It features a 9\/64 inch (0.1406 inch) cutting diameter and a 1\/2 inch length of cut, making it well suited for slotting, profiling, and peripheral milling in tight-tolerance work. The 4-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting geometry allows the tool to plunge directly into the workpiece. At 2 inches overall length with a 3\/16 inch shank diameter, this end mill fits standard collet chucks used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in professional machine shop environments and production environments where small-diameter precision cutting is required. The uncoated micrograin solid carbide construction is appropriate for dry cutting or use with cutting fluids in ferrous and non-ferrous materials. Its compact size makes it particularly useful for fine detail work, small pocket milling, and finishing passes where larger tools cannot reach. The Series 404 designation places it within OSG's standard square end mill line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance in precision cuts\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle use\u003c\/li\u003e\n\u003cli\u003e3\/16 inch shank fits common collet sizes on CNC and manual milling machines\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a range of dry and wet cutting applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank square end mill compatible with 3\/16 inch collets and collet chucks on CNC machining centers and manual milling machines that accept small-diameter tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine powered down. Secure the shank fully within the collet to the recommended engagement depth and verify runout before initiating a cut. Follow the tool manufacturer and machine manufacturer guidelines for feeds, speeds, and depth of cut. Do not use damaged or excessively worn collets, as poor clamping increases runout and can cause premature tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/64 inch (0.1406 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 404-1406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736823234866,"sku":"404-1406","price":33.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24620e9677c38e8c52a68757970c43f8.jpg?v=1788780778","url":"https:\/\/voomisupply.com\/products\/osg-404-1406-square-end-mill-9-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
