It features a 7\/16-inch cutting diameter, a 3\/4-inch length of cut, and a 3-3\/4-inch overall length, placing it in the extra-long reach category. The 30-degree spiral flute geometry and right-hand cut with right-hand flute configuration promote efficient chip evacuation and stable cutting action. With a 2-1\/4-inch reach length, this tool is well suited for applications requiring access beyond standard reach. Installation and use are handled by CNC machinists and tool-and-die professionals working in ferrous and non-ferrous milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in vertical machining centers, CNC mills, and manual knee mills where extra reach is required to access deep pockets, stepped features, or recessed floors. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled pilot hole. Its uncoated solid carbide construction makes it appropriate for a range of base materials where coating selection is left to the operator or application. The EX-204 series is a dedicated extra-long configuration intended for applications where standard-length tooling cannot reach the cut zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision milling\u003c\/li\u003e\n  \u003cli\u003eExtra-long reach at 2-1\/4 inches, enabling deep-pocket and recessed-floor milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where a specific coating is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill in the ROBBJACK EX-204 series for use in standard 7\/16-inch collet or end mill holder setups on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis end mill is installed and operated by qualified CNC machinists or toolroom personnel. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully and evenly in a matching collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and do not exceed the tool manufacturer recommended speeds and feeds 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: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 \/ -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EX-204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ROBBJACK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EX-204-14\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52005069586738,"sku":"EX-204-14","price":273.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5df8e882ae60ffde88752f7bfef97a50.jpg?v=1789999924","url":"https:\/\/voomisupply.com\/products\/robbjack-ex-204-14-square-end-mill-7-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
