It carries an inscribed circle of 0.5000 inches and a thickness of 0.1563 inches (3.97 mm). With six cutting edges, a neutral hand orientation, a positive rake angle of 20 degrees, and a PM chip breaker geometry, this insert is engineered for high-feed face milling operations in demanding materials. The insert is held in place with a screw and fits the R300 and RA300 cutter series. Licensed machinists and tooling specialists handle installation and indexing.\u003c\/p\u003e\u003cp\u003eThis insert is designed for milling stainless steel, superalloys, and titanium — material groups M and S in ISO classification. Its rounded cutting edge style and positive rake geometry help manage heat and cutting forces when working tough, work-hardening materials in both roughing and semi-finishing passes. It conforms to both ANSI and ISO standards, with a catalog designation of R300-1340M-PM S40T and an insert size code of 1340. Typical applications include face milling and shoulder milling on CNC machining centers in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate in manufacturer grade S40T, rated for ISO material groups M40 and S35\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003eRound insert shape with 6 cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (20 degrees) with PM chip breaker reduces cutting forces on difficult materials\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 0.5000 inches with a corner radius of 0.2500 inches\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.1252 inches (3.18 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Sandvik Coromant R300 and RA300 cutter series, as specified by the manufacturer.

Use the appropriate Torx or hex key for the insert clamping screw; do not overtighten, as carbide inserts are brittle and can fracture under excessive clamp force. Inspect the pocket seat and clamping screw condition before seating a new insert. Confirm correct insert orientation and seating before resuming any cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: S40T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\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\u003eThickness\u003c\/strong\u003e: 0.1563 inches (3.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1252 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive, 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: M40, S35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding 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\u003eCutter Series Compatibility\u003c\/strong\u003e: R300, RA300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R300-1340M-PM S40T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R300-1340M-PM S40T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 x 1.54 x 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 5853449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734146122034,"sku":"5853449","price":270.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/424cbc67bbc29ed417170c0b2af78d87.jpg?v=1788761100","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5853449-round-milling-insert-s40t-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
