The insert features an 80-degree diamond (rhombic) shape with a 3\/8-inch inscribed circle, a 1\/32-inch corner radius, and a multilayer TiCN and Al2O3 coating applied via MTCVD and CVD processes. The KCM15B grade is engineered to balance moderate wear resistance with toughness, making it a reliable choice for interrupted and continuous cuts on steel and stainless steel. The MP chip breaker geometry supports roughing and medium machining applications across a broad range of feed and depth-of-cut conditions.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production turning of steel, stainless steel, superalloys, and titanium in both roughing and semi-finishing passes. The positive rake angle of 12 degrees and honed cutting edge reduce cutting forces and generate clean chip evacuation. The screw-on holding method provides rigid, repeatable seating in compatible CCMT-style toolholders. It delivers two cutting edges per insert, supporting cost-effective tooling management in high-volume shop environments. Typical users include machinists and CNC operators working in job shops, aerospace shops, and general manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond insert shape (CCMT) with positive side clearance and neutral hand for flexible tool orientation\u003c\/li\u003e\n\u003cli\u003eKCM15B grade with multilayer TiCN and Al2O3 MTCVD\/CVD coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eMP chip breaker supports roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (12 degrees) and honed cutting edge reduce cutting forces and extend edge life\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert for efficient tooling cost management\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method ensures secure, repeatable seating in CCMT toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-on replacement insert for CCMT-style toolholders conforming to ANSI insert code CCMT3252 and ISO insert code CCMT09T308.

Ensure the machine spindle is stopped and all axes are at a safe position before changing inserts. Use the appropriate Torx or hex key to seat the clamp screw to the toolholder manufacturer's specified torque range — do not overtighten, as this can crack the insert or damage the pocket. Inspect the insert pocket for chips or wear before seating a new insert, and confirm the cutting edge is indexed correctly before resuming cuts.\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 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\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3808 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1268 inches\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: 12 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD and CVD (Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MP (Roughing and Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003eMulti-Use Application\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package (minimum order quantity: 5)\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: 5640964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749676450098,"sku":"5640964","price":212.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c34800531ad42033dae24a7d1fb2b4f1_2c43bc25-dc5b-4572-b432-939c83522ad2.jpg?v=1788909077","url":"https:\/\/voomisupply.com\/products\/kennametal-5640964-turning-insert-ccmt3252mp-kcm15b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
