It features a 1-inch mill diameter, a 4-inch length of cut, and a 7-inch overall length with a 1-inch shank diameter. The cutting geometry uses a 4-flute spiral flute configuration with a 35-degree helix angle and a TiAlN (titanium aluminum nitride) coating to extend tool life under high-heat cutting conditions. Variable index flute spacing reduces harmonic vibration during aggressive cuts. This tool is intended for use by machinists and tool-and-die professionals on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThe VG441-1004 is suited for side milling, slotting, and profiling operations on ferrous and non-ferrous metals including alloy steels, stainless steels, and cast iron. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. The right-hand cut, right-hand flute orientation is the standard configuration for most vertical machining center setups. This tool is not center-cutting and is not intended for plunge entry. It fits applications requiring a 4-inch depth-of-cut range, making it appropriate for deep-pocket and long-reach milling work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with 4-inch length of cut for deep-pocket milling\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for extended tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle with variable index spacing to reduce chatter and vibration\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration optimized for finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC machining center compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill in the OSG VG441 series, suitable for use in standard 1-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized end mill holder or collet rated for a 1-inch shank and torque to the toolholder manufacturer specification. Verify runout with a dial indicator after installation before beginning a cut, as excessive runout will accelerate tool wear and reduce surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 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: 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 inches L x 1.25 inches W x 1.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VG441\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: VG441-1004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727210053938,"sku":"VG441-1004","price":891.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a725e360f0f264e98dd41d837852fa09.jpg?v=1788674758","url":"https:\/\/voomisupply.com\/products\/osg-vg441-1004-square-end-mill-1-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
