand orientation makes it compatible with standard right-hand and left-hand toolholder setups where CNMG geometry is specified. Typical applications include shaft turning, facing shoulders, and finish boring on CNC lathes and turning centers in both residential machine shops and industrial production environments. Maximum depth of cut is 1.25 mm (0.0492 inches), consistent with a finishing-grade geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC5010 grade with PVD TiAlN coating for high wear resistance on steel, stainless steel, and superalloys\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape provides a strong cutting edge with good accessibility\u003c\/li\u003e\n  \u003cli\u003eFF chip breaker geometry optimized for finishing operations\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert reduce per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eClamp-and-pin holding method compatible with KENLOC-series toolholders\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces microchipping on difficult materials\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation suits a wide range of CNMG toolholder configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG321 inserts with clamp-and-pin mounting.

Always index or replace inserts with the machine fully stopped and the spindle locked. Use the appropriate torque wrench and seating pin for the KENLOC clamp system to ensure proper insert seating and prevent movement under cutting load. Inspect the insert pocket and clamp for wear or debris before seating a new insert, as contamination can cause premature edge failure or dimensional inaccuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG321\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG090304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG321FF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\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\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.67 mm (0.3808 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches (3.81 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\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FF (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 degrees (Negative Rake)\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\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\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\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\u003eWeight\u003c\/strong\u003e: 0.0071 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1624156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742340088114,"sku":"1624156","price":271.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1696d0c7a95cae4ad9b84ce16ddee5fd.jpg?v=1788836861","url":"https:\/\/voomisupply.com\/products\/kennametal-1624156-turning-insert-cnmg321ff-kc5010","provider":"Voomi Supply","version":"1.0","type":"link"}
