It carries a PVD-applied TiN coating under the KC730 grade, which delivers high wear resistance across a range from moderate to demanding cutting conditions. The insert features an 80-degree diamond (rhombic) shape, a positive rake angle of 15 degrees, and an 11-degree relief angle, making it well suited for light, accurate passes where surface finish and dimensional control are the priority. The HP chip breaker geometry is optimized for finishing cuts, and the screw-on holding method provides secure, repeatable seating in compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring operations on steel, stainless steel, and cast iron workpieces, with secondary capability on superalloys and titanium. The KC730 grade is rated for high wear resistance to moderate wear resistance and toughness across P, M, and K material classifications. It is a neutral-hand insert, fitting either left- or right-hand toolholder pockets of the appropriate style. Licensed machinists and CNC operators in job shop, production, and maintenance turning environments are the typical installers. The 0.3808-inch insert length and 0.375-inch inscribed circle place it in a common mid-small size range for precision finishing work.\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 and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake for reduced cutting forces during finishing\u003c\/li\u003e\n  \u003cli\u003eHP chip breaker geometry optimized for finishing chip control and surface quality\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for consistent edge integrity on finish passes\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; neutral hand for versatile toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.0492 inches (1.25 mm) per finishing application guidelines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CPGT-style screw-on turning toolholders accepting a 3\/8-inch inscribed circle (ANSI size code 3251, ISO size code 09T304).

Always power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified for the toolholder screw to avoid stripping the insert pocket; do not overtighten, as this can crack the carbide insert body. Inspect the toolholder pocket and seating surface for chips or debris before seating the new insert to ensure proper support and accurate geometry presentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPGT3251\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPGT09T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CPGT\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\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HP (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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 Length\u003c\/strong\u003e: 0.3808 inches (9.67 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel (M), Superalloys and Titanium (S)\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0115 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 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: 1161911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734046441778,"sku":"1161911","price":235.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9bbc1e5b12ee6de1e922445bcbba601.jpg?v=1788760651","url":"https:\/\/voomisupply.com\/products\/kennametal-1161911-turning-insert-cpgt-tin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
