Belonging to the T-Max P series, this insert features a 35-degree diamond shape (V) with a neutral hand orientation and a sharp cutting edge style. The ISO designation is VNGG 16 04 02-SGF H13A. With a corner radius of 0.20 mm (0.0078 inches) and an SGF chip breaker geometry, it is engineered for finishing and semi-finishing cuts where tight tolerances and surface finish quality are critical. The H13A uncoated carbide grade is specifically selected for heat-resistant and difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis insert is primarily intended for machining stainless steel (ISO material code M) and is also rated for secondary applications on superalloys and titanium (ISO material code S). It is well-suited to turning operations in aerospace, medical device, chemical processing, and oil and gas applications where these materials are common. A licensed machinist or CNC operator typically installs and indexes this insert on compatible toolholders in production or job-shop turning environments. The maximum depth of cut is 16.05 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVNGG insert style with 35-degree diamond shape and neutral hand for flexible toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eSGF chip breaker geometry optimized for sharp, controlled cutting on stainless steel and superalloys\u003c\/li\u003e\n\u003cli\u003eUncoated H13A solid carbide grade delivers consistent edge sharpness on heat-resistant workpiece materials\u003c\/li\u003e\n\u003cli\u003e0.20 mm corner radius supports finishing and close-tolerance semi-finishing operations\u003c\/li\u003e\n\u003cli\u003e4 available cutting edges per insert reduces per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method provides secure seating under interrupted or continuous cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with VNGG-style toolholders compatible with the T-Max P series platform.

Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert pocket seat for debris or damage before seating the new insert. Follow applicable shop safety procedures and machine tool manufacturer guidelines when handling carbide inserts, as edges are extremely sharp.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VNGG 16 04 02-SGF H13A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VNGG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (35 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: H13A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: SGF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0078 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.1500 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches decimal \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 16.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and Titanium (Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6851311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744556089650,"sku":"6851311","price":440.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/caea5627fbb38e81ea43d296d2fe08d2_8f42155c-67b8-461c-b5a0-4f95f24001de.jpg?v=1788858104","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6851311-vngg-turning-insert-h13a","provider":"Voomi Supply","version":"1.0","type":"link"}
