This round-profile insert carries a Manufacturer Grade 650 ceramic substrate with a PVD-applied Titanium Nitride (TiN) coating for extended tool life. It features a negative land cutting edge style, a neutral hand orientation, and delivers 8 usable cutting edges per insert. With a 1\/2 inch (0.5000 inch) inscribed circle and 3\/16 inch (0.1875 inch) thickness, this insert is suited for production turning operations where ceramic grades are specified. Machinists and CNC programmers working in job shops or production environments will specify this insert for demanding turning passes.\u003c\/p\u003e\n\u003cp\u003eThis insert targets primary applications in cast iron turning, with secondary suitability for superalloys and titanium. The T-Max P series designation indicates compatibility with Sandvik Coromant T-Max P toolholders accepting RNGA-style round inserts. Typical use cases include roughing and semi-finishing passes on cast iron components where higher cutting speeds and ceramic grades outperform carbide. The insert is sold individually (quantity of 1 per package) and intended for professional CNC lathe and turning center setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 650 ceramic insert with PVD Titanium Nitride coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRound insert shape (RNGA style) providing 8 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eNegative land cutting edge style for strength on hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard RNGA toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for secure seating under high cutting forces\u003c\/li\u003e\n  \u003cli\u003ePrimary workpiece material: Cast Iron (ISO K); secondary: Superalloy and Titanium (ISO S)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Sandvik Coromant T-Max P series toolholders accepting RNGA-style round inserts with a 1\/2 inch inscribed circle. ISO code RNGA120400T01020650 identifies the full insert specification for cross-referencing with compatible clamping systems. Confirm toolholder pocket geometry and clamping style before substituting inserts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert seating and indexing should be performed by a qualified machinist or toolsetter with the machine in a locked-out, zero-energy state. Ensure the insert pocket, clamp, and pin are clean and free of debris before seating the insert, as contamination can cause improper seating and premature edge failure. Torque clamp screws per the toolholder manufacturer specification — do not rely on feel alone. Ceramic inserts are brittle compared to carbide; avoid interrupted cuts or conditions outside the grade recommendations without engineering review.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNGA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 650\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Negative Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inch \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch \/ 4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2032 inch (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\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\u003eChip Breaker\u003c\/strong\u003e: A\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 (ISO K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium (ISO S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RNGA120400T01020650\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5741157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750681346354,"sku":"5741157","price":31.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdf8671f670be98ac6f651d9fe34a644.jpg?v=1788918326","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5741157-ceramic-turning-insert-rnga","provider":"Voomi Supply","version":"1.0","type":"link"}
