This single-sided insert carries a three-layer CVD coating — TiCN, Al2O3, and TiN — applied to a solid carbide substrate in manufacturer grade 4340. It measures 0.5 inches in inscribed circle diameter and 0.1563 inches thick, with a 0.25-inch corner radius and a positive rake angle of 20 degrees. The insert is held in place by a screw and delivers 6 cutting edges per insert, making it a cost-effective option for high-volume material removal on steel, stainless steel, and cast iron. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling operations on steel, stainless steel, and cast iron workpieces, covering ISO material grades P40, M40, and K40. Its neutral hand orientation allows use in standard R300-series toolholders without regard to spindle direction preference. The PM chip breaker geometry supports both roughing and semi-finishing cuts. Maximum depth of cut is 3.18 mm (0.1252 inches). Typical applications include face milling, shoulder milling, and ramping on CNC machining centers in production shop and job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound insert shape (360-degree included angle) with 6 usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eThree-layer CVD coating: TiCN, Al2O3, TiN for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 20 degrees reduces cutting forces on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry supports roughing through semi-finishing operations\u003c\/li\u003e\n\u003cli\u003eNeutral insert hand for flexible toolholder compatibility in R300-series cutters\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method for positive insert retention under high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SANDVIK COROMANT RA300-series cutter bodies.

Use the appropriate Torx or hex key for the clamping screw as specified by the toolholder manufacturer — do not overtighten or use impact tools on insert screws. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Index to the next cutting edge or replace the insert when surface finish or chip formation indicates edge wear.\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4340\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P40, M40, K40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: RA300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R300-1340M-PM 4340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R300-1340M-PM 4340\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: 0.011 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: 7564589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750618792242,"sku":"7564589","price":220.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c172fba5d733542649f8044d857be61f_3be27448-67b3-4f75-91a3-6adbbf407687.jpg?v=1788917452","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7564589-round-carbide-milling-insert-r300","provider":"Voomi Supply","version":"1.0","type":"link"}
