It features a PVD-applied dual coating of TiN and TiAlN, which supports hardness and heat resistance during interrupted and continuous turning operations. The insert measures 11.1 mm (0.437 inches) in length with a 0.25 inch inscribed circle and a 0.016 inch corner radius. The 35-degree diamond shape with positive rake and a 7-degree relief angle makes it suited for moderate to light material removal. Licensed machinists and CNC lathe operators install this insert in standard screw-held toolholders.\u003c\/p\u003e\u003cp\u003eThe VCMT 221-SM geometry targets a broad range of workpiece materials, covering ISO material codes H, K, M, N, P, and S, which correspond to hardened materials, cast iron, stainless steel, non-ferrous alloys, steel, and heat-resistant superalloys respectively. The SM chip breaker design is optimized for finishing and semi-finishing passes. The insert also supports boring applications, making it a multi-use option on CNC lathes and turning centers in both job shop and production environments. Maximum depth of cut is 3.00 mm (0.118 inches).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC907 solid carbide grade with PVD TiN and TiAlN dual coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e35-degree diamond (V) insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle (clearance code C) for edge clearance during turning\u003c\/li\u003e\n\u003cli\u003eSM chip breaker suitable for finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eCompatible with screw-style insert clamping on VCMT-style toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use rating includes both external turning and boring applications\u003c\/li\u003e\n\u003cli\u003eMeets ISO 13399 standards for cutting tool data representation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for VCMT-style screw-held turning toolholders accepting a 221 insert size.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key for the clamping screw and follow the toolholder manufacturer's seating torque guidance. Do not exceed the maximum depth of cut rating for the insert geometry, and inspect the insert seat and screw for wear during each change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VCMT 221-SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN and TiAlN (PVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V), 35-degree included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (0.2500 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.1 mm (0.437 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: 0.016 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.114 inches (2.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.00 mm (0.118 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: H, K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5507352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51729250779442,"sku":"5507352","price":320.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/460bd516bbd23046a9fe20b08a8e6423.jpg?v=1788702219","url":"https:\/\/voomisupply.com\/products\/iscar-5507352-turning-insert-vcmt221sm-ic907-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
