Built from micrograin carbide, it delivers a sharp, durable cutting edge suited for ferrous and non-ferrous materials. The 4-flute configuration provides a balance of chip evacuation and surface finish quality. With a 0.125 inch cutting diameter, a 0.25 inch length of cut, and a 30-degree helix angle, this stub-length end mill is well suited for short-reach slotting, profiling, and peripheral milling in CNC machining centers and manual mills. It is centercutting, allowing plunge entry directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is used in tool and die, mold making, precision part manufacturing, and general-purpose shop machining. Its stub length and matched shank-to-cutter diameter make it a practical choice when rigidity is a priority in tight-clearance or shallow-depth applications. The right-hand cut and right-hand spiral flute orientation are standard for conventional CNC spindle setups. Machinists and CNC operators in production and job shop environments are the primary installers and users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life and edge retention\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design balances chip clearance and finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for smooth cutting action in a range of materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eStub length for maximum rigidity in shallow-depth operations\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids across a broad material range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 1\/8 inch collet or end mill holder setups on CNC machining centers, knee mills, and similar milling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly sized collet, end mill holder, or shrink-fit toolholder matching the 0.125 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before tool changes. Verify runout with a dial indicator after seating, as excessive runout accelerates wear on small-diameter carbide tools. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches (1\/4 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: 1.5 inches (1-1\/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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 414\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 414-1250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741944348978,"sku":"414-1250","price":22.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5a9a813d1c76c72f78664f13a1cc341.jpg?v=1788834481","url":"https:\/\/voomisupply.com\/products\/osg-414-1250-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
