It features a 7\/16 inch (0.4375 inch) mill diameter, a 1-1\/2 inch length of cut, and a 4 inch overall length with a 7\/16 inch shank diameter. The tool carries an AlTiCrSiN coating, a 38-degree helix angle, and a variable index geometry across four spiral flutes. Submicron grain carbide substrate supports rigidity and edge retention under aggressive cutting conditions. This is a single-end, right-hand cut, right-hand flute tool suited for machinists working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 3398295 is engineered for milling hardened materials, cast iron, stainless steel, carbon and alloy steels, and high-temperature alloys. The AlTiCrSiN coating performs well in dry and near-dry cutting where heat resistance at the cutting edge is critical. The variable index flute spacing reduces harmonic chatter, making it a practical choice for side milling, slotting, and finishing passes where surface finish and tool life both matter. Licensed machinists and CNC tooling specialists are the primary installers and operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grain substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiCrSiN coating rated for hardened materials, stainless, cast iron, steel, and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes efficient chip evacuation in spiral flute geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with right-hand cut and right-hand flute orientation\u003c\/li\u003e\n  \u003cli\u003eECI-4-VF series construction in fractional inch measurement system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 7\/16 inch collet or end mill holders on CNC machining centers and manual mills.

Ensure the machine spindle and tool holder are free of chips and burrs before seating the shank. Follow the machine tool manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and depth of cut. Inspect the cutting edges for wear or chipping before each use and replace the tool if edge condition is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrSiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-4-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Hardened Materials, Cast Iron, Stainless Steel, Steel, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: 3398295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727313895730,"sku":"3398295","price":111.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_ae4eda9b-1168-46b6-842d-4fb9bc2d220d.jpg?v=1788676204","url":"https:\/\/voomisupply.com\/products\/iscar-3398295-square-end-mill-7-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
