The grade is KCM25B, engineered for high toughness in steel and moderate wear-resistance and toughness in stainless steel machining. The insert features a 90-degree square shape, a 5\/8-inch inscribed circle, a 3\/64-inch corner radius, and a 1\/4-inch thickness. With 8 cutting edges and a neutral hand orientation, it offers cost-effective edge utilization in high-volume production environments. Licensed machinists and CNC operators install this insert in compatible toolholders for external and internal turning applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for roughing and medium machining operations on steel, stainless steel, superalloys, and titanium. It supports multi-use applications including turning, facing, and boring. The negative rake and negative side clearance geometry, combined with chamfered and honed cutting edges, provide stable cutting action and controlled chip formation under interrupted and continuous cuts. It is identified by ANSI insert code SNMG543 and ISO insert code SNMG150612, and conforms to both ANSI and ISO standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiOCN for wear resistance and toughness across steel and stainless steel grades\u003c\/li\u003e\n  \u003cli\u003e8 cutting edges with negative rake and negative side clearance for stable, rigid clamping\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker designed for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for edge strength and reduced chipping risk\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; dual-coded SNMG543 and SNMG150612\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SNMG-style KENLOC toolholders accepting a 5\/8-inch inscribed circle square insert with a 1\/4-inch thickness and 3\/64-inch corner radius.

Power down and lock out the machine spindle before seating or indexing the insert. Secure the insert using the appropriate clamp or pin holding method specified for the toolholder; do not exceed the toolholder manufacturer's clamping torque recommendation. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper seating and dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNMG543\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNMG150612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square, 90-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: KCM25B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiOCN (Multilayer CVD, MTCVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.88 mm (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2081 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\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\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 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: 5591954\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731620528434,"sku":"5591954","price":256.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee71fc3d1518fb42864189d1b501590f.jpg?v=1788733252","url":"https:\/\/voomisupply.com\/products\/kennametal-5591954-snmg543mp-turning-insert-kcm25b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
