It features both variable helix and variable index geometry, which work together to disrupt harmonic vibration and reduce chatter during cutting operations. The 1\/2 inch mill diameter pairs with a 1\/2 inch straight-cylindrical shank, and the tool delivers a 1-1\/4 inch length of cut across a 3 inch overall length. A bright (uncoated) finish and a 40 to 43 degree variable helix angle make this tool well suited for demanding material removal in aluminum and other non-ferrous alloys. It is center-cutting, allowing plunge entry.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and similar milling equipment found in job shops, production facilities, and toolrooms. The VGM3-AL series designation indicates it is optimized for aluminum alloy cutting, where surface finish, chip evacuation, and minimizing built-up edge are primary concerns. Right-hand cut and right-hand flute configuration is standard for conventional vertical and horizontal milling setups. It is installed and operated by machinists and CNC programmers working in metalworking environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix angles (40, 41, 42, and 43 degrees) reduce harmonic chatter during high-speed passes\u003c\/li\u003e\n\u003cli\u003eVariable index geometry distributes cutting forces unevenly to suppress vibration\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to high-speed steel tooling\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eBright finish suits non-ferrous and aluminum applications where coating adhesion is not required\u003c\/li\u003e\n\u003cli\u003eShank diameter tolerance to h6 standard for consistent tool holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for 1\/2 inch collet chucks, end mill holders, and hydraulic or shrink-fit tool holders accepting a 1\/2 inch straight-cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Use a calibrated tool holder with the correct bore size and verify runout with a dial indicator after seating the shank. Follow the tool manufacturer and machine builder guidelines for recommended speeds, feeds, and depth of cut for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40, 41, 42, 43 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (uncoated)\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\u003eFlute Type\u003c\/strong\u003e: Variable Index\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VGM3-AL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.395 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VGM3-0028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729440276786,"sku":"VGM3-0028","price":118.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/109b59586430a61136c42672a3d7384f_292fc378-1684-4b0f-9d33-6d303d1e5d0f.jpg?v=1788704659","url":"https:\/\/voomisupply.com\/products\/osg-vgm3-0028-variable-geometry-end-mill-1-2-inch-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
