The insert features a multilayer CVD coating stack of TiCN, Al2O3, and TiOCN applied through an MTCVD process, which delivers high toughness against steel and moderate wear-resistance and toughness against stainless steel. It has a 35-degree diamond (rhombic) shape with a negative rake angle of 6 degrees, a negative side clearance, and a chamfered and honed cutting edge style. Four usable cutting edges are available per insert. The MP chip breaker geometry targets roughing and medium machining operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations in both job shop and production environments. Primary workpiece materials are steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P and M. The KENLOC series designation indicates compatibility with KENNAMETAL clamp and pin-style toolholders designed for VNMG geometry inserts. It is appropriate for moderate to heavy material removal rates where edge toughness and coating adhesion under interrupted or scaled cuts are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCM25B grade with multilayer CVD TiCN \/ Al2O3 \/ TiOCN coating for steel and stainless steel applications\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape (V) with negative rake and negative side clearance for secure clamping\u003c\/li\u003e\n\u003cli\u003eMP chip breaker designed for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert, compatible with clamp and pin holding methods\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut up to 0.4354 inches\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI insert code VNMG332 and ISO insert code VNMG160408\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENNAMETAL KENLOC series clamp and pin-style toolholders accepting VNMG geometry inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench for the clamping screw and inspect the insert pocket for chips or wear before seating a new insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMG332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMG160408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM25B\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN \/ Al2O3 \/ TiOCN (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MP (Roughing and Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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 (1.3076 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\u003eWidth\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4354 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 6 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, 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\u003eMaterial Grade\u003c\/strong\u003e: C1, C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 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: 5591781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731115245874,"sku":"5591781","price":223.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dad395a3122734d46e37610ef082b46e_703bbce3-baba-402b-ad96-7b077f8b786a.jpg?v=1788727136","url":"https:\/\/voomisupply.com\/products\/kennametal-5591781-vnmg332mp-turning-insert-kcm25b","provider":"Voomi Supply","version":"1.0","type":"link"}
