It features a 1\/4 inch diameter with a 3\/4 inch length of cut, a 38-degree helix angle, and a TiAlCN coating for extended tool life in high-temperature cutting environments. The submicron carbide grade substrate adds toughness and wear resistance. With 5 flutes and a variable index design, this end mill delivers improved surface finish and reduced chatter compared to standard 4-flute tools. Right-hand cutting and right-hand spiral flute direction are standard. Centercutting capability allows plunge entry into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish and semi-finish milling of ferrous and non-ferrous materials in CNC machining centers. The 1\/4 inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit toolholders. The 2.5 inch overall length provides good rigidity in typical tool-length configurations. It is installed and operated by machinists and CNC operators working in job shop, aerospace, automotive, and general manufacturing environments. The TiAlCN coating supports dry or near-dry cutting, making it compatible with high-speed machining strategies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlCN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e5 flutes with variable index geometry reduce harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers accepting 1\/4 inch shank end mills via ER collet, end mill holder, or shrink-fit toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per standard lockout\/tagout procedures. Ensure the shank is fully seated in the toolholder and that the collet or set screw is torqued according to the toolholder manufacturer specifications. Verify runout with a dial indicator before cutting. Consult the machining center programming documentation for appropriate feeds, speeds, and depth-of-cut parameters 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: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3398541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728197615922,"sku":"3398541","price":58.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_de979316-ae2a-43dd-a538-4e6fe21358d7.jpg?v=1788689365","url":"https:\/\/voomisupply.com\/products\/iscar-3398541-square-end-mill-1-4-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
