With a 5\/32-inch (0.1563-inch) mill diameter and a 9\/16-inch length of cut, this tool delivers accurate material removal in tight-tolerance environments. The 4-flute, right-hand spiral configuration promotes efficient chip evacuation and smooth cutting action. The 3\/16-inch straight cylindrical shank and 2-inch overall length make it well-suited for use in standard collet and end mill holders on vertical mills and CNC machining centers. It is uncoated and built to the TR-404 Series specification using ROBBJACK Tuffy-grade carbide.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in job shops, tool rooms, and production environments where small-diameter precision milling is required. The centercutting geometry allows for plunge entry as well as peripheral and slot milling. The 30-degree helix angle provides a balance of cutting efficiency and edge strength suitable for ferrous and non-ferrous materials. Machinists and CNC operators working with aluminum, brass, mild steel, and similar materials will find this tool appropriate for finish milling, profiling, and light slotting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide Tuffy-grade construction for rigidity and wear resistance in small-diameter tooling\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral flute design for efficient chip removal and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting forces across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and end mill holders without modification\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where coating is not required or where regrinding is anticipated\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 3\/16-inch shank collets and end mill holders used in vertical milling machines and CNC machining centers requiring small-diameter square end mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the machine spindle is fully stopped and locked out before changing or setting tooling. Confirm collet condition and cleanliness before seating the shank to maintain concentricity within acceptable runout limits. Refer to the tooling manufacturer feed and speed recommendations for the specific material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 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: Tuffy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: TR-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: TR-404-05\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51972384620850,"sku":"TR-404-05","price":67.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e54d9ab00f14d31865f340693033e14.jpg?v=1789967293","url":"https:\/\/voomisupply.com\/products\/robbjack-tr-404-05-square-end-mill-5-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
