Built on OSG's VGM5 series platform, this single-end tool features 5 helical flutes with a 40-degree helix angle and a variable index geometry that reduces chatter and improves surface finish. The 9\/32-inch cutting diameter and 27\/32-inch length of cut make it well suited for slotting, profiling, and finishing passes on ferrous and non-ferrous workpiece materials. EXO coating enhances heat resistance and tool life. Right-hand cutting and right-hand flute direction are standard. Machinists and toolroom professionals install and operate this tool in CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThe VGM5-0077 is intended for use in precision machining environments where tight tolerances and consistent surface quality are required. Its micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. The center-cutting capability allows for plunge entry, giving the tool versatility across profiling, pocketing, and ramping operations. The straight cylindrical shank with a 9\/32-inch diameter fits standard collet and end mill holder systems commonly found in vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 helical flutes with variable index geometry to reduce vibration and improve finish\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle optimized for chip evacuation and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eEXO coating for extended tool life and improved thermal resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for wear resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production end mill for use in standard collet chucks and end mill holders accepting a 9\/32-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per shop safety procedures. Seat the shank fully in a properly sized collet or end mill holder and torque the retention hardware to the holder manufacturer's specification. Inspect the cutting edges and coating condition before each use. Follow the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 9\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.2813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Fractional)\u003c\/strong\u003e: 27\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Decimal)\u003c\/strong\u003e: 0.8438 inches\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 (Fractional)\u003c\/strong\u003e: 9\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.2812 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Yes\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 Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EXO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin Solid Carbide\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: 0.1 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: VGM5-0077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732006142258,"sku":"VGM5-0077","price":83.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6dde139d5fcbd19b4bd964c6fba7df12_445121b7-7c1d-44d9-aee6-3f600e55dec5.jpg?v=1788737973","url":"https:\/\/voomisupply.com\/products\/osg-vgm5-0077-square-end-mill-9-32-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
