Designated CCMT3252MF under the ANSI standard and CCMT09T308 under ISO, this insert features an 80-degree diamond (rhombic) shape with a positive rake angle and a 7-degree relief angle. The KC730 grade uses a PVD-applied TiN coating to deliver high wear resistance while maintaining edge toughness. With a 0.375 inch inscribed circle, a 0.03125 inch corner radius, and an MF chip breaker geometry, this insert is optimized for finishing and medium machining passes. Licensed HVAC techs, plumbers, and machinists familiar with indexable tooling will recognize this as a screw-on style insert with two usable cutting edges.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and cast iron. The KC730 grade characteristics cover Steel (P), Stainless Steel (M), and Cast Iron (K) workpiece materials, ranging from high wear resistance to moderate toughness. Superalloys and titanium are listed as secondary workpiece materials. The MF chip breaker geometry targets finishing and medium machining cuts, making this insert appropriate for close-tolerance work where surface finish and dimensional accuracy are priorities. It is installed in CCMT-style screw-on toolholders compatible with the 3252 size code.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond insert shape (CCMT) with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating for high wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eMF chip breaker geometry optimized for finishing and medium machining passes\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; neutral hand for flexible toolholder orientation\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for secure, repeatable seating in the toolholder pocket\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO dimensional standards (CCMT3252 \/ CCMT09T308)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CCMT3252-compatible screw-on turning toolholders.

Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the toolholder pocket and screw for wear or damage before seating a new insert. Do not overtighten the clamping screw, as this can crack the carbide substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT3252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T308\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\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (PVD Process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF (Finishing \/ Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.03125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.67 mm (0.3808 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\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: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 0.0077 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: 1161843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733428470066,"sku":"1161843","price":219.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/021a4a954efa438b35b362f5a5e3fef9.jpg?v=1788755459","url":"https:\/\/voomisupply.com\/products\/kennametal-1161843-ccmt3252mf-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
