It carries the KC730 manufacturer grade, which is engineered for high to moderate wear-resistance and toughness across steel, stainless steel, and cast iron applications. The insert features a 90-degree square shape, a 0.5000-inch inscribed circle, a 0.0313-inch corner radius, and a 0.1875-inch thickness. With four cutting edges, a positive rake geometry, and a chamfered and honed cutting edge style, this insert is suited for finishing and medium machining operations. It is installed via screw-on holding method and is intended for use by machinists and CNC turning specialists.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium workpieces. The MF chip breaker geometry makes it well-suited for finishing passes and light to medium material removal where controlled chip formation and surface finish are priorities. The positive side clearance and positive rake angle reduce cutting forces, which is beneficial when machining difficult-to-cut materials. The KC730 grade provides wear-resistance characteristics consistent with P, M, and K workpiece material classifications per ISO standards. Typical applications include external and internal turning on CNC lathes and turning centers in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 grade PVD TiN coating for high to moderate wear-resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eSPMT432MF geometry with MF chip breaker optimized for finishing and medium machining\u003c\/li\u003e\n  \u003cli\u003eFour indexable cutting edges extend tool life per insert\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle and chamfered plus honed edge reduce cutting forces on difficult materials\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method provides secure clamping and repeatable edge positioning\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on style SPMT toolholders conforming to ANSI and ISO mounting standards.

Before indexing or replacing the insert, ensure the machine spindle is fully stopped and the toolholder is secured. Clean the insert pocket and seating surfaces before mounting to ensure proper seating and edge alignment. Follow the toolholder manufacturer torque specifications for the clamping screw, as over-tightening can damage the insert or pocket.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SPMT432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SPMT120408\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\u003eInsert Shape\u003c\/strong\u003e: S - Square\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5000 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: 0.2165 inches\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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF (Finishing \/ 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 Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\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\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\u003eWeight\u003c\/strong\u003e: 0.0168 pounds\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: 1161866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754325705010,"sku":"1161866","price":240.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8db0260cd71ddc1a64052a2a1dc8558f.jpg?v=1788944422","url":"https:\/\/voomisupply.com\/products\/kennametal-1161866-spmt432mf-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
