The insert is manufactured from solid carbide with a PVD-applied TiN coating and features an LF chip breaker geometry for positive-rake, light-finishing applications. It measures 12.9 mm (0.5077 inches) in length with a 0.5-inch inscribed circle and a 1\/32-inch (0.0313-inch) corner radius. The honed cutting edge and screw-on holding method make this insert a practical choice for production turning environments where consistent surface finish and edge security matter. Licensed trades and machinists running CNC lathes or manual turning centers are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on a CNC or manual lathe. Its primary workpiece material classifications cover P (steel), M (stainless steel), and S (superalloys and titanium), with M and S also listed as secondary targets. The 80-degree diamond shape and neutral hand orientation allow versatile positioning in standard CCMT toolholders. Maximum depth of cut is rated at 1.25 mm (0.0492 inches), placing this insert in finishing and light semi-finishing cut ranges. Applications span both shop-floor production and maintenance machining where tight tolerances on difficult materials are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 PVD TiN-coated carbide grade engineered for steel, stainless, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry with positive 5-degree rake angle for light finishing cuts\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Shape Code C) with honed cutting edge for improved edge integrity\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for secure, repeatable seating in compatible CCMT toolholders\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; neutral hand for flexible toolholder orientation\u003c\/li\u003e\n\u003cli\u003eMulti-use application: turning, facing, and boring from a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CCMT screw-on style toolholders accepting a 0.5-inch inscribed circle, 80-degree diamond insert with a 0.2165-inch (5.50 mm) hole diameter. Compliant with ANSI and ISO insert standards. Material grade classifications C2, C3, and C4 apply.

The machine spindle must be fully stopped and the toolholder secured in the turret before indexing or replacing the insert. Use the appropriate Torx or hex key to torque the clamping screw to the toolholder manufacturer's specification — do not over-tighten, as this can fracture the carbide. Inspect the insert seat and screw for debris or damage before seating a new insert edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT432LF\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\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.9 mm (0.5077 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (5.50 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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0192 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: 1161901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737875480882,"sku":"1161901","price":245.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2d4b1f027eb70032fff656a67f25973.jpg?v=1788794737","url":"https:\/\/voomisupply.com\/products\/kennametal-1161901-ccmt432lf-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
