The insert features a PVD-applied titanium nitride (TiN) coating over an alumina TiC ceramic substrate. It carries an 80-degree diamond (rhombic) shape with a neutral hand orientation, a negative rake angle, and a honed cutting edge style. With four usable cutting edges and a flat-top chip breaker geometry, it delivers consistent edge performance during high-speed finishing passes. Licensed machinists and CNC toolroom technicians are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring applications on hard workpiece materials in both CNC and manual lathe setups. The CNGA style with negative side clearance and a clamp-and-pin holding method makes it appropriate for rigid toolholding systems. The flat-top chip breaker and honed edge are optimized for light finishing depths of cut, with a maximum depth of cut of 0.0787 inches. It conforms to both ANSI and ISO insert standards, with ANSI code CNGA431 and ISO code CNGA120404.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlumina TiC ceramic substrate with PVD TiN coating for hard-material finishing\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with 4 cutting edges\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0157 inches (1\/64 inch) for fine surface finish work\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry with honed cutting edge style\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance  -  compatible with clamp and pin toolholding\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGA-style insert toolholders that accept a 1\/2-inch inscribed circle, 3\/16-inch thick, 80-degree diamond insert with clamp-and-pin holding.

Before indexing or replacing inserts, confirm the machine spindle is fully stopped and the tool turret or holder is locked out per shop safety procedures. Seat the insert firmly against all locating surfaces in the pocket before tightening the clamp to avoid edge chipping. Inspect the pocket and pin for wear or debris prior to seating, as contamination can compromise insert location and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGA431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGA120404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic (Alumina TiC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: LX11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (PVD process)\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: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5080 inches\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: 0.0157 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (ISO H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6801825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51962597310770,"sku":"6801825","price":279.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a26f4e48f53669c91c8557685fa9d62.jpg?v=1789947794","url":"https:\/\/voomisupply.com\/products\/tungaloy-6801825-ceramic-turning-insert-cnga431-lx11","provider":"Voomi Supply","version":"1.0","type":"link"}
