It features a 3\/4-inch cutting diameter, a 1-5\/8-inch length of cut (LOC), and a corner radius ranging from 0.055 to 0.065 inches. The four-flute, right-hand cutting geometry is combined with a high-helix design and an AlTiN coating, making it well-suited for high-speed machining of hardened steels, stainless steels, and other demanding alloys. Overall length is 4 inches with a 3\/4-inch shank diameter. Installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal CNC machining centers as well as manual mills for profiling, slotting, and peripheral milling where a radius corner break is specified on the finished part. The centercutting design allows plunge entry directly into the workpiece. Fine pitch flute spacing and right-hand flute direction support efficient chip evacuation in tight-tolerance cuts on ferrous and non-ferrous materials. The AlTiN coating provides thermal resistance for dry or minimal-lubrication machining applications at elevated surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch cutting diameter with a 1-5\/8-inch length of cut for deep-reach profiling\u003c\/li\u003e\n  \u003cli\u003eCorner radius range of 0.055 to 0.065 inches reduces edge chipping and stress risers on finished parts\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature resistance for dry and high-speed machining of hardened materials\u003c\/li\u003e\n  \u003cli\u003eFour-flute, high-helix, right-hand geometry promotes smooth cutting action and effective chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in demanding cutting conditions\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\/4-inch ER or side-lock tool holders used in CNC machining centers and manual milling machines requiring a 3\/4-inch shank end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Use a calibrated torque wrench on collet nuts to avoid over-tightening, and verify runout with a dial indicator before commencing cuts. Follow the tooling manufacturer and machine OEM guidelines for recommended surface footage and feed rates based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.055 to 0.065 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101-04814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51974330548530,"sku":"101-04814","price":404.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1b3af3ce14a7a3285960c83dd4a01c3.jpg?v=1789977007","url":"https:\/\/voomisupply.com\/products\/promax-101-04814-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
