The insert is manufactured from solid carbide and features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied via MTCVD process, providing wear resistance and thermal stability during cutting. The diamond 80-degree included angle and positive rake geometry deliver efficient chip control across a range of workpiece materials. With a 3\/8-inch inscribed circle, a 1\/32-inch corner radius, and an insert length of 9.67 mm (0.3808 inches), this insert fits standard CCMT screw-on toolholders and suits applications where consistent edge life is a priority.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium. The LF chip breaker geometry is suited for light to moderate cutting depths, with a maximum depth of cut of 1.25 mm (0.0500 inches). It is a neutral-hand insert, making it usable in both right-hand and left-hand toolholders. Licensed machinists, CNC operators, and toolroom technicians working in production or job-shop environments are the primary users. Applications span general turning on lathes and turning centers where controlled chip formation on difficult-to-machine materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCM25 grade with multilayer CVD TiN\/TiCN\/Al2O3 coating for extended tool life on steel and stainless\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry optimized for light finishing cuts and controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 5 degrees reduces cutting forces on difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDiamond 80-degree insert shape (CCMT) provides two cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method ensures secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards for interchangeable fitment in standard CCMT insert pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CCMT screw-on toolholders conforming to ANSI and ISO insert pocket specifications for the CCMT3252 insert size.

Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the appropriate torx or hex key to tighten the clamping screw to toolholder manufacturer specifications  -  do not overtighten, as this can fracture the carbide. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper edge indexing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: CCMT3252LF\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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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\/32 inch (0.0313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0500 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\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\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\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3 (Multilayer CVD \/ MTCVD)\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 3758089\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744467583282,"sku":"3758089","price":212.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e06573bfe6190416e23a9f63932f67f.jpg?v=1788856902","url":"https:\/\/voomisupply.com\/products\/kennametal-3758089-ccmt3252lf-kcm25-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
