It carries the ANSI insert code CPMT2152MF and grade designation KCM25B, with a multilayer CVD coating consisting of TiCN, Al2O3, and TiOCN applied via MTCVD process. The 80-degree diamond (rhombic) shape provides a strong cutting geometry suited to finishing and medium machining passes. With a 0.25-inch inscribed circle, a 0.0313-inch corner radius, and a positive rake and side clearance geometry, this insert delivers controlled chip formation and surface finish on steel, stainless steel, superalloys, and titanium workpieces. Licensed machinists, CNC programmers, and toolroom techs specify this insert for turning, facing, and boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is targeted at production and job-shop environments where steel (P-group) and stainless steel (M-group) are primary workpiece materials. The KCM25B grade balances high toughness for steel with moderate wear resistance for stainless, making it a practical choice across a range of material conditions. The MF chip breaker geometry supports finishing and medium-depth passes with a maximum depth of cut of 0.0845 inches. It mounts via screw-on (screw-in) holding method, compatible with CPMT-style toolholders. The neutral hand orientation suits straight turning and facing tool paths without requiring a dedicated left- or right-hand holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code CPMT2152MF, ISO code CPMT060208 for global toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eKCM25B grade with multilayer CVD TiCN \/ Al2O3 \/ TiOCN coating for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with chamfered and honed cutting edge for controlled entry and edge strength\u003c\/li\u003e\n\u003cli\u003eMF chip breaker optimized for finishing and medium machining on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003ePositive rake and positive side clearance geometry reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with 0.1102-inch hole diameter for positive insert seating\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert; neutral hand for flexible toolholder use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for CPMT2152MF-style screw-on turning insert seats.

Disengage machine power and confirm the spindle is fully stopped before indexing or replacing inserts. Use the manufacturer-specified torque wrench for the insert clamping screw to avoid over-torquing the screw or cracking the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT2152MF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT060208\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM25B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 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\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2539 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 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\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\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing; Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered; Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN \/ Al2O3 \/ TiOCN (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\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, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Characteristics\u003c\/strong\u003e: Steel (P) - High Toughness; Stainless Steel (M) - Moderate Wear Resistance and Toughness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI; ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1; C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.0661 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: 5591711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733678227762,"sku":"5591711","price":185.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cea0b3985fde2d6a1867e2188f70ecae_9bf76512-a711-4afc-92b1-b517ed0d7261.jpg?v=1788757986","url":"https:\/\/voomisupply.com\/products\/kennametal-5591711-cpmt2152mf-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
