It features a multilayer TiCN and Al2O3 MTCVD coating applied via CVD process, delivering wear resistance suited to steel and stainless steel machining. The insert carries an 80-degree diamond (rhombic) shape, a positive rake geometry, and an 11-degree relief angle. With a 0.25-inch inscribed circle and a 0.03-inch corner radius, this screw-on insert is sized for finish to medium machining operations. Licensed HVAC techs and machinists in metalworking shops will recognize the MF chip breaker as a geometry optimized for controlled chip formation at moderate feeds and depths.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium workpieces. The KCM15B grade provides moderate wear resistance combined with toughness, making it a practical choice for both P-class (steel) and M-class (stainless steel) ISO material groups. It is suited to CNC turning centers and manual lathes where screw-on toolholders accepting CPMT-style inserts are used. A maximum depth of cut of 0.08 inches supports light-to-moderate roughing passes as well as finishing cuts. Two cutting edges are available per insert, improving cost-per-edge economics in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with multilayer TiCN and Al2O3 CVD coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake and positive side clearance\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry optimized for finishing and medium machining applications\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method with chamfered and honed cutting edge style for controlled entry\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert for extended tool life per piece\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI insert code CPMT2152 and ISO insert code CPMT060208\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw-on turning insert conforming to ANSI code CPMT2152 and ISO code CPMT060208, compatible with standard CPMT-style screw-on toolholders used in turning, facing, and boring applications on steel, stainless steel, superalloys, and titanium workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machining professionals using appropriate CPMT screw-on toolholders; ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or replacing the insert. Inspect the pocket seating surface and shim for chips or debris before installing the new insert. Follow the toolholder manufacturer torque guidelines for the clamping screw to avoid fracturing the carbide substrate. Verify insert orientation and hand designation match the toolholder before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT2152\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT060208\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: KCM15B\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: MF (Finishing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.45 mm (0.2539 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0845 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\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\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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and 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\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\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: 0.01 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: 5641069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731111706930,"sku":"5641069","price":185.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cea0b3985fde2d6a1867e2188f70ecae_ed53c75b-9610-4d99-96be-f37a10762586.jpg?v=1788727085","url":"https:\/\/voomisupply.com\/products\/kennametal-5641069-turning-insert-cpmt2152mf-kcm15b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
