It features a 0.25-inch diameter, a 0.06-inch corner radius, and five flutes ground from solid carbide. The EXO coating provides elevated hardness and heat resistance, extending tool life in high-temperature cutting environments. A 40-degree high helix angle promotes chip evacuation and reduces cutting forces. Variable index flute spacing helps suppress chatter and vibration during aggressive cuts. Machinists and toolroom operators install this end mill into standard straight-shank toolholders for use on CNC machining centers and milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing and finishing passes on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The short length-of-cut geometry — 0.5 inches — keeps deflection low when profiling, slotting, or contouring in tight cavities. The 2.5-inch overall length fits common tool assemblies without requiring extended-reach holders. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with EXO coating for heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e0.06-inch corner radius reduces stress concentration at the cutting edge and extends tool life\u003c\/li\u003e\n\u003cli\u003eFive-flute design with variable index for chatter suppression and improved surface finish\u003c\/li\u003e\n\u003cli\u003e40-degree high helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral with normal pitch — compatible with standard CNC toolpaths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with straight-shank cylindrical toolholders accepting a 0.25-inch shank diameter.

Secure the 0.25-inch straight shank in a collet or end mill holder to the manufacturer-specified clamping torque for that holder type. Verify runout at the tip before initiating a cut, as excessive runout accelerates edge wear on multi-flute carbide tools. Always power down and lock out the spindle before changing or inspecting tooling in accordance with applicable machine-safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees (High)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EXO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0011 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: VGM5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: VGM5-0056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748732502322,"sku":"VGM5-0056","price":57.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6dde139d5fcbd19b4bd964c6fba7df12_9afa22d4-f077-4a59-9a42-4aac70ac1417.jpg?v=1788897462","url":"https:\/\/voomisupply.com\/products\/osg-vgm5-0056-corner-radius-end-mill-0-25in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
