With a 1\/4 inch cutting diameter and a 3\/4 inch length of cut, this single-end tool is built for finishing and semi-finishing passes where chip evacuation and surface finish quality are priorities. The EXO coating provides thermal resistance and reduces friction at the cutting edge. The 36-degree helix angle promotes smooth cutting action and effective chip flow. Variable index flute spacing reduces harmonic vibration during high-speed operation, extending tool life and improving surface quality. Machinists and CNC operators running ferrous and non-ferrous materials will find this geometry well-suited to high-speed finishing strategies.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual milling machines for finishing cuts, contour milling, and slot milling applications. The 1\/4 inch straight cylindrical shank fits standard collet chucks and end mill holders in common spindle sizes. With a 2.5 inch overall length and regular length designation, it fits compact workholding setups with limited Z-axis clearance. The non-centercutting design means it is not intended for direct plunge entry. Right-hand flute direction and right-hand cutting orientation follow standard convention for most CNC programming environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute geometry increases radial contact for improved finish and higher feed rates in finish milling\u003c\/li\u003e\n\u003cli\u003eEXO coating reduces friction and heat buildup at the cutting edge, extending tool life\u003c\/li\u003e\n\u003cli\u003e36-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces vibration and chatter during high-speed passes\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction provides hardness and edge retention across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral configuration compatible with standard CNC toolpaths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or toolholder and torque the retention nut to the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning the first cut, as excessive runout on a 7-flute tool accelerates uneven wear.\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\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 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\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EXO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VGM7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VGM7-0009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731969671474,"sku":"VGM7-0009","price":53.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d76d3b2ee379b3fe71cfda3fdd1afb52_ff7969c5-6a55-402e-8580-799f5ee5410e.jpg?v=1788737399","url":"https:\/\/voomisupply.com\/products\/osg-vgm7-0009-square-end-mill-1-4-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
