The insert is manufactured from carbide and carries a PVD-applied TiCN plus TiN coating that delivers high wear resistance with moderate toughness. It features an 80-degree diamond (rhombic) shape with a neutral hand orientation and a negative side clearance, making it compatible with standard CNMG-style toolholders. With four usable cutting edges per insert, it offers efficient cost-per-edge performance in high-volume turning applications. The T-Max P series designation places it within a well-established platform for external turning and profiling work. Licensed machinists and CNC lathe operators are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing passes on steel workpieces (ISO material code P) as the primary application, with secondary capability on stainless steel (M) and cast iron (K). The PF chip breaker geometry is optimized for finishing cuts where controlled chip formation and a fine surface finish are the primary objectives. It is commonly used in both CNC turning centers and manual engine lathes equipped with a compatible CNMG negative-rake toolholder. The T-Max P series is a general-purpose external turning platform appropriate for both job-shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape provides a strong cutting edge with versatile approach angle options\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiCN plus TiN coating delivers high wear resistance suited for steel finishing applications\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry targets finishing operations with controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert reduce tooling cost per edge in production turning\u003c\/li\u003e\n\u003cli\u003eNegative side clearance with clamp-and-pin holding method ensures rigid, repeatable seating in the toolholder\u003c\/li\u003e\n\u003cli\u003eGrade 1525 characteristics balance wear resistance and toughness for steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style negative-rake turning toolholders.

Seat the insert firmly into the toolholder pocket before tightening the clamp or pin to ensure proper contact with the locating surfaces. Inspect the insert pocket and clamping components for chips or damage before each index. Do not attempt to regrind or modify the cutting edges on this coated carbide insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: CNMG 12 04 04-PF 1525\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1525\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: 0.4920 inches (12.50 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: 0.0156 inches (0.40 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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 5724728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51736325259570,"sku":"5724728","price":283.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4056847be83bcdc629fe5c81f2fb36d8.jpg?v=1788777230","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5724728-cnmg431-pf-1525-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
