With a 0.25-inch cutting diameter, a 5\/8-inch length of cut, and six flutes ground to a 43-degree helix angle, this tool delivers efficient chip evacuation and a smooth surface finish in a wide range of workpiece materials. The DUROREY finish adds wear resistance, extending tool life in production environments. It is centercutting, allowing plunge entry directly into the workpiece. Machinists, tool-and-die makers, and CNC operators working in job shops or production facilities will find this end mill well-suited to both roughing and finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical machining centers, CNC mills, and manual knee mills where a 1\/4-inch shank and compact geometry are required. At 2-1\/2 inches overall length with a 1\/4-inch shank diameter, it fits standard ER collet chucks and end mill holders in that size range. The right-hand cut and right-hand flute configuration is the industry-standard orientation for conventional CNC milling setups. Applications include slotting, profiling, and peripheral milling in ferrous and non-ferrous metals, plastics, and composites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-flute geometry increases feed rates and improves finish compared to 2- or 4-flute designs in finishing operations\u003c\/li\u003e\n\u003cli\u003e43-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eDUROREY finish provides enhanced surface hardness and wear resistance for longer tool life\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction maintains rigidity and edge sharpness at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration suits standard CNC mill spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any CNC or manual milling machine accepting a 1\/4-inch shank end mill holder or ER collet chuck of the corresponding bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and locked out before inserting or removing tooling. Seat the shank fully into the collet or end mill holder to the recommended minimum engagement depth and torque the retention nut or set screw per the tool holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use.\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: DUROREY\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\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: 0.02 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: 84400823\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748954276146,"sku":"84400823","price":102.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46a3254f5acde6e640620cad36430345_29d3f3c8-1fea-4199-9cb3-8032002e4d4c.jpg?v=1788900448","url":"https:\/\/voomisupply.com\/products\/osg-84400823-square-end-mill-1-4-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
