It carries ANSI insert code CNGA431 and ISO insert code CNGA120404, with an 80-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, and a 1\/64-inch (0.0157-inch) corner radius. The BX380 coarse-grain PCBN grade is left uncoated and features a flat-top chip breaker geometry with honed cutting edges. Licensed machinists and CNC turning specialists install this insert in clamp-and-pin style toolholders for high-precision finishing passes on hardened ferrous and wear-resistant workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing operations on hard materials, covering turning, facing, and boring applications. The negative rake, negative side clearance, and neutral hand orientation make it a versatile choice for stable, chatter-resistant cuts in hardened steels and similar hard-material families. With a maximum depth of cut of 0.0197 inches and two usable cutting edges, it is optimized for light, consistent finishing passes where surface finish and dimensional accuracy are critical. Typical installation environments include CNC turning centers and multi-axis lathes running hard-part turning programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN (polycrystalline cubic boron nitride) substrate, BX380 coarse-grain grade  -  engineered for hard-material finishing\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with flat-top chip breaker and honed cutting edge\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch (0.0157-inch) corner radius for tight-tolerance finishing passes\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; neutral hand for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method with 0.2030-inch hole diameter\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; multi-use for 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 clamp-and-pin toolholders accepting a 0.5-inch inscribed circle, 3\/16-inch thick, 80-degree diamond insert.

Ensure the machine spindle is stopped and the toolholder is fully secured in the turret before seating or replacing the insert. Verify clamp and pin engagement before resuming cuts. Do not exceed the rated maximum depth of cut of 0.0197 inches during finishing passes, as PCBN inserts are designed for light, precise cuts rather than heavy stock removal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Cubic Boron Nitride (PCBN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BX380\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Coarse Grain\u003c\/li\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 Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 Degree\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: 0.0157 inches (1\/64 inch)\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\u003eInsert Length\u003c\/strong\u003e: 0.5080 inches\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: 0.0197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 0.0910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\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\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\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\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2QP Mini-Tip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\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: 0.05 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: 6817919\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":52034241986866,"sku":"6817919","price":93.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2869598350407e5d0d36db35e7c8238b.jpg?v=1790022157","url":"https:\/\/voomisupply.com\/products\/tungaloy-6817919-pcbn-turning-insert-80-deg-diamond-bx380","provider":"Voomi Supply","version":"1.0","type":"link"}
