Manufactured in the HT-VNMA insert style with a diamond (V) shape, this insert features a 3\/8 inch inscribed circle and a 1\/32 inch corner radius. The HT420CD grade is uncoated, and the insert material is Polycrystalline Diamond, making it well suited for high-speed finishing of non-ferrous metals, composites, and abrasive materials. At 3\/16 inch thick with a material grade of C2, it is built for consistent edge retention and dimensional accuracy in turning applications. Licensed machinists and CNC operators install this insert type in standard toolholders on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in turning applications where tight tolerances and fine surface finishes are required. The HT-VNMA style fits compatible VNMA-style toolholders commonly used in external and internal turning operations on CNC lathes. Typical applications include finish turning of aluminum alloys, copper, graphite, and other non-ferrous or abrasive workpiece materials. The uncoated PCD construction performs in high-surface-speed conditions where coated carbide would wear prematurely. This insert is sold individually with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolycrystalline Diamond (PCD) insert material for high wear resistance in non-ferrous and abrasive applications\u003c\/li\u003e\n\u003cli\u003eHT420CD uncoated grade with C2 material classification\u003c\/li\u003e\n\u003cli\u003eDiamond insert shape (V) with HT-VNMA style for precise external and internal turning\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle (0.3750 inch) for accurate toolholder fitment\u003c\/li\u003e\n\u003cli\u003e1\/32 inch corner radius (0.0313 inch) for fine-finish turning operations\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for VNMA-style turning toolholders accepting a diamond (V) shape insert with a 3\/8 inch inscribed circle and clamp or pin holding method.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the machine is in a locked-out, de-energized state before changing inserts. Use the appropriate torque wrench and clamp hardware specified for the toolholder to secure the insert without cracking the PCD substrate. Verify insert seating and edge orientation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Diamond (PCD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: HT-VNMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (Shape Code V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT420CD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inch\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 332\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HTVNMA332420CD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736407179570,"sku":"HTVNMA332420CD","price":78.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adc203bb1b3f6a149e6a69bc25817503.jpg?v=1788777790","url":"https:\/\/voomisupply.com\/products\/hertel-htvnma332420cd-pcd-turning-insert-3-8-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
