It features an 80-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and a 7-degree relief angle. The LF chip breaker geometry is optimized for finishing and light machining operations. With an inscribed circle of 0.375 inches and a corner radius of 0.0156 inches, the insert delivers tight tolerances and sharp, honed cutting edges on two usable cutting positions. Licensed machinists and CNC turning specialists install this insert in screw-on toolholders for production and precision turning applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and cast iron workpieces where high wear resistance is the primary requirement. The cermet base material combined with PVD multilayer coating delivers consistent tool life at finishing depth-of-cut levels, with a maximum depth of cut of 1.25 mm (0.0492 inches). It carries both ANSI designation CCMT3251 and ISO designation CCMT09T304, making it compatible with standard CCMT-style screw-on toolholders used throughout CNC and manual turning centers in residential shop, job shop, and production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKT315 cermet substrate with multilayer PVD TiN\/TiCN\/TiN coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry engineered for finishing and light machining cuts\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (ANSI code C) with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style improves edge stability and surface finish consistency\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert extend usable tool life per unit\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI CCMT3251 and ISO CCMT09T304 standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CCMT-style screw-on toolholders conforming to ANSI CCMT3251 and ISO CCMT09T304 specifications.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and screw size specified by the toolholder manufacturer when securing the screw-on insert to avoid seat damage or insert cracking. Do not exceed the maximum depth of cut specified for this insert geometry, as over-engagement during finishing operations can cause premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT3251\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT3251LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KT315\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN \/ TiCN \/ TiN Multilayer PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF (Finishing \/ Light Machining)\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: 9.67 mm (0.3808 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 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: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C7\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: 0.022 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: 1869967\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734259826994,"sku":"1869967","price":198.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/187684d54cd7e4026094a4480fba0d89.jpg?v=1788761629","url":"https:\/\/voomisupply.com\/products\/kennametal-1869967-turning-insert-ccmt3251lf-kt315-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
