The insert features an 80-degree diamond (rhombic) shape, a negative rake angle, a honed cutting edge, and a flat-top chip breaker. With a 0.5 inch inscribed circle, a 0.0315 inch corner radius, and an insert thickness of 0.1875 inches, this uncoated PCBN insert delivers high wear resistance in demanding turning, facing, and boring applications. It is installed by machinists and CNC turning specialists in production environments where tool life and surface finish consistency are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes on cast iron (ISO material group K) and hardened materials (ISO material group H) where high wear resistance is required. Its 2QP Mini-Tip series design supports multi-use application across turning, facing, and boring operations. The maximum depth of cut is 0.0197 inches, making it optimized for light, precise finishing cuts rather than heavy roughing. The neutral hand orientation allows flexible use in standard CNGA-style toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN (polycrystalline cubic boron nitride) insert material for high wear resistance in hard and abrasive workpieces\u003c\/li\u003e\n  \u003cli\u003eBX930 manufacturer grade optimized for cast iron and hardened material finishing\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape, ANSI\/ISO standard geometry CNGA432 \/ CNGA120408\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish with honed cutting edge for consistent, repeatable surface quality\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; compatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMulti-use capable for turning, facing, and boring in a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGA-style toolholders accepting a 432 size insert.

Ensure the machine spindle is fully stopped and all power is isolated before indexing or replacing the insert. Seat the insert firmly against the toolholder pocket using the appropriate clamp or pin mechanism per the toolholder manufacturer's instructions. Verify the cutting edge is secure and the insert is properly indexed before resuming machine operation.\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: BX930\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGA120408\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\u003eInsert Length\u003c\/strong\u003e: 0.508 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 0.087 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\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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: Cast Iron (K), Hardened Materials (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2QP Mini-Tip\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: 0.01 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: 6817929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972183490866,"sku":"6817929","price":90.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95d280906a1df858e7093f092cb524a3.jpg?v=1789963888","url":"https:\/\/voomisupply.com\/products\/tungaloy-6817929-pcbn-turning-insert-cnga432-bx930","provider":"Voomi Supply","version":"1.0","type":"link"}
