It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability in demanding cutting applications. The insert carries an 80-degree diamond shape with a neutral hand orientation, a 1\/2-inch inscribed circle, and a 1\/32-inch corner radius. With four cutting edges per insert and a KR chip breaker, it is suited for productive turning operations on cast iron workpieces. Licensed machinists and CNC turning specialists install this insert in compatible CNMA-style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for turning cast iron components in both roughing and finishing contexts where a stable, clamped insert is required. The KR chip breaker geometry promotes controlled chip flow during cast iron cutting. The CNMA 432 designation indicates a 4.76 mm insert thickness, 12.70 mm inscribed circle, and 12.10 mm insert length. Insert holding is accomplished via clamp and pin methods. The ISO code for this insert is CNMA 12 04 08-KR 3210, and the manufacturer grade is 3210.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eKR chip breaker designed for cast iron turning applications\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eClearance code N, tolerance code M per ISO insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe SANDVIK COROMANT 5725031 is compatible with CNMA-style toolholders designed for the T-Max P series.

Before indexing or replacing the insert, power down the machine and confirm the spindle is fully stopped. Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamp screw. Do not exceed the toolholder manufacturer's recommended clamping torque, and inspect the insert seat and clamp for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches \/ 0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4762 inches (12.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMA 12 04 08-KR 3210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5725031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51740261024050,"sku":"5725031","price":304.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bac9eb9c0f9d71eb9c8400e63c15309_5a671dd7-c865-4fe9-9fd1-42e1003c5cbe.jpg?v=1788823834","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5725031-turning-insert-cnma432-kr-3210","provider":"Voomi Supply","version":"1.0","type":"link"}
