Manufactured in a pentagon (5-sided) shape with a positive rake geometry and corner-rounded cutting edge style, this insert delivers controlled chip formation across a range of workpiece materials. It carries a CVD tri-layer coating of TiCN, Al2O3, and TiN, which provides thermal resistance, wear protection, and oxidation resistance during high-speed or interrupted cutting. With five usable cutting edges per insert and a screw-holding method, it offers efficient tool life management for production environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for face milling, shoulder milling, and general-purpose milling of steel, stainless steel, and cast iron in both roughing and semi-finishing passes. It is classified under manufacturer grade 4340 with material grade designations P40, M40, and K40, making it applicable across ISO material groups P, M, and K. Typical installation is performed by machinists and tooling technicians in CNC machining centers and manual milling setups. The insert fits Series 419 cutter bodies and uses a PM chip breaker geometry optimized for the stated workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePentagon insert shape with 5 cutting edges for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eCVD tri-layer coating: TiCN, Al2O3, and TiN for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003ePositive rake angle with PM chip breaker geometry for controlled chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation with screw-type insert holding method\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 2.00 mm (0.0787 inches)\u003c\/li\u003e\n\u003cli\u003eCompatible with ISO and ANSI standards; ANSI\/ISO code 419R-1405M-PM 4340\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series 419 indexable milling cutter bodies.

Power down and lock out all spindle drives before indexing or replacing inserts. Inspect the insert pocket seat for chips or debris before seating the new insert, as contamination causes premature edge failure. Insert handling should be done with care; solid carbide edges are brittle and can chip if dropped or impacted against hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P40, M40, K40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 419\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Pentagon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5315 inches (13.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2154 inches (5.47 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0787 inches (2.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1405\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive, 0 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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: 419\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\u003eANSI Code\u003c\/strong\u003e: 419R-1405M-PM 4340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 419R-1405M-PM 4340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 108 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 7564478\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752136835378,"sku":"7564478","price":357.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/793e9676d23eb652919926b7fc44a97c_e3e3122b-aac7-482c-95c4-d9dc17195421.jpg?v=1788926116","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7564478-milling-insert-grade-4340","provider":"Voomi Supply","version":"1.0","type":"link"}
