Manufactured from an Alumina TiC ceramic substrate with a PVD-applied TiN coating, this insert delivers thermal stability and edge integrity at elevated cutting speeds where carbide grades lose effectiveness. The insert features a 55-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, and a 0.03 inches corner radius with a honed cutting edge. With four usable cutting edges and a flat-top chip breaker geometry, it is engineered for finishing operations. Licensed machinists and CNC turning specialists working on hardened steel and similar hard-material applications are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes on hard workpiece materials including hardened steels and hard alloys. The neutral hand orientation and negative rake geometry make it compatible with rigid, stable setups where vibration is minimized. Typical applications include turning, facing, boring, back turning, and back boring operations. The maximum depth of cut is 0.079 inches, confirming its role as a finishing insert rather than a roughing tool. It conforms to ANSI insert code DNGA432 and ISO insert code DNGA150408, making it a direct-fit option for toolholders dimensioned to those standards.\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 cutting performance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (ANSI code DNGA432 \/ ISO code DNGA150408)\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges with flat-top chip breaker geometry optimized for finishing\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces chipping on entry and exit\u003c\/li\u003e\n  \u003cli\u003eNeutral hand with negative rake and negative side clearance for secure clamping\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNGA-style toolholders conforming to ANSI and ISO dimensional standards for DNGA432 (ISO 150408) inserts with a 0.5-inch inscribed circle and 3\/16-inch insert thickness.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or removing the insert. Use the correct torque on the clamping screw per the toolholder manufacturer specification  -  do not over-torque ceramic inserts, as they are brittle and will crack under excessive clamping force. Inspect the insert pocket and seating surface for chips or contamination before each insert change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNGA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNGA150408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: LX11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic - Alumina TiC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (PVD process)\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: 1.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\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\u003eSide Clearance\u003c\/strong\u003e: Negative\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 Material\u003c\/strong\u003e: Hard Material (ISO code H)\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: 0.014 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: 6803163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":52062573003058,"sku":"6803163","price":333.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4275989d26153cac2271d16dc915dd48.jpg?v=1790042602","url":"https:\/\/voomisupply.com\/products\/tungaloy-6803163-ceramic-turning-insert-dnga432-lx11","provider":"Voomi Supply","version":"1.0","type":"link"}
