It features a 35-degree diamond (rhombic) insert shape, a neutral hand orientation, and a negative rake angle of 10 degrees. The inscribed circle measures 3\/8 inches, insert length is approximately 1.308 inches (16.61 mm), thickness is 3\/16 inches, and corner radius is 1\/64 inches. With four cutting edges and a honed cutting edge style, this insert delivers high wear-resistance with moderate toughness across multiple turning operations. It is installed by machinists and CNC turning technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is designed for use in turning, facing, boring, back turning, and back boring operations. The KC730 grade targets steel (P), stainless steel (M), and cast iron (K) as primary workpiece materials, with superalloys and titanium listed as secondary applications. The medium machining chip breaker designation makes it well suited for general-purpose material removal at moderate feeds and depths, with a maximum depth of cut of 0.049 inches (1.25 mm). The KENLOC series insert is held in place by clamp and pin methods, which are standard on VNGP-style toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating for high wear-resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e35-degree diamond (rhombic) V-shape with 4 cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003eNegative rake angle (10 degrees) and honed cutting edge for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eMedium machining chip breaker supports turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method compatible with standard VNGP KENLOC toolholders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI (VNGP331) and ISO (VNGP160404) insert geometry standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VNGP-style KENLOC series toolholders that accept clamp and pin insert retention.

Ensure the insert seat and clamp pocket are clean and free of chips before seating the insert. Use the correct torque wrench for the clamp screw as specified by the toolholder manufacturer. Inspect the insert seating and clamp engagement before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNGP331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNGP160404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35-Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInsert Length\u003c\/strong\u003e: 1.308 inches (16.61 mm)\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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 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: 0.049 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\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: Medium Machining\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, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: 0.0216 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: 1160889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734081634610,"sku":"1160889","price":229.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24547b4a5fd0eace27ca1e7cab47151b.jpg?v=1788760810","url":"https:\/\/voomisupply.com\/products\/kennametal-1160889-turning-insert-vngp331k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
