It features a 35-degree diamond (rhombic) insert shape, a 3\/8-inch inscribed circle, and a 1\/32-inch corner radius, making it well suited for precision turning, facing, boring, back turning, and back boring operations. The KC730 grade delivers high wear resistance with moderate toughness across steel, stainless steel, and cast iron workpiece materials. Installation is performed by machinists and toolroom technicians using clamp and pin holding methods in KENLOC-compatible toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in industrial machining environments where consistent surface finish and tool life are priorities. It carries a neutral hand orientation and a negative rake angle of 10 degrees with a negative side clearance, which supports stable chip formation during interrupted and continuous cuts. The K chip breaker geometry and honed cutting edge style contribute to controlled chip flow at shallow-to-moderate depths of cut up to 0.049 inches (1.25 mm). It is applicable to steel (P), stainless steel (M), cast iron (K), and superalloy and titanium (S) workpiece material groups per ISO classification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 PVD TiN-coated solid carbide grade with high wear resistance for steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e35-degree diamond (VNGP) insert shape with 4 cutting edges for extended tool economy\u003c\/li\u003e\n\u003cli\u003eK chip breaker geometry with honed cutting edge for controlled chip flow\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance for stable cutting under clamp and pin holding\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 1.25 mm (0.049 inches)\u003c\/li\u003e\n\u003cli\u003eMulti-use application: turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-compatible toolholders that accept VNGP-style inserts with clamp and pin holding.

Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or clamp screw driver specified by the toolholder manufacturer to secure the clamp and pin; do not overtighten by feel alone. Inspect the insert pocket and seating surfaces for chips or debris before placing a new insert to ensure proper seating and accurate indexing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNGP332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNGP160408\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\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm (0.6537 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.049 inches)\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\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Superalloys and Titanium (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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0209 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: 1160890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746415313202,"sku":"1160890","price":229.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f533f47b08dcd9aa747722635e6a19dc.jpg?v=1788869824","url":"https:\/\/voomisupply.com\/products\/kennametal-1160890-turning-insert-vngp332k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
