It features a 3\/4 inch cutting diameter, 1 inch length of cut, and a corner radius range of 0.055 to 0.065 inches. The 4-flute, right-hand cutting geometry paired with an AlTiN coating provides heat and wear resistance at elevated cutting temperatures. The 30-degree helix angle supports efficient chip evacuation, and the center-cutting configuration allows plunge entry. This tool is built for machinists and toolmakers running CNC mills or manual vertical mills in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for profiling, slotting, and finish milling applications where a controlled corner radius is required to reduce stress concentrations on machined parts. The AlTiN coating makes it well-suited for dry or minimal-lubrication cutting in hardened steels, stainless steels, and cast iron. With a 3\/4 inch shank diameter matching the cutting diameter, it seats directly in standard ER or end mill holders without a reducer. The Series 100 designation places it in PROMAX's standard coarse-pitch line for general-purpose hard-material milling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature cutting performance and extended tool life\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.055 to 0.065 inches reduces part stress concentrations\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand coarse-pitch geometry for efficient material removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip flow and surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 3\/4 inch shank corner radius end mills in standard ER collet chucks, end mill holders, and milling machine spindles accepting 3\/4 inch straight shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Secure the shank in a compatible holder to the manufacturer-recommended clamping torque for the holder type in use. Inspect the cutting edges and coating for chips or wear before each use, and verify runout with a dial indicator after seating to confirm proper tool engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 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 Angle\u003c\/strong\u003e: 30 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: Coarse\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\u003eCenter Cutting\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: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100-04824\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52105031024946,"sku":"100-04824","price":313.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b54b09dc3914ffa439f534ba7912468e.jpg?v=1790072467","url":"https:\/\/voomisupply.com\/products\/promax-100-04824-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
