It carries the ANSI insert code CNGG431 and ISO code CNGG120404, with a diamond (rhombic) 80-degree insert shape that delivers sharp, defined cutting geometry. The chip breaker designation is 3F, optimized for controlled chip formation during finishing and semi-finishing passes. The corner radius measures 0.0156 inches (1\/64 inch), supporting tight-tolerance work on ferrous and non-ferrous materials. Manufacturer grade SP0819 identifies the specific carbide substrate and coating formulation. The part weighs approximately 0.04 pounds. Machinists, toolroom technicians, and production turning specialists are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning applications where a negative side clearance and clamp-plus-pin holding method are required. The C-shape 80-degree diamond geometry provides two usable cutting edges per insert and is commonly applied in finish turning, light profiling, and contour operations on lathes equipped with compatible CNGG-style toolholders. The 3F chip breaker geometry performs well in low-to-moderate depth-of-cut finishing scenarios where chip control and surface finish quality are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with manufacturer grade SP0819 substrate\u003c\/li\u003e\n\u003cli\u003eDiamond (rhombic) 80-degree insert shape (ANSI code C) for versatile turning geometry\u003c\/li\u003e\n\u003cli\u003e3F chip breaker for controlled chip formation in finishing operations\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0156 inches (1\/64 inch) for tight-tolerance surface finishing\u003c\/li\u003e\n\u003cli\u003eNegative side clearance with clamp and pin holding method for secure seating\u003c\/li\u003e\n\u003cli\u003eANSI size code 431, ISO size code 120404 for straightforward toolholder matching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for CNGG431 and CNGG120404 toolholder systems that accept a clamp-and-pin holding method with negative side clearance geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per OSHA lockout-tagout procedures. Seat the insert firmly in the pocket and verify clamp and pin engagement before resuming any cutting operation. Inspect the toolholder pocket for wear or debris before seating a new insert, as a damaged pocket will compromise cutting geometry and tool life. Follow the toolholder manufacturer torque guidelines for the clamping screw.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGG120404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNGG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 3F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: SP0819\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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: G\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: 0.04 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: 5661199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733384266034,"sku":"5661199","price":369.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83c62a7561296f2b84e5a17a1e9bfda6.jpg?v=1788754990","url":"https:\/\/voomisupply.com\/products\/kennametal-5661199-ccngg120404f-3f-turning-insert-sp0819","provider":"Voomi Supply","version":"1.0","type":"link"}
