With a 7\/64 inch (0.1094 inch) cutting diameter and a 4-flute spiral geometry, this tool delivers clean, accurate cuts in ferrous and non-ferrous materials. The right-hand cut and right-hand flute configuration is standard for conventional CNC and manual milling setups. A 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. This end mill is centercutting, allowing plunge entry directly into the workpiece. It is installed and used by machinists and CNC operators working in job shops, production facilities, and toolrooms.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and pocketing operations in small-scale precision work where tight tolerances are required. The 7\/16 inch length of cut and 1-1\/2 inch overall length make it well-suited for shallow-to-medium depth cuts. The straight cylindrical 1\/8 inch shank fits standard collets and toolholders in that size range. The uncoated C2 carbide grade is appropriate for general-purpose milling where coating is not required or where re-sharpening is anticipated.\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\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute  -  compatible with standard CNC spindle direction\u003c\/li\u003e\n  \u003cli\u003eUncoated C2 carbide grade suitable for general-purpose and re-sharpenable applications\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 1\/8 inch shank fits standard collets in that size range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills using 1\/8 inch collets or toolholders; part of the ROBBJACK NR-404 series of solid carbide square end mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before installing or removing end mills. Secure the shank fully within the collet to the recommended engagement depth and torque the collet nut to the toolholder specification. Verify runout after installation before beginning a cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\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: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inch (1.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: NR-404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: NR-404-03.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51960015847730,"sku":"NR-404-03.5","price":46.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a913e66a6f6169f1917b63fcf4a43218_5b7ba4eb-3571-4873-8f67-f6cb72530604.jpg?v=1789946041","url":"https:\/\/voomisupply.com\/products\/robbjack-nr-404-03-5-square-end-mill-7-64-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
