It features an 80-degree diamond shape with a neutral hand orientation, making it a versatile choice for turning, facing, and boring operations. The insert carries a positive rake angle of 5 degrees, a clearance code of C, and a tolerance code of M. With a honed cutting edge style and a corner radius of 0.0079 inches, it delivers consistent performance in demanding applications. Installation is via screw-on holding method. Licensed HVAC, plumbing, or general machining trades handling precision metalwork will find this insert suited to production-level turning setups.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for use on stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material codes M and S. It is appropriate for both light and moderate-depth passes, with a maximum depth of cut of 0.0492 inches (1.25 mm). The screw-on series design suits standard toolholders configured for CCMT-style inserts. Typical applications include turning, facing, and boring on CNC lathes and manual turning centers in both production shop and job shop environments. Each insert provides 2 cutting edges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 grade TiAlN-coated carbide with PVD coating process for wear resistance on difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for edge stability in stainless steel and superalloy cuts\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eMulti-use capability: turning, facing, and boring from a single insert\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw-on replacement insert for toolholders accepting CCMT21505 geometry inserts.

Seat the insert fully in the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the insert seat and clamping surfaces for chips or debris before seating. Index to the second cutting edge only after the first edge shows wear; do not attempt to re-grind carbide inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT21505LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\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: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2539 inches (6.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (1\/128 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches (2.80 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\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium (ISO M, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0024 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: 2425659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740866412850,"sku":"2425659","price":179.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f97dbd8d05aaec90cd69b06a96e9974.jpg?v=1788827980","url":"https:\/\/voomisupply.com\/products\/kennametal-2425659-turning-insert-ccmt21505lf-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
