It features a 3\/8 inch diameter cutting edge with a 1-1\/4 inch length of cut and a 3\/4 inch shank diameter, yielding a 3 inch overall length. The four-flute, right-hand spiral geometry combined with a 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiAlCN coating improves wear resistance and thermal stability during high-speed cutting. The submicron carbide grade provides the hardness and toughness needed for demanding milling operations. Single-end construction and center-cutting capability allow plunge entry and peripheral milling from a single tool. Licensed machinists and CNC operators are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for ferrous and non-ferrous machining on vertical and horizontal CNC machining centers as well as manual knee mills. The extended-reach design and 1-1\/4 inch reach length allow access to deeper pockets and shoulder features without tool-holder interference. Variable index flute spacing reduces harmonic chatter during aggressive cuts. It is appropriate for production environments where consistent surface finish and dimensional accuracy are required across medium to high hardness workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for hardness and toughness in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlCN coating for improved wear resistance and elevated-temperature performance\u003c\/li\u003e\n  \u003cli\u003e38-degree right-hand helix promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index flute geometry minimizes chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 1-1\/4 inch reach length for deeper pocket and shoulder access\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement end mill for CNC and manual milling machines accepting a 3\/4 inch straight shank toolholder.

Power down and lock out the machine spindle before seating or removing the end mill from the toolholder. Ensure the shank is fully seated to the correct insertion depth specified by the toolholder manufacturer and that set screws or collet nuts are torqued per the toolholder documentation. Inspect the cutting edges and coating for chips or damage before each use; a damaged tool can cause workpiece defects or tool breakage under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003c\/strong\u003e: TiAlCN\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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 3401266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51744696467762,"sku":"3401266","price":100.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64a8d7d8b576880607b0dcef83a05229.jpg?v=1788859980","url":"https:\/\/voomisupply.com\/products\/iscar-3401266-square-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
