It carries the KC730 manufacturer grade, which is engineered for high to moderate wear resistance across steel, stainless steel, and cast iron workpiece materials. The insert features a 35-degree diamond (rhombic) shape, a neutral hand orientation, a 0.2500-inch inscribed circle, and a 0.0079-inch corner radius. The LF chip breaker geometry targets finishing and light machining operations. Mounting is via screw-on method, with positive rake and positive side clearance supporting clean, controlled chip formation in demanding turning applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external and internal turning, facing, boring, back turning, and back boring on CNC lathes and turning centers. Its KC730 grade and TiN PVD coating make it particularly effective when machining steel (P-class), stainless steel (M-class), and cast iron (K-class) materials. Secondary suitability extends to superalloys and titanium (S-class). The finishing-oriented LF chip breaker is appropriate for final-pass and close-tolerance work where surface finish and dimensional accuracy are priorities. Two cutting edges are available per insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 grade with TiN PVD coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (V-shape) insert geometry with honed cutting edge style\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker designed for finishing and light machining passes\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method compatible with VBMT-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use capability: turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VBMT-style screw-on toolholders.

Seat the insert fully in the pocket and torque the clamping screw according to the toolholder manufacturer specification before returning to cutting conditions. Inspect the insert pocket and seating surface for chips or debris before each insert change to maintain positional accuracy. Dispose of worn inserts per applicable facility and local regulations for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VBMT2205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VBMT110302\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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF (Finishing \/ Light Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.70 mm \/ 0.8718 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (1\/128 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches (2.80 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\u003eRelief Angle\u003c\/strong\u003e: 5 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\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 Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: B\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: Superalloys, Titanium\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: 0.0057 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: 1161971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51745456423218,"sku":"1161971","price":250.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1481d66e63f002c96678e3db50f777b7.jpg?v=1788864128","url":"https:\/\/voomisupply.com\/products\/kennametal-1161971-turning-insert-vbmt220-5lf-kc730","provider":"Voomi Supply","version":"1.0","type":"link"}
