It carries a multilayer CVD coating  -  TiN, TiCN, and Al2O3  -  applied via MTCVD process, which builds wear resistance and thermal barrier properties in a single insert body. The 55-degree diamond (rhombic) shape provides a strong cutting geometry while the MF chip breaker geometry targets finishing and medium machining operations. Insert length is 11.63 mm with a 3\/8 inch inscribed circle and a 1\/64 inch corner radius. The screw-on holding method provides positive, repeatable seating in compatible toolholders. Installed by machinists and tool-room technicians in production and job-shop turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning, facing, boring, back turning, and back boring applications. Primary workpiece materials are steel (ISO P) and stainless steel (ISO M), with secondary capability on superalloys and titanium (ISO S). The KCM25 grade is characterized by high toughness on steel and moderate wear resistance with toughness on stainless steel. It is well-suited to both roughing passes at the shallower end of its depth-of-cut range and light finishing passes where surface finish consistency is critical. The neutral hand orientation makes it compatible with standard right-hand and left-hand toolholder configurations depending on setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating (TiN, TiCN, Al2O3) via MTCVD process for extended tool life on steel and stainless\u003c\/li\u003e\n  \u003cli\u003eDCMT 55-degree diamond shape with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry optimized for finishing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.050 inches (1.25 mm) suitable for light to moderate stock removal\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for edge stability and controlled engagement\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method for fast, repeatable index changes at the machine\u003c\/li\u003e\n  \u003cli\u003eNeutral hand  -  compatible with a wide range of standard DCMT toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on DCMT-style toolholders conforming to ANSI insert code DCMT3251 and ISO insert code DCMT11T304. Verify toolholder pocket geometry, clearance angle (7 degrees), and screw bore diameter (0.1732 inches) before installation.

Use the correct Torx or hex key for the insert screw and follow the toolholder manufacturer's recommended tightening sequence  -  do not overtighten, as this can crack the insert body or damage the pocket seat. Inspect the pocket seat and screw for wear or debris before indexing to the fresh cutting edge. This is a two-edge insert; once both edges are worn, the insert should be discarded rather than reground.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT3251\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT11T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3 (Multilayer CVD \/ MTCVD)\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\u003eInsert Length\u003c\/strong\u003e: 11.63 mm (0.9156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and 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\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.050 inches (1.25 mm)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 3760326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742204068146,"sku":"3760326","price":169.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf6c6e7f110a9ac74fb59e41eb6be9dd.jpg?v=1788835910","url":"https:\/\/voomisupply.com\/products\/kennametal-3760326-turning-insert-dcmt3251mf-kcm25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
