The 80-degree diamond (rhombic) shape provides a positive rake angle and 11-degree relief angle, contributing to stable cutting performance during turning, facing, and boring operations. The MW chip breaker is engineered for medium machining applications with a wiper edge geometry that improves surface finish at standard feed rates. At 9.67 mm in length and 0.375 inches inscribed circle, this insert fits screw-on toolholders and delivers two usable cutting edges per insert. Installation and application are handled by machinists and CNC turning center operators in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and cast iron workpieces in both residential shop and industrial production settings. The KCP25 grade provides moderate wear resistance combined with toughness, making it appropriate for general-purpose steel (P) and aluminum and non-ferrous (N) material groups. The positive side clearance and chamfered, honed cutting edge style reduce cutting forces and edge chipping during interrupted or continuous cuts. Typical applications include external and internal turning, facing passes, and light boring where consistent surface finish and tool life predictability are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP25 grade with multilayer TiCN and Al2O3 CVD coating for moderate wear resistance and toughness across P and N material groups\u003c\/li\u003e\n  \u003cli\u003eMW wiper chip breaker optimized for medium machining with improved surface finish at standard feed rates\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with positive rake and 11-degree relief angle for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert with chamfered and honed edge prep for edge stability\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method compatible with standard CPMT-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inches) suited for finishing and semi-finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on CPMT-style turning toolholders conforming to ANSI and ISO standards for the CPMT3252 (ISO 09T308) insert seat size.

Always index or replace inserts with the machine spindle stopped and the machine in a locked-out, zero-energy state per applicable shop safety procedures. Use the correct screw torque driver specified by the toolholder manufacturer to avoid cracking the carbide insert or stripping the clamp screw. Inspect the toolholder pocket for chips or damage before seating a new insert to ensure proper contact and repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT3252\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT09T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 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\u003eManufacturer Grade\u003c\/strong\u003e: KCP25\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: TiCN and Al2O3 Multilayer CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MW (Wiper - Medium Machining)\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 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: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive rake geometry)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: Yes\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, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\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  \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: 3751620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744674382130,"sku":"3751620","price":211.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f354c6012c17370fea5554f18f695ab9_d0ff078c-eee0-4e00-aa38-0f19507a6b2e.jpg?v=1788859850","url":"https:\/\/voomisupply.com\/products\/kennametal-3751620-cpmt3252mw-kcp25-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
