Built to the CNMA insert standard, it features a 1\/2 inch inscribed circle, a 3\/16 inch insert thickness, and a 1\/32 inch corner radius. The HT420CD grade uses an uncoated PCD substrate, which delivers exceptional hardness and wear resistance for machining non-ferrous metals, composites, and abrasive materials. Machinists and toolroom technicians working with aluminum alloys, copper, carbon fiber, and similar workpiece materials specify this insert for high-speed finishing and semi-finishing passes where tool life and surface finish consistency are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for light to moderate turning applications in production and job-shop environments. The diamond insert shape (Shape Code C) with a neutral clearance angle (Clearance Code N) and medium tolerance (Tolerance Code M) makes it a practical choice for general turning on Swiss-type machines, gang-tooling setups, and conventional CNC lathes. The chip breaker designation A and insert size code 432 align with common CNMA toolholder systems. It is intended for use by machinists and CNC operators maintaining tight dimensional tolerances on non-ferrous and composite parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolycrystalline Diamond (PCD) insert material for superior hardness and abrasion resistance on non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves sharp cutting edge geometry without coating buildup\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch inscribed circle (12.70 mm) fits standard CNMA toolholder pockets\u003c\/li\u003e\n  \u003cli\u003e1\/32 inch (0.0313 inch) corner radius balances edge strength with surface finish performance\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method provides positive insert retention under interrupted or continuous cuts\u003c\/li\u003e\n  \u003cli\u003eMaterial Grade C2 suitable for non-ferrous and non-metallic workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for CNMA-style toolholders accepting a size 432 insert with clamp and pin holding.

Always index or replace inserts with the machine spindle stopped and all axes at a safe home position. Use the correct torque driver or clamp screw for the toolholder manufacturer's specified clamping torque to avoid cracking the PCD substrate. PCD inserts are brittle against impact — avoid interrupted cuts on ferrous or hardened materials, as these applications can fracture the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Diamond (PCD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT420CD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inch \/ 12.70 mm)\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\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inch\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\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\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HTCNMA432420CD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728863822130,"sku":"HTCNMA432420CD","price":70.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb5962afeeb329f65efb37b1ac26e620.jpg?v=1788697079","url":"https:\/\/voomisupply.com\/products\/hertel-htcnma432420cd-pcd-turning-insert-1-2-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
