It carries the ANSI designation VNGG3305 and ISO designation VNGG160402, featuring a 35-degree diamond (rhombic) shape with a neutral hand orientation. The insert is PVD-coated with TiN and ground to G tolerance, delivering consistent dimensional accuracy. The LF chip breaker geometry is optimized for finishing and light machining passes, and the KC730 grade provides high wear resistance across a range of workpiece materials. With four cutting edges and a honed cutting edge style, this insert offers good tool economy for production environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring applications on steel, stainless steel, cast iron, and superalloys including titanium. It fits toolholders designed for VNGG-style inserts with negative rake and negative side clearance, using clamp or pin holding methods. Typical applications include finishing passes and light roughing on ferrous and difficult-to-machine alloys in aerospace, general machining, and manufacturing environments. The KC730 grade is rated for high to moderate wear resistance and toughness across steel (P), stainless steel (M), and cast iron (K) workpiece categories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-degree diamond (rhombic) insert shape provides a sharp, low-force cutting geometry suited to finishing operations\u003c\/li\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating offers high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry targets finishing and light machining, controlling chip flow at lower depths of cut\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for improved cost per edge\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance design for use in rigid, stable toolholding systems\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods per ANSI and ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VNGG-style turning toolholders that accept ANSI size code 3305 inserts with negative rake and pin or clamp retention.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and torque the clamping screw or pin per the toolholder manufacturer's specification. Inspect the insert seat and chip breaker pocket for debris or damage before seating a new edge to ensure accurate positioning and safe operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNGG3305\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNGG160402\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\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\u003eCoating\u003c\/strong\u003e: TiN (PVD)\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\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm \/ 1.3076 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (1\/128 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees negative\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: Clamp \/ Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: 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\u003eWeight\u003c\/strong\u003e: 0.0238 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: 1160861\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732664582450,"sku":"1160861","price":209.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a34e74f15c337c74b78188a282a42f1.jpg?v=1788745493","url":"https:\/\/voomisupply.com\/products\/kennametal-1160861-turning-insert-vngg330-5lf-kc730","provider":"Voomi Supply","version":"1.0","type":"link"}
