Part of the KENLOC series, this insert features a 60-degree triangular shape, a neutral hand orientation, and a negative rake angle of 6 degrees. The inscribed circle measures 0.375 inches, insert length is 0.6496 inches (16.5 mm), and the corner radius is 0.0313 inches (1\/32 inch). With 6 cutting edges and a chamfered-and-honed cutting edge style, it is designed for productive use in high-volume turning, facing, and boring operations. Licensed machinists and CNC operators working in job shops and production facilities are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for cutting steel, stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material codes P, M, and S. The MP chip breaker geometry is suited for medium-pass turning applications where controlled chip formation and surface finish consistency are required. The MTCVD multilayer coating provides thermal resistance and wear performance across a range of cutting parameters. It is appropriate for both roughing and semi-finishing passes in general turning and facing operations on CNC lathes and turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCM15B grade with multilayer TiCN and Al2O3 CVD coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eTNMG332MP geometry: 60-degree triangle, neutral hand, negative rake\u003c\/li\u003e\n\u003cli\u003e6 usable cutting edges per insert, maximizing value per unit\u003c\/li\u003e\n\u003cli\u003eMP chip breaker optimized for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for edge stability\u003c\/li\u003e\n\u003cli\u003eCompatible with KENLOC clamp-and-pin insert holding systems\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO code TNMG160408MP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-style toolholders that accept TNMG-geometry inserts with clamp and pin holding methods.

Ensure the machine spindle is stopped and the turret is fully indexed and locked before changing inserts. Seat the insert fully against the pocket locating surfaces before engaging the clamp or pin to avoid micro-movement under cutting loads. Follow the toolholder manufacturer's clamping torque guidelines and verify insert seating visually before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG160408MP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMG332MP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\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\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\u003eChip Breaker\u003c\/strong\u003e: MP\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: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches (16.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2163 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P, M, S\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\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 5640490\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730013258034,"sku":"5640490","price":150.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60aaabde4199abc90794f297853cd269.jpg?v=1788710192","url":"https:\/\/voomisupply.com\/products\/kennametal-5640490-tnmg332mp-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
