Built on OSG Series 9140, this tool features six flutes with a 45-degree helix angle and a right-hand spiral flute configuration, producing efficient chip evacuation and smooth surface finishes. The EXO coating provides enhanced wear resistance and heat reduction at the cutting edge. With a 0.315-inch cutting diameter and a 0.748-inch length of cut, this end mill is suited for slotting, profiling, and finish passes in ferrous and non-ferrous materials. Micrograin carbide construction delivers consistent edge integrity across extended run times. Licensed machinists and CNC operators are the primary installers of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard toolholding systems that accept an 0.315-inch shank diameter, including collet chucks and shrink-fit holders commonly found on vertical and horizontal machining centers. The regular length profile and non-extended-reach geometry make it appropriate for general-purpose cavity and contour milling at moderate depths. It is centercutting, allowing plunge entry where required. Typical applications include die and mold work, fixture machining, and production part milling where a 6-flute finish geometry is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eSix-flute design increases feed rate potential and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eEXO coating enhances thermal resistance and extends tool life\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholding systems accepting a 0.315-inch shank diameter; compatible with standard collet, shrink-fit, and milling chuck setups on CNC machining centers using Series 9140 tooling specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or placed in an e-stop state before changing tooling. Seat the shank to the full recommended gauge depth in the holder and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine builder guidelines for appropriate speeds, feeds, and depth-of-cut parameters for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.315 inches (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.748 inches (19 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eCoating\/Finish\u003c\/strong\u003e: EXO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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: 9140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 91400811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747576578354,"sku":"91400811","price":238.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c863dcc3839228ceda3ffadfe5384ac_cb1e65f1-4f79-4ded-8b38-6fd47cf82a52.jpg?v=1788882841","url":"https:\/\/voomisupply.com\/products\/osg-91400811-square-end-mill-0-315-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
