Built to ANSI and ISO standards, this insert features an 80-degree diamond shape with a negative rake angle of 13 degrees, a 1\/2-inch inscribed circle, and a 1\/64-inch corner radius. The bright, uncoated carbide construction targets non-ferrous metals and superalloys including titanium, where uncoated substrates typically outperform coated alternatives. With four usable cutting edges and a honed edge style, this insert is intended for use by machinists and CNC operators in production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on non-ferrous workpiece materials and superalloys and titanium. The MS chip breaker geometry controls chip flow during light-to-moderate cutting passes. The CNMG-style insert fits KENLOC-series toolholders that accept the standard clamp-and-pin holding method. Maximum depth of cut is 1.25 mm (0.0492 inches). The insert is sold individually per package, with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide, uncoated (bright finish) K313 grade optimized for non-ferrous metals and superalloys\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with negative rake angle for stable, rigid cutting\u003c\/li\u003e\n  \u003cli\u003eMS chip breaker geometry for controlled chip evacuation on light-to-moderate cuts\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tool life across multiple indexing cycles\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces micro-chipping on difficult materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp-and-pin holding method for secure seating in KENLOC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept CNMG-style inserts with a clamp-and-pin holding method.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before indexing or replacing inserts. Seat the insert firmly against the pocket locating surfaces before engaging the clamp-and-pin mechanism to prevent micro-movement during cutting. Inspect the insert pocket for chips or wear before seating a new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG431MS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K313\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: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 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: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 13 degrees (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: MS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 Material\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys and 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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: 0.022 pounds\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: 2229653\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754331603250,"sku":"2229653","price":158.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71ea8dd2bdb303e99071acef89bf144f.jpg?v=1788944454","url":"https:\/\/voomisupply.com\/products\/kennametal-2229653-turning-insert-cnmg431ms-k313-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
