Measuring 5\/8 inches in diameter with a 1 inch length of cut and a 0.06 inch corner radius, this single-end tool is built for both roughing and finishing operations. The four right-hand helical flutes run at a medium helix angle, promoting efficient chip evacuation and smooth cutting action. An AlTiN (TiAlN) PVD coating provides thermal and wear resistance at elevated cutting temperatures, extending tool life in production environments. It is center-cutting, allowing plunge entry, and is installed in a standard straight cylindrical toolholder by machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThe ISCAR 5621266 is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. Its medium-length flute geometry and submicron carbide grade make it a strong choice for profiling, contouring, and slotting operations on machining centers and CNC mills where consistent corner geometry is critical to part finish and dimensional accuracy. It fits standard toolholders accepting a 5\/8 inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress concentrations and improves surface finish on profiled workpiece edges\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating delivers oxidation resistance and hardness retention at high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade provides high rigidity and edge integrity for hard materials and superalloys\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction with medium helix for balanced chip flow in roughing and finishing\u003c\/li\u003e\n  \u003cli\u003eSeries ECI-E-4R with shank diameter tolerance h6 for precise toolholder fit and minimal runout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 5\/8 inch straight-cylindrical shank.

Power down and lock out the machine spindle before mounting or removing the tool. Secure the shank fully within the toolholder to the manufacturer-specified grip depth and verify runout with a dial indicator before beginning cuts. Inspect the cutting edges for chips or coating damage before each use, especially after interrupted cuts or hard-material applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-E-4R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5621266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51729835884850,"sku":"5621266","price":319.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9e6251092a821210cac28a2bc5df02f.jpg?v=1788709532","url":"https:\/\/voomisupply.com\/products\/iscar-5621266-corner-radius-end-mill-5-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
