It is constructed from micrograin solid carbide for superior rigidity, edge retention, and thermal resistance under demanding cutting conditions. The tool measures 0.75 inches in diameter with a matching 0.75-inch shank diameter and a 6.25-inch overall length. A TiAlN coating provides oxidation resistance and extended tool life at elevated temperatures. The 4-flute, 30-degree right-hand spiral geometry promotes efficient chip evacuation and smooth surface finishes. Licensed machinists and CNC tool-and-die professionals are the primary installers and operators of this tool.\u003c\/p\u003e\n\u003cp\u003eThe EM21004801 is suited for mold and die work, aerospace component machining, and general-purpose profiling operations on vertical and horizontal machining centers. Its extended reach configuration, with a reach length of 2.25 inches and a length of cut of 0.75 inches, makes it appropriate for applications requiring clearance around workpiece features or fixture components. The right-hand cutting direction is compatible with standard spindle rotation on most CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for high rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for oxidation resistance and extended tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand spiral geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 2.25-inch reach length for clearance-critical applications\u003c\/li\u003e\n  \u003cli\u003eBall end profile for 3D contouring, radius milling, and profiling operations\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with consistent shank and cutter diameter at 0.75 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders, shrink-fit chucks, and collet chucks accepting a 0.75-inch shank diameter on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from its holder. Verify holder bore diameter and runout tolerance before seating the shank, as excessive runout will degrade surface finish and accelerate tool wear. Follow machine tool manufacturer torque specifications for the chosen toolholding system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 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: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0005 to -0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EM21004801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734827761970,"sku":"EM21004801","price":1060.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecb74055adba4cf2f4f9ea66f197a951.jpg?v=1788767191","url":"https:\/\/voomisupply.com\/products\/accupro-em21004801-ball-end-mill-0-75in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
