Manufactured to the 490 series platform, it carries an S30T grade designation and a TiAlN coating applied via PVD process for enhanced wear resistance and thermal stability. The insert features a square shape with a positive rake angle of 32 degrees and four usable cutting edges, making it a cost-effective choice for high-productivity milling. The inscribed circle measures 8.50 mm and the insert is 3.30 mm thick. Licensed machinists and CNC tool-room technicians will recognize this as the 490R-08T308E-ML S30T geometry, conforming to both ANSI and ISO standards.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling stainless steel, superalloys, and titanium — ISO material groups M and S. The ML chip breaker geometry and corner-rounded cutting edge style are optimized for finishing and semi-finishing passes at moderate to aggressive feed rates. A maximum depth of cut of 5.50 mm supports versatile application in both roughing and finishing contexts on vertical and horizontal machining centers running 490-series cutter bodies. Right-hand cutting orientation applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eS30T solid carbide grade with PVD TiAlN coating for wear resistance in stainless steel and superalloy machining\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges on a single-sided square insert maximize tool economy\u003c\/li\u003e\n  \u003cli\u003eML chip breaker geometry supports controlled chip evacuation in gummy or stringy materials\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 32 degrees reduces cutting forces on difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.80 mm (1\/32 inch) with corner-rounded edge style for smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 5.50 mm accommodates both semi-finish and light roughing operations\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting for secure, repeatable insert indexing in 490-series cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Sandvik Coromant 490-series milling cutter bodies.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key specified by the cutter body manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the insert. Inspect the insert pocket seating surface and clamping screw for wear or debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 490\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: S30T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 8.50 mm (0.3346 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.30 mm (0.1299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 5.50 mm (0.2165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 32 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ML\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M25, S25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 08T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 490R-08T308E-ML S30T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 490R-08T308E-ML S30T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 5853557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732046250290,"sku":"5853557","price":554.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3a816addd3215a611d4715be0d1154f_2697da24-0e44-4c9c-803d-89246877f662.jpg?v=1788738624","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5853557-square-milling-insert-s30t-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
