It carries the KCM25 manufacturer grade, which is engineered for high toughness on steel and moderate wear-resistance and toughness on stainless steel. The insert features a 60-degree triangular shape with a negative rake angle, a neutral hand, and six usable cutting edges. With a 5\/8 inch inscribed circle, 1\/4 inch thickness, and 1\/16 inch corner radius, it fits standard KENLOC-style clamp and pin toolholders. Machinists and CNC operators in production and job-shop environments rely on this insert for roughing and medium machining operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and superalloys including titanium. The RP chip breaker geometry is designed for roughing to medium machining passes where chip control and edge toughness are the primary concerns. It conforms to both ANSI insert code TNMG544 and ISO insert code TNMG270616, making it interchangeable with toolholders designed to either standard. The KCM25 grade targets P-class and M-class workpiece materials and carries a secondary rating for S-class superalloy and titanium applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMTCVD multilayer coating: TiN, TiCN, and Al2O3 for wear resistance and thermal protection\u003c\/li\u003e\n  \u003cli\u003eKCM25 grade rated for high toughness on steel and wear-resistance on stainless steel\u003c\/li\u003e\n  \u003cli\u003eSix cutting edges with chamfered and honed edge prep for consistent entry and extended tool life\u003c\/li\u003e\n  \u003cli\u003eRP chip breaker geometry supports roughing and medium machining chip control\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance design compatible with clamp and pin KENLOC toolholders\u003c\/li\u003e\n  \u003cli\u003eDual-standard compliance: ANSI TNMG544 and ISO TNMG270616\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series clamp and pin toolholders accepting TNMG-style inserts with a 5\/8 inch inscribed circle and 1\/4 inch insert thickness.

The machine spindle must be fully stopped and the toolholder secured in the turret before seating or replacing the insert. Use the correct torx or hex key to tighten the clamp or locking pin to the toolholder manufacturer's specification — do not over-torque. Inspect the insert seat and chip pocket for debris before installing a fresh edge to ensure proper seating and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG544\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG270616\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3 (MTCVD Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 27.50 mm (1.082 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: RP (Roughing, 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 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\u003eMaterial Grade\u003c\/strong\u003e: C1, C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 3761029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732560642354,"sku":"3761029","price":299.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f5a7fdc0b58afaafd2bfcbd049b877c.jpg?v=1788744457","url":"https:\/\/voomisupply.com\/products\/kennametal-3761029-tnmg544rp-kcm25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
