Manufactured to grade HP610CA with a PVD-applied TiN coating, this insert offers improved wear resistance and edge integrity under demanding cutting conditions. The triangular insert geometry features a 60-degree included angle, a neutral hand orientation, and a negative rake configuration. The inscribed circle measures 0.375 inches, insert length is 0.63 inches, and thickness is 0.1875 inches. Machinists and tool-room technicians working with hard or abrasive materials will find this insert well-suited to finishing and semi-finishing passes.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on lathes where ceramic tooling grades are specified for the workpiece material. The TNGA style with neutral hand is commonly used in both climb and conventional turning setups. The 0.0312-inch corner radius supports fine surface finishes while maintaining edge strength. It is held in place by clamp and pin holding methods, compatible with standard TNGA toolholders. Packaging quantity is 1 insert per package with a minimum order quantity of 10 units, making it a standard shop-supply item for tooling inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHP610CA ceramic grade with PVD TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eTNGA332 style, triangular shape with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eNegative rake and neutral hand orientation for versatile turning setups\u003c\/li\u003e\n\u003cli\u003e0.0312-inch corner radius for fine surface finish capability\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure, repeatable seating in toolholder\u003c\/li\u003e\n\u003cli\u003eChip breaker style A for controlled chip formation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TNGA332T00625 style inserts in standard TNGA-compatible toolholders.

Always disengage the machine spindle and lock out the lathe before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Ceramic inserts are brittle and should not be subjected to interrupted cuts or heavy shock loading unless the grade is specifically rated for such conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNGA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle Code\u003c\/strong\u003e: TNGA332-T00625\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP610CA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.63 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\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\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\u003eWeight\u003c\/strong\u003e: 0.08 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: 8850564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51972045504818,"sku":"8850564","price":251.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5264d57a33821f0748aa0f89198e675.jpg?v=1789961826","url":"https:\/\/voomisupply.com\/products\/hertel-8850564-tnga332t00625-ceramic-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
