It carries an inscribed circle of 0.25 inches, an insert length of 11.00 mm (0.4331 inches), a thickness of 0.125 inches, and a corner radius of 1\/64 inches (0.0156 inches). The KC730 grade is engineered for high wear-resistance to moderate wear-resistance and toughness across steel, stainless steel, and cast iron workpiece materials. This insert is held by screw and features a positive side clearance with an 11-degree relief angle. It is specified and installed by machinists and CNC turning technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning operations on steel (P), stainless steel (M), and cast iron (K) workpieces, with secondary application in heat-resistant superalloys (S). The maximum depth of cut is 1.25 mm (0.0492 inches), making it appropriate for finish to light-medium turning passes. It is a neutral-hand insert, compatible with toolholders designed for TCMT-style seating, and is identified by industry standard number TCMT3251LF. Typical applications include close-tolerance diameter turning, facing, and light profiling where surface finish and tool life consistency are the priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 PVD TiN coating delivers high wear-resistance with retained toughness on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape (ANSI code T221, ISO code T110304) provides three usable cutting edges\u003c\/li\u003e\n\u003cli\u003e0.0156-inch corner radius suited for finish turning with controlled surface finish\u003c\/li\u003e\n\u003cli\u003ePositive side clearance and 11-degree relief angle reduce cutting forces and edge buildup\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method ensures repeatable seating and edge indexing\u003c\/li\u003e\n\u003cli\u003eIndustry standard number TCMT3251LF for direct cross-reference to equivalent toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eIdentified by industry standard number TCMT3251LF; designed for toolholders accepting TCMT-style screw-lock turning inserts.

Use the appropriate Torx or hex key to the toolholder manufacturer's specified screw procedure when clamping the insert screw. Inspect the insert pocket for chips or debris before seating each new edge. Disposal of carbide inserts should follow applicable shop waste and recycling protocols for tungsten carbide materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: T221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: T110304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TCMT3251LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle, 60 degrees included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.00 mm (0.4331 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\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\u003eHole Diameter\u003c\/strong\u003e: 0.0945 inches (2.40 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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P, M, K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Codes\u003c\/strong\u003e: M, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0044 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: 1160929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748050370866,"sku":"1160929","price":160.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad05849c74bbe25e44d9356939f46960.jpg?v=1788888485","url":"https:\/\/voomisupply.com\/products\/kennametal-1160929-turning-insert-t221s-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
