It carries the DNGA431T00625 geometry with an HP610CA manufacturer grade and a PVD-applied TiN coating over a ceramic substrate. The insert features a 55-degree diamond shape, neutral hand orientation, and a 1\/64 inch corner radius. These characteristics make it suited for high-speed finishing and semi-finishing passes on hardened ferrous materials where heat resistance and edge integrity are critical. The insert is installed by qualified machinists and toolroom technicians working with compatible DNGA-style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on hardened steels, cast irons, and similar materials where ceramic cutting tools outperform carbide in terms of heat resistance and cutting speed. The neutral hand orientation allows use in both left-hand and right-hand toolholder configurations. The DNGA insert style with clamp and pin holding method is commonly found in production turning environments, both job shop and high-volume manufacturing. The 55-degree included angle provides good nose strength for interrupted and continuous cut conditions at elevated surface speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic insert material with PVD TiN coating for extended tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with negative rake for increased edge strength\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with left-hand and right-hand toolholders\u003c\/li\u003e\n\u003cli\u003e1\/64 inch corner radius for finishing and semi-finishing surface quality\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in DNGA-style toolholders\u003c\/li\u003e\n\u003cli\u003eDNGA431T00625 geometry with HP610CA grade for high-speed hard-material turning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for DNGA-style toolholders accepting a 55-degree diamond insert with clamp and pin holding.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTurning inserts are seated and replaced by machinists following standard toolholder manufacturer procedures. Before changing an insert, ensure the machine spindle is fully stopped and all motion is locked out per shop LOTO procedures. Use the correct torque wrench and seating pin as specified by the toolholder manufacturer when securing the clamp. Inspect the insert pocket and seating surfaces for wear or debris before installing a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNGA\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\/Finish\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: Diamond (55 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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 8850555\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748104700210,"sku":"8850555","price":538.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1c704155255d83eb6a304881baec56d.jpg?v=1788889107","url":"https:\/\/voomisupply.com\/products\/hertel-8850555-turning-insert-dnga431t00625-hp610ca","provider":"Voomi Supply","version":"1.0","type":"link"}
