It features a 3\/4 inch mill diameter, a 2.75 inch length of cut, and a 5 inch overall length. The AlCrTiN coating provides high heat resistance and extended tool life in high-speed and dry cutting applications. With five flutes and a 38-degree helix angle, this end mill delivers efficient chip evacuation and a high-quality surface finish. Variable index spacing reduces chatter and vibration during aggressive passes. It is a single-end, centercutting tool, allowing plunge entry as well as peripheral milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills in job shop, production, and tool and die environments. The corner radius geometry — 0.12 inch radius — reduces stress concentrations at the cutting corner, extending tool life compared to square-end geometries. It is appropriate for profiling, slotting, and finishing passes where corner strength and surface finish are critical. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC setups. The micrograin carbide substrate provides toughness and wear resistance in demanding cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature resistance and extended tool life in hard and dry cutting\u003c\/li\u003e\n\u003cli\u003eFive-flute design with 38-degree helix for efficient chip evacuation and smooth finish\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and vibration during heavy passes\u003c\/li\u003e\n\u003cli\u003e0.12 inch corner radius reduces edge stress and extends tool life versus square-end geometry\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry without a pre-drilled pilot\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers consistent edge integrity in demanding 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 corner radius end mill for CNC machining center spindles accepting a 3\/4 inch shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Use a properly sized collet or end mill holder rated for a 3\/4 inch shank to achieve correct runout and clamping force. Do not exceed the tool or spindle manufacturer recommended speeds and feeds for the workpiece material and coating type.\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 inches)\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: 2.75 inches (69.85 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 mm)\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: 0.12 inches\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\u003eExtended Reach\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 311828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729006199090,"sku":"311828","price":408.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8254d0ae7b10182ca163db3aac307e6_4326907b-603b-4ac5-bd14-c4218924da98.jpg?v=1788698739","url":"https:\/\/voomisupply.com\/products\/accupro-311828-corner-radius-end-mill-3-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
