It features a 0.0625 inch cutting diameter, a 3\/16 inch length of cut, and a 1\/8 inch shank diameter with a 1-3\/4 inch overall length. Constructed from solid carbide micrograin material, this tool delivers consistent edge integrity in demanding cutting conditions. The diamond finish coating reduces friction and extends tool life in abrasive or hardened workpiece materials. A 30-degree helix angle promotes chip evacuation while maintaining smooth cutting action. This end mill is installed by machinists and toolroom technicians working in CNC milling centers, vertical mills, and precision machining cells.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and contouring operations where a small-diameter tool is required. The 4-flute, spiral-flute configuration supports higher feed rates compared to 2-flute designs in non-recutting applications. Its centercutting capability allows plunge entry directly into the workpiece. The 0.056 inch neck diameter provides clearance for work in confined pockets. This tool is appropriate for use in ferrous and non-ferrous materials in both production and prototype environments where tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0625 inch cutting diameter with mill diameter tolerance of +0.000 \/ -0.002 inches for consistent sizing\u003c\/li\u003e\n  \u003cli\u003eSolid carbide micrograin construction for edge stability in fine-detail milling\u003c\/li\u003e\n  \u003cli\u003eDiamond finish for reduced friction and improved tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut, right-hand spiral flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting forces and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e0.056 inch neck diameter provides clearance for deep-pocket and confined-area work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application end mill for CNC milling machines and manual mills accepting a 1\/8 inch straight shank collet, ER collet chuck, or equivalent toolholder sized for 0.125 inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and machine is powered down before inserting or removing the tool from the collet or toolholder. Verify collet size matches the 0.125 inch shank diameter exactly before tightening. Do not exceed the recommended depth of cut for the 3\/16 inch length of cut, and confirm workholding is secure before initiating the cut to prevent tool deflection or breakage at this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.056 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1\/2 inch\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 7040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 70400316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":52051372441906,"sku":"70400316","price":176.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f243b264e812e19eea6b3d45bc044ae0.jpg?v=1790034736","url":"https:\/\/voomisupply.com\/products\/osg-70400316-square-end-mill-1-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
