The insert features a square shape with a 90-degree included angle, a 0.5-inch inscribed circle, and a 1\/32-inch (0.0313 inch) corner radius. The KC730 grade uses a PVD-applied TiN coating that provides high wear resistance while maintaining toughness across a range of workpiece materials. The LF chip breaker geometry is optimized for finishing and light machining operations. This insert uses a screw-on holding method and delivers four usable cutting edges per insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing and light machining passes on steel, stainless steel, and cast iron. The positive rake angle of 5 degrees and honed cutting edge style reduce cutting forces and help produce consistent surface finishes at controlled depths. The maximum depth of cut is 0.0492 inch (1.25 mm), placing this insert firmly in finishing-pass territory. It is appropriate for both CNC and manual turning setups where the tool holder accepts screw-on SPGT-style inserts. Machinists working with superalloys and titanium will also find the KC730 grade suitable based on its wear-resistance and toughness profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 PVD TiN-coated solid carbide grade with high wear resistance for steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for finishing and light machining cuts\u003c\/li\u003e\n\u003cli\u003e90-degree square insert shape (SPGT) with positive rake and positive side clearance\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eScrew-on mounting method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards (ANSI: SPGT432, ISO: SPGT120408)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on SPGT-style tool holders that accept a 0.5-inch inscribed circle square insert with a 0.2165-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Do not exceed the maximum depth of cut rating for this geometry during finishing operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SPGT432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SPGT120408\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 (PVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inch (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light 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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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, 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0148 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: 1161879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730051367218,"sku":"1161879","price":254.41,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1eebe821cbf010bc0a80de8f7af233b.jpg?v=1788710827","url":"https:\/\/voomisupply.com\/products\/kennametal-1161879-spgt432lf-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
