Manufactured under the Isoturn series, this insert carries the ANSI code DNGA432 and ISO code DNGA150408. It features a 55-degree diamond (rhombic) shape with a negative side clearance and a T-style chip breaker optimized for finishing operations. The IN22 ceramic grade delivers high wear resistance, making it well-suited for machining cast iron and hardened materials where tool longevity under abrasive cutting conditions is required. Licensed trades machinists and tooling technicians specify this insert for high-speed finishing passes.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning centers and lathes performing finishing operations on cast iron (ISO material group K) and hardened materials (ISO material group H). The T chip breaker geometry controls chip flow during light-depth finishing cuts. Typical install scenarios include production turning environments where surface finish consistency and tool life predictability are priorities. The insert seats in toolholders using clamp or pin holding methods compatible with the DNGA insert style.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic uncoated IN22 grade with high wear resistance for cast iron and hardened material finishing\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (rhombic) insert shape with negative clearance for stable seating\u003c\/li\u003e\n\u003cli\u003eT chip breaker geometry engineered for finishing operations\u003c\/li\u003e\n\u003cli\u003eClamp and pin compatible holding method for secure insert retention\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.138 inches supports controlled finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-specification turning insert for DNGA-style toolholders accepting a 1\/2-inch inscribed circle, 55-degree diamond insert with negative clearance, compatible with clamp or pin holding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert replacement and seating should be performed by a qualified machinist or tooling technician with the machine powered down and all axes locked. Inspect the toolholder pocket and seating surfaces for debris or wear before installing the new insert. Follow the toolholder manufacturer's clamping torque guidelines for DNGA-style clamp or pin systems. Ceramic inserts are brittle and should not be used for interrupted cuts or applications outside the specified finishing parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNGA432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNGA150408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IN22\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: Bright\/Uncoated\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: 15.50 mm (0.6102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.138 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: T (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (K), Hardened Materials (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5791797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51742190829874,"sku":"5791797","price":261.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/276b60d7364c67363dc7de582a71efd8.jpg?v=1788835899","url":"https:\/\/voomisupply.com\/products\/iscar-5791797-turning-insert-dnga-432t-in22-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
