It features a 5\/8-inch cutting diameter, a 0.03-inch corner radius, and four flutes with a variable helix and variable index geometry. The AlTiN (TiAlN) PVD coating provides thermal resistance and wear protection at elevated cutting temperatures. The overall length is 4 inches, with a 1-1\/4-inch length of cut and a 5\/8-inch Weldon flat shank. This is a center-cutting, single-end tool ground from submicron carbide grade, suited for both roughing and finishing passes. It is installed and operated by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is part of the ISCAR ECI-H4R-CF Chatter Free series, which is engineered to reduce vibration in long-reach and deep-pocket applications. It is rated for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The right-hand flute direction and right-hand cutting geometry make it compatible with standard vertical and horizontal CNC machining centers. The short flute length classification and Weldon flat shank suit it for rigid, high-torque toolholder setups where pullout resistance is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03-inch corner radius reduces stress concentration and extends tool life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry in the Chatter Free series design suppresses vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides oxidation resistance and hardness at high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eSolid submicron carbide construction maintains edge integrity in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive engagement in set-screw toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon flat toolholders.

Seat the Weldon flat shank fully into the toolholder before tightening the set screw to the toolholder manufacturer specification. Verify runout with a dial indicator before first use, as excessive runout accelerates corner radius wear and reduces surface finish quality. Coolant-through is not supported on this tool; use external coolant or air blast as appropriate for the workpiece material.\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\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eReach Length\u003c\/strong\u003e: 1.8700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (TiAlN), PVD\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: e8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-H4R-CF\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: 5623086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753147760946,"sku":"5623086","price":387.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4232052db734741e88f2517b5ab0fd5_4d61d579-a7d7-41cd-9881-b58bd8bc0495.jpg?v=1788933257","url":"https:\/\/voomisupply.com\/products\/iscar-5623086-corner-radius-end-mill-5-8-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
