It features a 1\/2 inch cutting diameter, a 2-1\/2 inch length of cut, and a 4 inch overall length with a 1\/2 inch shank diameter. The four-flute spiral design runs at a 35-degree helix angle with a TiAlN coating, improving heat resistance and tool life in ferrous and hard materials. Machined from micrograin carbide stock, this end mill is built for high-speed finish and roughing passes where consistent geometry and edge retention are critical. It is installed and used by CNC machinists and tool-and-die professionals in shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling slots, pockets, profiles, and contours in steel, stainless steel, cast iron, and similar materials. The centercutting geometry allows direct plunge entry without a pre-drilled hole, adding flexibility in multi-operation setups. Variable index flute spacing reduces chatter and harmonic vibration during aggressive cuts, making it a practical choice for both roughing and semi-finish passes. The right-hand cut and right-hand spiral flute configuration matches standard CNC spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle with spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2 inch shank square end mill compatible with CNC machining centers, knee mills, and other milling machines accepting 1\/2 inch collets or end mill holders.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or end mill holder and torque to the tool holder specification before running. Verify runout with a dial indicator before committing to a production pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VG441\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 0.75 inches W x 0.75 inches H\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VG441-5012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736363368754,"sku":"VG441-5012","price":192.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1cb27490d67e1b22b640e4adc41999d.jpg?v=1788777472","url":"https:\/\/voomisupply.com\/products\/osg-vg441-5012-square-end-mill-1-2-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
