Built to the HT-VCMX insert style with a diamond (V) shape, it features a 0.25 inch inscribed circle, a 0.125 inch thickness, and a 0.0078 inch corner radius. The HT420CD grade is uncoated PCD, suited for high-speed machining of non-ferrous materials, composites, and abrasive workpiece materials where carbide tooling wears prematurely. Screw-held mounting provides secure clamping during interrupted or continuous turning passes. Machinists and CNC operators in production and job-shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is used in external and internal turning applications requiring tight tolerances and fine surface finishes. PCD grade HT420CD is particularly well suited for aluminum alloys, copper, brass, reinforced plastics, and carbon-fiber composites. The diamond shape with clearance code C and tolerance code M supports moderate to light depth-of-cut operations where dimensional accuracy is critical. The X chip breaker geometry assists with chip control in softer, ductile non-ferrous materials. It is sold individually, making it practical for low-volume replacement or tooling trials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolycrystalline Diamond (PCD) insert material for extended tool life in abrasive and non-ferrous cutting\u003c\/li\u003e\n\u003cli\u003eHT-VCMX insert style with diamond (V) shape and 35-degree included angle\u003c\/li\u003e\n\u003cli\u003e0.25 inch inscribed circle and 0.125 inch insert thickness\u003c\/li\u003e\n\u003cli\u003e0.0078 inch corner radius for fine finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting method for positive, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eX chip breaker geometry for improved chip control in ductile materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in HT-VCMX-style toolholders accepting a diamond-shaped insert with a 0.25 inch inscribed circle, clearance code C, tolerance code M, and screw-clamping retention. Consult your toolholder documentation to confirm insert style and size code 220.5 fitment before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert seats fully in the pocket before tightening. PCD inserts are extremely hard but brittle — avoid contact with ferrous workpieces and do not use on hardened steels, as impact or improper application can chip the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: HT-VCMX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V)\u003c\/li\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0078 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\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: X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 220.5\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\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: HTVCMX2205420CD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737384616242,"sku":"HTVCMX2205420CD","price":64.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67da8f9a1b14f9d78a490693b0a21546.jpg?v=1788787888","url":"https:\/\/voomisupply.com\/products\/hertel-htvcmx2205420cd-pcd-turning-insert-0-25in","provider":"Voomi Supply","version":"1.0","type":"link"}
