The insert carries the HT601CA manufacturer grade and features a 60-degree triangular geometry with a neutral hand orientation. Key specs include a 0.5 inch inscribed circle, a 0.0312 inch corner radius, and a 0.8660 inch insert length. The negative rake and zero-degree relief angle make this insert well-suited for hardened materials and high-temperature alloys where ceramic tooling outperforms carbide. Clamping and pin-style holding keeps it secure under interrupted and continuous cuts.\u003c\/p\u003e\n\u003cp\u003eThis insert fits standard TNGA toolholders used in precision turning applications across aerospace, automotive, and general machining environments. The TNGA432 size code and T00825 chip breaker designation are compatible with toolholder pockets specified for that insert size. It is appropriate for both roughing and finishing passes on hard ferrous materials where an uncoated ceramic grade provides thermal stability and edge retention. Licensed machinists and CNC operators performing precision turning work are the primary installers of this insert type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUncoated ceramic insert material for high-temperature and hardened-material cutting\u003c\/li\u003e\n  \u003cli\u003eTNGA insert style with neutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular shape provides three usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eHT601CA manufacturer grade engineered for demanding turning applications\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry with zero-degree clearance angle for stability under load\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for standard TNGA-style toolholders accepting a size 432 insert with a 0.5 inch inscribed circle and 3\/16 inch thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCeramic turning inserts should be seated and indexed by qualified CNC machinists or toolroom technicians following the toolholder manufacturer's clamping procedure. Power down and lock out the machine spindle before indexing or replacing any insert. Inspect the toolholder pocket and seating surfaces for chips or wear before installing a new insert. Ceramic inserts are brittle compared to carbide and should not be used for heavy interrupted cuts unless the grade is specifically rated for that application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNGA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT601CA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.8660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\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: 0.13 pounds\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: 8850566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":52104883241266,"sku":"8850566","price":313.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53d631bc2fab734470c675ad767e22ed.jpg?v=1790072342","url":"https:\/\/voomisupply.com\/products\/hertel-8850566-ceramic-turning-insert-tnga432t00825","provider":"Voomi Supply","version":"1.0","type":"link"}
