With a 3\/4 inch (0.7500 inch) mill diameter, four flutes, and an AlTiCrN (aluminum titanium chromium nitride) coating, this end mill delivers wear resistance and thermal stability under demanding cutting conditions. The 38-degree helix angle promotes efficient chip evacuation, and the micrograin carbide substrate supports higher cutting speeds compared to standard carbide grades. It is a single-end tool with a right-hand cut and right-hand flute direction, suited for CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe 311222 is intended for use in industrial and job-shop environments where contoured or radiused surfaces are required. The ball-end geometry makes it well-suited for 3D profiling, slotting, and finishing passes on hardened steels, stainless alloys, and other ferrous materials commonly encountered in die, mold, and general component machining. The standard-length configuration and straight-cylindrical shank make it compatible with conventional collet and end mill holder setups. This tool is selected by machinists and toolmakers who need consistent performance on tight-tolerance contour work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for elevated hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiCrN coating provides oxidation resistance and extended tool life at elevated temperatures\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes smooth cutting action and effective chip removal\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic vibration during cut\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut with straight-cylindrical shank for standard toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eBall-end geometry suited for 3D contouring and radiused profile milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide ball end mill in the ACCUPRO HS Series, compatible with standard 3\/4 inch collets and end mill holders on CNC and conventional milling machines.\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 toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Use a properly sized collet or shrink-fit holder to achieve minimal runout, as excessive runout accelerates edge wear on carbide tooling. Verify cutting parameters against the workpiece material grade before engaging the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches \/ 19.05 mm)\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: 1-5\/8 inches (41.27 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrN\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 311222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733175370034,"sku":"311222","price":339.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21bad62b56be614dbd730899098afe05_73ae604e-6346-4485-b22f-a6a7692e99fd.jpg?v=1788752299","url":"https:\/\/voomisupply.com\/products\/accupro-311222-ball-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
