The insert is ground to a 35-degree diamond (rhombic) shape with a positive rake angle of 12 degrees, a 5-degree relief angle, and a honed cutting edge. It measures 16.61 mm (1.3076 inches) in length with a 3\/8-inch inscribed circle diameter and a 1\/64-inch corner radius. The screw-on holding method and neutral hand orientation suit a wide range of turning toolholders. Licensed machinists and CNC operators in production and job-shop environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, boring, back turning, and back boring operations. The MP chip breaker geometry is rated for roughing and medium machining applications. Primary workpiece materials include steel and stainless steel, with the KCM25B grade also suited for superalloys and titanium. Grade characteristics emphasize high toughness on steel (P) workpieces and moderate wear resistance with toughness on stainless steel (M) workpieces. It conforms to ANSI insert code VBMT331 and ISO insert code VBMT160404, making it interchangeable with other inserts meeting those standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN base, Al2O3 mid-layer, TiOCN outer layer for wear resistance on steel and stainless\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker geometry suited for roughing and medium machining depths\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge for improved edge stability in interrupted or variable-feed cuts\u003c\/li\u003e\n  \u003cli\u003eScrew-on mount with 2 usable cutting edges for consistent repeatability at insert change\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI VBMT331 and ISO VBMT160404 standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConforms to ANSI insert code VBMT331 and ISO insert code VBMT160404.

Power down or lock out the machine spindle before seating or removing the insert. Ensure the insert pocket and seating surface are clean and free of chips before torquing the clamping screw to the toolholder manufacturer's specification. Do not exceed the maximum depth of cut of 0.4354 inches for the given workpiece material and machine rigidity conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VBMT331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VBMT160404\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: KCM25B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiCN \/ Al2O3 \/ TiOCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD (CVD)\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\u003eRake Angle\u003c\/strong\u003e: 12 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 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 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (MOQ: 5)\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: 5591786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728902586674,"sku":"5591786","price":222.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b327e4ee0eb046da9f459d6aa083079.jpg?v=1788697551","url":"https:\/\/voomisupply.com\/products\/kennametal-5591786-vbmt331mp-kcm25b-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
