With a 3\/4-inch milling diameter, a 4-inch length of cut, and four flutes, this tool delivers efficient material removal and surface finish quality in demanding machining environments. The TiAlCN coating improves heat and wear resistance at elevated cutting temperatures. The variable index geometry reduces harmonic vibration, making it well-suited for high-speed and high-feed applications. Machinists and CNC operators in job shops, aerospace, die-mold, and general manufacturing work with this tool category daily.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard CNC machining centers and manual mills using a 3\/4-inch collet or end mill holder. The 7-inch overall length and 4-inch length of cut support slotting, profiling, and peripheral milling in medium-to-deep cavity work. The 38-degree helix angle promotes aggressive chip evacuation. Single-end construction means the tool is replaced rather than flipped when the cutting edge is spent. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation on most machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade substrate for rigidity and edge retention in tough materials\u003c\/li\u003e\n  \u003cli\u003eTiAlCN coating provides thermal barrier and oxidation resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes efficient chip evacuation from the flute channel\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry as well as side milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral configuration matches standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4-inch end mill holders, collet chucks, or hydraulic\/shrink-fit toolholders on CNC machining centers and manual knee mills accepting straight-shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before loading or removing the tool. Seat the shank to the minimum insertion depth recommended by the toolholder manufacturer to prevent pull-out under cutting load. Inspect the cutting edges and coating condition before each use; do not run a chipped or heavily worn end mill, as edge failure can damage the workpiece and toolholder.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.750 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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: TiAlCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCenter Cutting\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\u003eVariable Helix\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\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: 3401339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732544192818,"sku":"3401339","price":409.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_e4726133-40ed-4227-822f-9ada06ec1673.jpg?v=1788744265","url":"https:\/\/voomisupply.com\/products\/iscar-3401339-square-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
