It features both variable helix angles ranging from 40 to 43 degrees and variable index flute spacing, which work together to reduce chatter and improve surface finish at higher feed rates. The 1\/4-inch diameter cutting edge has a length of cut of 5\/8 inches and runs on a 1\/4-inch straight cylindrical shank. This tool is center-cutting and configured for right-hand cut with right-hand flute direction. It ships with a bright finish and no chipbreaker. Machinists and CNC operators in metalworking and fabrication shops are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThe VGM3-0009 belongs to the OSG VGM3-AL series, which targets aluminum and non-ferrous materials where chatter suppression and finish quality are critical. It suits applications in precision machining centers and CNC mills running full-depth slotting, peripheral milling, or profiling passes. The overall length of 2-1\/2 inches and regular-length classification make it appropriate for standard reach setups without extended reach requirements. This tool is a practical choice for shops needing a variable geometry option in the 1\/4-inch diameter range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix angles from 40 to 43 degrees reduce harmonics and chatter during cut\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing further dampens vibration for improved surface finish\u003c\/li\u003e\n\u003cli\u003e3 flutes in solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating keeps geometry clean for non-ferrous applications\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\u003ePart of the OSG VGM3-AL series.

Secure the shank in a collet or end mill holder rated for 1\/4-inch h6 tolerance shank diameter and confirm runout before cutting. Power down and lock out the spindle before changing tooling. Follow shop-standard speeds and feeds for the work material and do not exceed the rated length of cut to avoid deflection or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40, 41, 42, 43 degrees (variable)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VGM3-AL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: VGM3-0009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752241725746,"sku":"VGM3-0009","price":52.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/109b59586430a61136c42672a3d7384f_cc1fe7fe-cfbb-4aa1-8580-7f514b328a87.jpg?v=1788926869","url":"https:\/\/voomisupply.com\/products\/osg-vgm3-0009-variable-geometry-end-mill-3-flute-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
