Built to the HS series specification, it features a 3\/4 inch diameter, a 2-3\/4 inch length of cut, and a 5-inch overall length. The AlCrTiN coating provides high heat and oxidation resistance, making this tool well-suited for high-speed and dry cutting conditions. With five flutes, a 38-degree helix angle, variable index, and a 0.060 inch corner radius, the 311824 delivers efficient chip evacuation and reduced radial cutting forces. It is single-end and centercutting, allowing plunge entry. Machinists and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for milling slots, pockets, profiles, and contours where a defined corner radius is required to reduce stress concentrations in finished parts. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC vertical and horizontal machining centers. The 3\/4 inch shank diameter matches directly to standard ER and side-lock tool holders. The micrograin carbide substrate supports high feeds and speeds in steel, stainless, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating supports high-temperature and dry cutting applications\u003c\/li\u003e\n\u003cli\u003e5-flute design increases feed rate capability compared to 4-flute equivalents\u003c\/li\u003e\n\u003cli\u003eVariable index reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003e0.060 inch corner radius extends tool life and reduces part stress risers\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers accepting a 3\/4 inch shank diameter toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and toolholder are clean and free of chips before seating the shank. Torque the toolholder to the machine manufacturer specification using the appropriate wrench — do not use impact tools. Confirm runout with a dial indicator before cutting, as excessive runout accelerates wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 311824\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739236237618,"sku":"311824","price":413.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23e22f9189f6bdebfe65401ad5d3e1e5.jpg?v=1788811897","url":"https:\/\/voomisupply.com\/products\/accupro-311824-corner-radius-end-mill-3-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
