The insert is made from solid carbide and features a multilayer CVD coating system consisting of TiN, TiCN, and Al2O3 applied via MT-CVD process. This coating stack delivers thermal resistance and wear resistance suited for continuous and interrupted cuts in steel. The insert measures 8.69 mm in length with a 0.5 inch inscribed circle and a 0.03125 inch corner radius. It carries a negative rake angle and a chamfered and honed cutting edge style, with six usable cutting edges per insert. Part of the KENLOC series, it is held in place by clamp or pin-type toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is rated primarily for steel workpiece materials (ISO material group P) and is suited for turning, facing, and boring operations in both roughing and semi-finishing passes. The RN chip breaker geometry controls chip flow effectively across a range of feed rates and depths of cut. The maximum depth of cut is 1.25 mm (0.0492 inch). It is used by machinists and CNC turning specialists in job shop and production environments where consistent tool life on steel is a priority. The ANSI and ISO standards compliance means it seats correctly in standard WNMG-style toolholders from multiple manufacturers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiN \/ TiCN \/ Al2O3 for wear and thermal resistance on steel\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eRN chip breaker geometry for controlled chip evacuation during turning and facing\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for edge strength and reduced micro-chipping\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards for WNMG-style insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement in WNMG432-style toolholders that accept clamp or pin holding methods. Conforms to ANSI and ISO standards for WNMG insert geometry, making it interchangeable in compliant toolholder blocks across the KENLOC series and equivalent third-party systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer  -  do not over-tighten the clamp screw, as this can fracture the insert. Inspect the toolholder pocket for debris or wear before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG432RN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP30\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: TiN \/ TiCN \/ Al2O3 (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MT-CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (80 degrees included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 8.69 mm (0.684 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code N)\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RN\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5 \/ C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: 3753664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740168519986,"sku":"3753664","price":185.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/631f63aa3da7189ac9f59d84cb511da3.jpg?v=1788823107","url":"https:\/\/voomisupply.com\/products\/kennametal-3753664-wnmg432rn-kcp30-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
