It features an 80-degree diamond (rhombic) shape with a negative rake and zero-degree relief angle, giving the cutting geometry four usable cutting edges. The KC730 grade carries a PVD-applied TiN coating engineered for high to moderate wear resistance across steel, stainless steel, and superalloy workpiece materials. Insert length is 12.90 mm (0.5077 inches), inscribed circle is 0.5 inches, thickness is 0.1875 inches, and corner radius is 0.0313 inches. Part of the KENLOC series.\u003c\/p\u003e\n\u003cp\u003eThe 1160872 is suited for medium machining applications in both production and job-shop environments. Its primary workpiece materials are steel, stainless steel, and superalloys including titanium, with secondary suitability for additional stainless and superalloy grades. The neutral hand orientation makes it compatible with both standard and live-tooling setups. Typical applications include external turning, face turning, and boring where consistent tool life and dimensional accuracy on difficult-to-machine alloys are required. Maximum depth of cut is 1.25 mm (0.0492 inches), making this insert well-matched to finishing and light semi-finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 grade with PVD TiN coating for high wear resistance on steel, stainless steel, and superalloys\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (CNMP) insert shape provides four cutting edges and strong nose strength\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces micro-chipping on difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003eNegative rake and zero-degree relief angle (clearance code N) for stable interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eCommon chip breaker geometry optimized for medium machining chip control\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin insert holding methods per KENLOC toolholder design\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO insert standards; UNSPSC 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMP432 (ANSI) or CNMP120408 (ISO) turning inserts with clamp and pin holding.

Before changing inserts, shut down spindle rotation and verify the machine is in a safe, locked-out state per shop lockout\/tagout procedures. Seat the insert fully against the toolholder pocket locating surfaces and tighten the clamp or pin fastener to the toolholder manufacturer's specification — do not over-tighten, as carbide inserts are brittle and can crack under uneven clamping load. Inspect the pocket and seating surfaces for chips or debris before each insert index.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMP432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMP120408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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: 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: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (PVD)\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: Common (Medium Machining)\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 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: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: 0.0201 pounds\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\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: 1160872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737009848626,"sku":"1160872","price":180.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe5a91d25c782d344d77738e30115400.jpg?v=1788783123","url":"https:\/\/voomisupply.com\/products\/kennametal-1160872-cnmp432-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
