Part of the ECI-4-VF series, this single-end, centercutting tool features a 1\/2 inch diameter with a 0.015 inch corner radius that reduces stress concentration and extends tool life at the cutting edge. The AlTiCrSiN PVD coating provides thermal resistance and hardness suited to dry or minimum-quantity lubrication cutting. With a right-hand flute direction and right-hand cutting orientation, the 4-flute spiral geometry supports both roughing and finishing passes. This tool is installed by machinists and CNC tooling technicians working on production mills and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The extended reach design and long length type make it suitable for deeper cavity work, shoulder milling, and profiling operations where standard-reach tools cannot access the workpiece geometry. The Weldon flat shank with h6 tolerance ensures secure clamping in compatible Weldon-style toolholders. Variable index geometry helps reduce harmonic vibration during aggressive cuts. It is well suited for job shop and production environments requiring a single tool capable of handling both roughing and finishing on difficult workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating for high heat resistance on steel, stainless, cast iron, superalloys, and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and extends tool life\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 2.0 inch reach length supports deep cavity and shoulder milling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with h6 tolerance for positive anti-pullout clamping\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade for edge integrity in hard material applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Weldon-style toolholders.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Insert the Weldon flat shank fully into the toolholder bore and tighten the set screw against the flat to the toolholder manufacturer specifications to prevent pullout under load. Verify runout with a dial indicator after seating to confirm proper clamping before beginning a cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 inches\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: AlTiCrSiN (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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: Yes\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 and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-4-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 3401073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748139598130,"sku":"3401073","price":147.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76aebafa75cad44d31f5c4a0535535fb_07703d19-0784-4940-9836-f5aab6c3dbed.jpg?v=1788889562","url":"https:\/\/voomisupply.com\/products\/iscar-3401073-corner-radius-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
