With a 1\/4 inch cutting diameter, five flutes, and a 40-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action on ferrous and non-ferrous materials. The EXO finish enhances wear resistance and extends tool life in demanding cutting environments. The variable index geometry reduces chatter and vibration, improving surface finish quality. This tool is installed by machinists and CNC operators in job shop, production, and toolroom settings.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and profiling operations on CNC machining centers and manual mills. The 1\/4 inch shank diameter matches standard collet and end mill holder sizes common in light to medium-duty milling setups. With a 1 inch length of cut and 3 inch overall length, it is configured for standard-reach applications where rigidity and deflection control are priorities. Micrograin carbide construction supports use in higher-speed cutting programs where tool stability is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute design improves feed rates and surface finish compared to standard 4-flute geometry\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eEXO coating enhances heat resistance and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge milling entries\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides hardness and edge retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for standard 1\/4 inch shank square end mill applications in CNC and manual milling operations requiring a 5-flute, single-end, right-hand cut tool with straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a collet chuck or end mill holder sized for a 1\/4 inch straight-cylindrical shank. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Tighten the tool holder to the manufacturer-specified torque using a torque wrench appropriate for the holder type. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\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: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EXO\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\u003eVariable Helix\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\u003eSeries\u003c\/strong\u003e: VGM5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: VGM5-0063\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730467324210,"sku":"VGM5-0063","price":80.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6dde139d5fcbd19b4bd964c6fba7df12_121ece24-439b-4c38-8d25-a7470cc82bcf.jpg?v=1788717961","url":"https:\/\/voomisupply.com\/products\/osg-vgm5-0063-square-end-mill-1-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
