It carries grade BXA20 with a multilayer TiAlN PVD coating applied over a medium grain PCBN substrate. The insert features a 35-degree diamond shape, a 3\/8 inch inscribed circle, and a 0.016 inch corner radius. With a positive rake geometry and honed cutting edge, it is built for precision turning, facing, and boring operations where surface finish and tool life on hardened workpieces are the primary concerns. Installation is performed by licensed machinists and CNC toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning hard materials including hardened steels and similar ferrous alloys that fall within the H workpiece material classification. Its flat-top chipbreaker geometry and 7-degree relief angle make it appropriate for applications including turning, facing, boring, back turning, and back boring. The screw-holding method provides rigid clamping in compatible VCGW-style toolholders. The neutral hand orientation allows use in a broad range of toolholder configurations without handedness restrictions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN substrate with medium grain structure for hardened material cutting\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN PVD coating (grade BXA20) for thermal resistance and wear life\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (VCGW style) with 7-degree relief angle and positive rake\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge for improved edge integrity on hard workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMulti-tipped, 2-cutting-edge design maximizes insert utilization\u003c\/li\u003e\n  \u003cli\u003eScrew-mounted, neutral hand  -  compatible with turning, facing, boring, back turning, and back boring setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VCGW-style screw-clamp toolholders accepting a 3\/8 inch inscribed circle, 35-degree diamond insert.

Use the appropriate torque wrench and screw size specified by the toolholder manufacturer when seating the clamping screw. Inspect the toolholder pocket and seating surfaces for wear or debris before installing a new insert. Do not exceed the maximum depth of cut specification for this insert geometry.\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\u003eGrade\u003c\/strong\u003e: BXA20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VCGW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 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\u003eInsert Length\u003c\/strong\u003e: 1.308 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.173 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: 0.122 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Rake Geometry)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer PVD\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Medium Grain\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: 0.04 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: 6782056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972140171570,"sku":"6782056","price":128.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d338d9474592d39c65883b3de32f3d51.jpg?v=1789963330","url":"https:\/\/voomisupply.com\/products\/tungaloy-6782056-pcbn-turning-insert-vcgw331-bxa20","provider":"Voomi Supply","version":"1.0","type":"link"}
