Part of the TR-404 series in the Tuffy material grade, this tool features a 0.750 inch mill diameter, a 1.5 inch length of cut, and a 4 inch overall length. The straight cylindrical shank measures 0.750 inches in diameter for secure toolholder engagement. With 4 spiral flutes and a 30-degree helix angle, it is built for right-hand cut and right-hand flute rotation. Centercutting capability allows plunge entry. Licensed machinists, CNC operators, and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThe TR-404-24 is suited for general-purpose milling operations including slotting, profiling, and pocketing in ferrous and non-ferrous metals. The regular-length geometry fits standard machining center setups where tool clearance is not a constraint. The uncoated solid carbide construction performs well in applications where coolant is applied and consistent edge sharpness is required. This is a single-end tool, so once the cutting end is worn, the tool is replaced rather than indexed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in the Tuffy material grade for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with a 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with tight shank diameter tolerance of -0.0001 to -0.0002 inches\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with coolant in a variety of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 3\/4 inch toolholders including collet chucks, end mill holders, and shrink-fit systems compatible with straight cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machining professionals during CNC or manual milling machine setup. Ensure the spindle is fully stopped and the machine is in an E-stop or locked-out state before changing tooling. Seat the shank fully into the toolholder and torque the retention hardware to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-404-24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51988861190450,"sku":"TR-404-24","price":542.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e54d9ab00f14d31865f340693033e14_08a3aded-6e94-47a5-826c-e8276163f0ff.jpg?v=1789987903","url":"https:\/\/voomisupply.com\/products\/robbjack-tr-404-24-square-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
