It carries the ANSI designation VNMS332 and ISO designation VNMS160408. The insert features a 35-degree diamond (rhombic) shape with a neutral hand orientation and a TiN PVD coating applied over a KC730 carbide grade substrate. With an inscribed circle of 0.375 inches, an insert length of 16.61 mm (approximately 0.654 inches), and a corner radius of 0.0313 inches (1\/32 inch), this insert is suited for medium machining chip-breaker applications. Licensed machinists and CNC operators install this insert on compatible KENLOC toolholders for turning, facing, boring, back turning, and back boring operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for primary use on steel, stainless steel, and cast iron workpieces, with secondary suitability for superalloys and titanium. It performs across high wear-resistance to moderate wear-resistance and toughness ranges for each of those material categories. The KC730 grade with TiN PVD coating delivers consistent edge life across finishing and semi-finishing passes in both manual and CNC turning centers. The four available cutting edges make the insert cost-effective for production environments where tool change frequency must be managed closely. It is appropriate for both horizontal and vertical turning machine setups where a VNMS-style pocket is present.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI code VNMS332 \/ ISO code VNMS160408 for direct cross-referencing in standard toolholder catalogs\u003c\/li\u003e\n  \u003cli\u003eKC730 grade with TiN PVD coating provides high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape allows access into tight contours and profiling cuts\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum yield per unit\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle and honed cutting edge style reduce edge chipping on interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods for secure seating in KENLOC pockets\u003c\/li\u003e\n  \u003cli\u003eMedium machining chip breaker geometry suits a wide range of feed and depth-of-cut combinations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC series toolholders accepting VNMS-style insert pockets with clamp or pin retention.

Always index or replace the insert with the machine powered down and the spindle locked. Seat the insert fully into the KENLOC pocket before applying clamping force to avoid micro-fracture at the cutting edge. Inspect the pocket seat and clamping screw or pin for wear each time the insert is indexed to maintain consistent tool-tip positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMS332\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMS160408\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\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\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: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm (0.654 inches approximate)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: 0.0492 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: 20 degrees (negative rake)\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: Common (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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\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: 0.2734 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: 1160921\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747238543666,"sku":"1160921","price":240.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1975121c22d521717669b7162896461.jpg?v=1788877974","url":"https:\/\/voomisupply.com\/products\/kennametal-1160921-turning-insert-vnms332-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
