The insert features a 55-degree diamond shape with a neutral rake and a 0-degree relief angle (Clearance Code N), making it engineered for high-hardness and cast iron turning applications. It measures 15.50 mm (0.6102 inches) in length with an inscribed circle of 0.5000 inches and an insert thickness of 0.1874 inches. A 1\/32-inch corner radius (0.0315 inches) is built in to balance edge strength and surface finish. The IB50 grade CBN composition is designed to handle interrupted and continuous cuts in hard and abrasive materials. Licensed machinists and CNC turning specialists are the primary installers of this tooling insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing and semi-finishing operations on cast iron and hard materials, consistent with Primary Workpiece Material Codes H and K under ISO 13399 classification. The DNMA 432T geometry fits standard DNMA-compatible toolholders used on CNC lathes and turning centers in both production shop and job shop environments. The T chip breaker designation and neutral rake contribute to stable chip control at the cutting edge. Maximum depth of cut is rated at 0.50 mm (0.0197 inches), placing this insert firmly in the finishing cut range for demanding material groups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCubic Boron Nitride (CBN) insert material rated for hard materials and cast iron (Material Codes H and K)\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (DNMA style, Insert Shape Code D) for tight clearance and profiling capability\u003c\/li\u003e\n\u003cli\u003eIB50 manufacturer grade with bright, uncoated finish for consistent edge geometry out of the box\u003c\/li\u003e\n\u003cli\u003e0.0315-inch corner radius balances cutting-edge strength with surface finish requirements\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in compatible DNMA toolholders\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards for seamless integration into CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for DNMA 432-style toolholder pockets accepting a 0.5000-inch inscribed circle insert with clamp and pin retention.

Power down and lock out the CNC machine spindle before changing inserts. Inspect the insert pocket and locating pin for wear or debris before seating the new insert to ensure proper contact and prevent premature edge failure. CBN inserts are brittle relative to carbide; avoid impact or dropping during handling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IB50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cubic Boron Nitride (CBN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\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: 0.1874 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: T\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.50 mm (0.0197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material (Codes H and K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 5700436\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747340976434,"sku":"5700436","price":459.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/001fabbf54f25ee3731e242be880818f.jpg?v=1788878840","url":"https:\/\/voomisupply.com\/products\/iscar-5700436-cbn-turning-insert-dnma-432t-ib50","provider":"Voomi Supply","version":"1.0","type":"link"}
