This indexable insert is manufactured from carbide substrate and coated with a CVD-applied multilayer stack of TiCN, Al2O3, and TiN for wear resistance and thermal protection. The insert features a 55-degree diamond shape, neutral hand orientation, and an MF chip breaker geometry suited for medium to light finishing passes. With four cutting edges per insert, it delivers a low cost-per-edge in production environments. The 0.5789-inch insert length and 0.5-inch inscribed circle correspond to the ISO DNMG 15 04 08 designation.\u003c\/p\u003e\u003cp\u003eThe 5731314 is engineered primarily for cutting stainless steel (ISO material group M), where the MF chip breaker geometry and CVD multilayer coating work together to manage built-up edge and heat at the cutting zone. Typical applications include shaft turning, facing, and contour work on austenitic and duplex stainless grades in both job-shop and production environments. The T-Max P series platform this insert belongs to is designed for secure clamping in standard negative-rake toolholders used by machinists and CNC operators across general and precision turning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for extended tool life in stainless steel cutting\u003c\/li\u003e\n\u003cli\u003eDNMG 55-degree diamond shape with neutral hand orientation for versatile turning setups\u003c\/li\u003e\n\u003cli\u003eMF chip breaker geometry optimized for medium-light finishing cuts\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert reduces per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method for rigid, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eISO code DNMG 15 04 08-MF 2025 for direct cross-reference and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style negative-rake toolholders that accept clamp and pin insert retention.

Always power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket locating surfaces before tightening the clamp screw; incomplete seating causes premature edge failure and poor surface finish. Inspect the insert pocket and clamp for chips or debris before each insert change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 15 04 08-MF 2025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-degree Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: 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: MF\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: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5789 inches (14.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (0.79 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Group M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5731314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51742881612082,"sku":"5731314","price":386.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c66652ec499836f0fbf73603904f452d_cc4cbd64-0da6-4265-b7fb-0ab19a2f39a0.jpg?v=1788840184","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5731314-dnmg432-mf-2025-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
