It carries the ANSI insert code CNMG432 and ISO insert code CNMG120408, featuring an 80-degree diamond (rhombic) shape with a negative side clearance geometry. The inscribed circle measures 0.5 inches, the corner radius is 0.031 inches, and the insert thickness is 0.187 inches. Grade NL300 carbide construction and a 3J chip breaker geometry make this insert suited for controlled-chip turning operations. Licensed machinists and CNC operators install this insert as part of a standard clamp-and-pin toolholding setup.\u003c\/p\u003e\u003cp\u003eThis insert is applied in turning operations on CNC lathes and manual turning centers where an 80-degree diamond insert is required. The CNMG style with negative rake geometry is commonly used for external and internal turning of ferrous and non-ferrous metals. The 3J chip breaker is engineered for medium to finishing depth-of-cut ranges, making it appropriate for tight-tolerance work on production and job-shop floors alike. The Tolerance Code M and Clearance Code N define the dimensional fit class for this insert within standard CNMG-compatible toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI insert code CNMG432, ISO insert code CNMG120408 for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape provides a strong cutting edge geometry\u003c\/li\u003e\n\u003cli\u003eNegative side clearance with 0-degree relief angle suits heavy and interrupted cuts\u003c\/li\u003e\n\u003cli\u003e3J chip breaker geometry supports medium to finishing turning passes\u003c\/li\u003e\n\u003cli\u003eNL300 solid carbide grade for wear resistance in metal turning\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible with standard CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for use in standard CNMG432-compatible clamp-and-pin toolholders.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and pocket stop before tightening the clamp; uneven seating can cause premature edge failure or chatter. Refer to the toolholder manufacturer torque specification for the clamp screw  -  do not over-tighten.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120408\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.187 inches (3\/16 inches)\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: NL300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 3J\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\u003eClearance Code\u003c\/strong\u003e: N\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 5653377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744470434098,"sku":"5653377","price":337.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3432bcf7f38f2a956162ac0dc051cd62.jpg?v=1788856951","url":"https:\/\/voomisupply.com\/products\/kennametal-5653377-cnmg432a-3j-turning-insert-0-5in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
