The insert is manufactured from solid carbide with a multilayer MTCVD-applied TiCN plus Al2O3 coating for wear resistance and thermal stability during interrupted and continuous cuts. The triangular 60-degree insert geometry provides six usable cutting edges per insert, maximizing tool life in high-volume turning applications. With a 3\/8-inch inscribed circle, a 3\/16-inch thickness, and a 1\/64-inch corner radius, this insert is engineered for roughing and medium machining operations on steel and stainless steel workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring operations on steel (ISO P) and stainless steel (ISO M) workpieces, with grade characteristics offering moderate-to-high wear resistance combined with toughness. The MP chip breaker geometry is optimized for roughing and medium machining passes where chip control is critical. The neutral hand orientation and negative rake angle suit it for rigid setups on CNC lathes and turning centers in production environments. Licensed machinists and tooling technicians working with ferrous alloys, stainless grades, and superalloys or titanium will find the KCM15B grade appropriate for demanding material removal rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSix usable cutting edges per insert — reduces per-edge tooling cost in high-volume turning\u003c\/li\u003e\n  \u003cli\u003eMultilayer MTCVD TiCN plus Al2O3 CVD coating — resists wear and thermal deformation\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker geometry — effective for roughing and medium machining with reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle with chamfered and honed cutting edge — edge strength for interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eCompatible with KENLOC clamp and pin insert-holding systems\u003c\/li\u003e\n  \u003cli\u003eANSI and ISO standardized geometry (ANSI: TNMG331, ISO: TNMG160404) for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConforms to ANSI insert code TNMG331 and ISO insert code TNMG160404, fitting KENLOC-series toolholders and other clamp- or pin-style toolholders designed for TNMG geometry inserts.

Use the correct KENLOC clamp or pin-style toolholder specified for TNMG geometry to ensure proper seating and clamping force. Inspect the insert pocket and seating surfaces for chips or debris before indexing to a fresh cutting edge. Follow the toolholder manufacturer torque specifications for the clamping screw — do not over-tighten.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG160404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMG331MP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM15B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\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 plus Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD (CVD classification)\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 6 degrees\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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.50 mm (0.6496 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inch (3.81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2163 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0156 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: 5641110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51751803846962,"sku":"5641110","price":150.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60aaabde4199abc90794f297853cd269_9e34f9ff-15f2-4a59-88f9-32b62e7a5b93.jpg?v=1788924321","url":"https:\/\/voomisupply.com\/products\/kennametal-5641110-tnmg331mp-turning-insert-kcm15b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
