Built to Series 3150 standards, this single-end mill features a 0.2813-inch cutting diameter, a 0.75-inch length of cut, and a 30-degree helix angle with right-hand spiral fluting. The four-flute geometry provides efficient chip evacuation and a stable cutting action suited to ferrous and non-ferrous materials. At 2.5 inches overall length with a 0.3125-inch shank diameter, it fits standard collet and end mill holders on vertical mills, machining centers, and CNC routers. It ships bright and uncoated, which is appropriate for applications where coating is unnecessary or where re-grinding is anticipated.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in professional machine shop environments, production facilities, and toolroom applications where dimensional accuracy and consistent surface finish are required. The regular-length flute geometry makes it a practical choice for slotting, peripheral milling, and light profiling in both ferrous and non-ferrous workpieces. It is not center-cutting, so plunge operations require a pre-drilled entry point. Machinists and CNC programmers working with small-diameter tooling in tight-tolerance applications will find the solid carbide construction appropriate for maintaining rigidity at elevated spindle speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2813-inch (9\/32 inch) cutting diameter for small-feature and narrow-slot work\u003c\/li\u003e\n  \u003cli\u003eFour flutes with right-hand spiral cut and 30-degree helix angle\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance at high RPM\u003c\/li\u003e\n  \u003cli\u003e0.75-inch length of cut in a regular-length configuration\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose or re-grindable tooling programs\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting — requires pre-drilled entry for plunge moves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard 5\/16-inch collet chucks and end mill holders on manual vertical mills and CNC machining centers where small-diameter tooling is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the 0.3125-inch shank fully into the collet or holder to the recommended engagement depth before torquing the retention mechanism. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear on small-diameter solid carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2813 inches (9\/32 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: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eSeries\u003c\/strong\u003e: 3150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9031500071400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753862005042,"sku":"9031500071400","price":67.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34ec7aed6b5c0d43528106181c089316_c4bd94ce-061e-480a-b062-ab84db62a7d3.jpg?v=1788941593","url":"https:\/\/voomisupply.com\/products\/guhring-9031500071400-square-end-mill-0-2813-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
